How Ozone Extends the Life of Linens October 17 2017, 1 Comment
A staple of every hotel visit are the luxurious white linens and robes provided to guests. Keeping these items clean is important to the satisfaction of hotel guests. Using an ozone laundry system is one way hotels can keep linens sanitized while cutting costs.
Many hotels are beginning to realize the benefit of using ozone in their laundry services. Ozone has been proven to be a cost cutting measure for many reasons. Ozone is a powerful oxidant that can disinfect with less contact time and concentration than that of all other weaker disinfectants.
To be effective, ozone must be used in cold water exclusively. According to the EPA, as water temperature increases, ozone becomes less soluble and less stable. The elimination of hot water reduces the carbon footprint of the building and saves money in utility costs. Amar Sohi, a Holiday Inn Express & Suites general manager, reported the success of his installed ozone laundry system to WQP Magazine. Sohi has found the installation of the ozone system has reduced his utility costs by roughly 85 percent.
The use of ozone can also eliminate entire steps in the laundry process which ultimately saves water usage. Since less water is used in ozone laundry techniques, it takes less time to dry linens. This is another cost and time saving advantage of laundry utilizing the natural power of ozone.
Hotels are not the only ones that can benefit from an ozone laundry system. Julian Rich, the CEO and President of Penacook Place Nursing and Rehabilitation Center, installed an ozone system to the facility’s laundry. He told the Institute for the Advancement of Senior Care that the ozone system has had many unexpected benefits: “The laundry turns out much whiter. You can set towels washed with ozonated water next to towels washed traditionally, and the superior whitening effect of ozone is immediately and dramatically obvious. Another benefit is that the laundry room is much cooler in the summer. The decreased need for hot water reduces room temperature by a great deal, and anything we can do to make our staff more comfortable at work is a plus.”
Traditional utility companies are also experiencing the benefits of ozone laundry system that decrease energy use. According to WQP, “Utility companies appreciate energy savings, too—so much so that in many states they offer rebates that will pay, for example, up to 50% of the equipment costs for installing an ozone laundry system.”
The benefits of ozone don’t have to be based on opinion alone. At North Carolina State University’s Physical Testing Laboratory - College of Textiles the first tests were conducted to determine the efficiency of ozone laundry compared to traditional laundry processes. Juan Marcano, President and CEO of Riteway Linen Services told WQP Magazine that based on his experience, linen replacement is at an annual rate of 20-30% with traditional laundry operations. The study revealed using ozone in laundry slashed the annual replacement rate in half to around 12 to 15 percent.

Water Cooler Sanitation in the Workplace October 16 2017, 0 Comments
According to Beverage Marketing, Americans are consuming water in greater quantities than ever before, drinking 1.2 times more water than they were a decade ago. A common place many adults may rely on to quench their thirst is the office water cooler. These shared water coolers can become a breeding ground for harmful bacteria and other contaminants.
A study conducted by the Quebec Public Health Center found that 28% of the water dispenser samples from workplaces were contaminated by a least one coliform or indicator bacterium and or at least one pathogenic bacterium.
The New York Daily News described the potential dangers of workplace water coolers: “They may be the quintessential “gathering place,” but they’re also a big threat to staying healthy," says David Fowler, who works for Wellness Enterprises. “Water coolers are a rising concern,” he continued. “Someone has to handle the jug and stick the jug into the cooler itself. And the little spout and the internal mechanism are breeding ground for viruses and bacteria. Plus, people are always shoving their plastic bottles right up to the spout to fill them - and for all you know, some of these people may be coming down with a flu the next day.”
“Whereas microbiological standards exist for bottled water, the same product once installed on a dispenser is generally not regulated and is rarely controlled,” Fowler said. Besides potential contamination when cleaning the jug, many that own a water cooler don't know proper cleaning procedures. “As for the participants in our study, only 44% of those possessing water coolers in residences and 36% of those possessing water coolers in workplaces had been informed of the necessity of cleaning the equipment, let alone how to do it.”
The study concluded, “We should be cognizant of the quality of the water dispensed from water coolers. Although it is possible to manufacture water dispensers which are less likely to become contaminated, vendors and suppliers of water dispensers should impress on their clients the need for regular maintenance of the equipment. In addition, studies determining the health impact of drinking water from dispensers should be undertaken, and public health authorities should be made aware of water dispensers as a possible source of contamination when investigating food- or water-related epidemics.”
In offices, there are an estimated 2.7 million germs on bottled water coolers. One way to limit the amount of germs is by washing the outside of the container regularly with ozonated water. Additionally, washing the inside of the container with ozonated water will oxidize bacteria and other harmful substances.
An alternative that many may use to clean water coolers is vinegar or bleach. This could leave behind a taste in the bottle and create a strong smell in the workplace. Ozone avoids both concerns because it is 3,000 times more effective than bleach and leaves no residual chemical behind.
The use of ozone with water coolers has its own set of benefits. According to WQP, these include:
- Improving taste
- Increasing storage life
- Maintaining a microbe-free environment
- Complying with federal and local health regulations
Consumer Focus recommended to BBC News that the exterior of water coolers should be cleaned once a week. In addition, they said bottle-supplied machines should be cleaned internally every three months, while plumbed-in versions should have their filters changed every six months.
How to Setup a Saltwater Fish Tank October 13 2017, 0 Comments
- 30-gallon tank
- Caribbean live sand
- Tap water
- Aqua-6 Multi-Purpose Ozone Generator
First, we filled the bottom of the tank with Caribbean live sand
The live sand is critical to the success of saltwater tanks because it is coated with living and breathing bacteria, which is important for coral
We chose to mix our own saltwater, however it’s possible to buy premixed saltwater
We mixed 1.2 pounds of salt for each 4-gallon bucket
We used 5-gallon buckets, but filled them with 4-gallons of tap water to allow space for mixing
Then, we poured the saltwater into the tank
Next, we turned on our filter
We made sure to use a brand-new filter so that it did not have residue from our freshwater tank
Then we turned on our Aqua-6 ozone generator to setting 6
We have had success with the Aqua-6 keeping our freshwater tank clear and odor free
We also turned on the heater
The water needs to be 77 degrees Fahrenheit before the rocks could be placed in the tank
Once the temperature was reached, we placed the rocks in the tank
- The water, sand and rocks need to sit for two weeks before putting fish or coral in the tank
- After a week, we noticed growth on some of the rocks and even a tiny starfish
- Next, we set up our UV light that will recreate the sun for our saltwater fish.
- The light has a timer and is set to turn off after we have left the office.

Advantages of Ozone in Spas October 12 2017, 0 Comments
Many enjoy the health benefits of sitting in a spa daily. They are proven to reduce stress, ease muscle pain, improve circulation, reduce arthritis pain, and encourage increased blood flow. To enjoy these benefits, spa owners must make sure their spa is clean and well maintained. According to Pool and Spa News, “Recreational water illnesses remain the No. 1 health risk plaguing the aquatic industry.”
Many spa owners use chlorine to maintain their spa, however there are some water illnesses that are very resilient to the chemical. One that is a major concern is cryptosporidium parvum. “According to the National Swimming Pool Foundation’s Pool & Spa Operator Handbook, it takes 20 ppm of chlorine at 12.75 hours to inactivate crypto.” Ozone is able to destroy cryptosporidium at a rate of 99.9%.
A 2005 article in “Water Conditioning and Purification” estimated that up to 85 percent of the chlorine used in a spa without any other water sanitation system is consumed in oxidation processes, just 2.5 percent is used for disinfection, another 2.5 percent maintains residual levels in the water and 10 percent is destroyed by the hot water in the tub.
“The most efficient, effective way to inject ozone into spa water is through a Venturi injector, which uses the flow of water through a specially constructed pair of cones to draw ozone into the liquid and create an ozone/water slurry. To maximize the draw of gas into the flow and ensure thorough mixing, both cones and the orifice of the Venturi injector must be exactingly engineered and constructed,” Aqua Magazine writes.
A2Z Ozone’s Spa and Pool products utilize the venturi injection method to pump fresh ozone into the spa water. Once installed, spa ozone generators are maintenance free.
A2Z Ozone manufactures two spa ozone generators. The Aquatic is made for larger spas fitting up to 10 people, or spas holding up to 1,500 gallons of water; approximately 5,678 liters of water. The Aquatic 2 is perfect for small spas that hold up to 500 liters, or 132 gallons.
Ozone Removes Arsenic From Drinking Water October 05 2017, 0 Comments
It’s no secret that arsenic is extremely toxic to humans. However in 2014, WHO estimated that about 200 million people worldwide are exposed to concentrations exceeding the recommended limit of 10 micrograms per liter of water. Most live in Bangladesh, India, Vietnam, and Nepal, according to Science Magazine.
Drinking water contaminated with arsenic is a large problem around the world, but the United States can also be impacted. The EPA estimates that approximately 13 million people in the United States routinely drink water with more than 10 ppb of arsenic.
According to the Water Quality Association, “Higher levels of arsenic tend to be found more in ground water sources than in surface water sources (lakes and rivers) of drinking water. Compared to the rest of the United States, the western states have more water systems with arsenic levels greater than 10 micrograms per liter (µg/L, ppb). Parts of Midwest, New England, and Texas have some systems whose current arsenic levels are greater than 10 µg/L (or ppb).”
Since those who depend on well water in the United States will be accessing groundwater, well users must also be vigilant with arsenic levels. Private well owners are solely responsible for the quality of their drinking water. The EPA does not regulate private wells and well owners must do their own testing to determine water quality.
Drinking water contaminated with arsenic can have many adverse health effects. The Water Quality Association reports serious skin problems, endocrine disruption, cancer (skin, bladder, lung, kidney, liver, prostate) and harm to the cardiovascular & nervous systems can result. Ingestion of as little as 100 milligrams (mg) can result in severe poisoning to humans. While arsenic levels found in groundwater are typically much lower, it’s important to have water treatment methods that can remove the chemical to limit long-term exposure.
There are typically two species of arsenic in drinking water: arsenic III and arsenic V. A report from UMass Amherst on healthy drinking water says,“The numbers III and V describe the valence of the arsenic in the molecule when the arsenic compound is dissolved in water. This dissolved form of an element or compound in water is called an “ion.” The form of the arsenic, III or V, is very important relative to the effectiveness of many treatment methods. Arsenic V is generally much easier to remove from water than arsenic III.”
Effective ways to convert arsenic III to arsenic V will ease the water treatment process. A study at the University of Houston by Dr. Dennis Clifford and Ganesh Ghurye examined the effectiveness of seven oxidants for converting arsenic III to arsenic V. They choose to study the effectiveness of chlorine, permanganate, ozone, chlorine dioxide, monochloramine, ultraviolet (UV) irradiation and Filox, a manganese-oxide-based solid.
It’s important to keep in mind the EPA has standards for the levels of arsenic in drinking water. The MCL (Maximum Contaminant Level) is 0.010 mg/L (or ppm) while the MCLG (Maximum Contaminant Level Goal) is zero.
The scientists concluded that chlorine successfully oxidized As III to As V under all the conditions tested. Iron (0.3 and 3 mg/L) and manganese (0.2 mg/L) had little, if any, effect on As III oxidation. Although sulfide (1.0 and 2.0 mg/L) slowed As III oxidation by chlorine, complete oxidation still was obtained in less than one minute.
Ozone was extremely effective at As III oxidation; complete oxidation was achieved in less than 15 seconds. No adverse effect was observed in the presence of either dissolved manganese or dissolved iron, but sulfide slowed As III oxidation considerably.
A2Z Ozone designs and manufactures ozone generators to fit a variety of applications. The Industrial Series is heavy-duty and designed for continuous ozone output in water treatment facilities. To learn more about the Industrial Series, click here.

Well Water Free of Pathogens October 03 2017, 0 Comments
According to the CDC, over 15 million U.S. households obtain their drinking water from private wells. The EPA does not regulate the water quality of private wells instead leaving the safety up to the owner of the individual water source.
"Although the United States has one of the safest drinking water supplies in the world, sources of drinking water can still become contaminated through naturally occurring chemicals and minerals (for example, arsenic, radon), local land use practices (for example, pesticides, chemicals, animal feeding operations), malfunctioning wastewater treatment systems (for example, sewer overflows), and other sources. Contamination of a private well can impact not only the household served by the well, but also nearby households using the same aquifer,” the CDC says.
The top causes of outbreaks in wells are:
- Hepatitis A
- Campylobacter, E. coli (tie)
- Cryptosporidium, Salmonella (tie)
- Arsenic, Gasoline, Nitrate, Phenol, Selenium (tie)
Ozone is a powerful disinfectant and can be used to effectively sanitize well water. Using ozone treatment for well water means “removing iron, manganese and hydrogen sulfide to below the U.S. Environmental Protection Agency (EPA) acceptable levels including bacterial control.” WQP says, “Ozone is the most powerful, natural oxidizer and disinfectant of practical use known to us. It is easy and safe to use and can be applied by simply using existing water treatment equipment and technology.” They add, "Ozone is a sterilizer, and it will kill any airborne microbes prior to being injected into the water."
How it works
According to WQP Magazine, “Ozone kills bacteria by oxidizing the organic material in bacterial membranes, which weakens the cell wall and leads to cellular rupture. This exposes the organism to the external environment, which causes almost immediate death of the cell. The process is similar to being cut open by a knife.”
The process of using ozone treatment on well water is simple. WQP describes the three easy steps as:
- Ozone injection/oxidation. Ozone is triatomic oxygen (O3) that has very high oxidizing power. It is a gas produced from air and high voltage electricity. The injection of the ozone into the water produces tiny ozone bubbles, which saturate every drop of water. At this point oxidation of iron, sulphur and manganese is immediate.
- The elimination (off gassing or venting) of the ozone and other gases/odors such as sulfur is known as aeration. This occurs by an ozone stripping action. As water flows down the off gas tank, ozonated water rises and strips any gas in the incoming water. There are two types of venting devices on the market. Electric self-cleaning types and float types that only release gas. The float types tend to require more maintenance than the electric type.
- The final step for removing the oxidized material is filtration. There are several media on the market. The idea is to use a medium that has low water waste (backwash), high service flow and high removal capacity and requires no chemicals during regeneration. Mechanical filtration is all that is necessary, and Birm, Greensand, and Centaur typically are not necessary.
While there are alternatives that can be used to disinfect well water, ozone has its unique benefits. Unlike a common substitute, chlorine, “ozone equipment requires very little space and no ongoing chemical costs.” Another advantage is the “absence of hazardous chlorine byproducts, storage of hazardous chemicals, absence of chemical odors and the lack of constant replenishment of the chlorine feeder.”
The CDC recommends testing private well water at least once a year. For more guidelines on well testing, click here.

Ozone Cell vs Ozone Plate September 26 2017, 0 Comments
Here at A2Z Ozone, our ozone generators utilize either an ozone cell or an ozone plate. Each has its own advantages and reasoning for why one is used over the other on certain units. In this post, we will dive in to some of the distinctions between the two technologies.
An ozone cell can be controlled more.
Because space is more limited, only a small amount of air can be in the cell.
Ozone cells lasts longer than ozone plates.
All of our units have replaceable parts, watch the video below to see the replacement of an ozone cell:
An ozone plate creates more ozone.
Air goes over the surface of an ozone plate, meaning a higher concentration is made with the oxygen converter.
While the plate doesn’t last as long, it can be replaced cheaply.
- As a general rule of thumb, we recommend replacement plates after either 2 years or 2000 hours of use.
- Replacement plates for the A7K a Air-7000 can be found by clicking here.
One unique feature of an A2Z Ozone plate is that it can be shaved, which is the only one on the market capable of this.
Ozone plate has a larger blower.
An ozone plate is more compressed, therefore hotter.

Ozone in Aquaculture September 25 2017, 0 Comments
The ocean is running out of fish.
WWF reported, “Two-thirds of the world's fish stocks are either fished at their limit or over fished. The U.N. Food and Agriculture Organization (FAO) has estimated that 70 percent of the fish population is fully used, overused or in crisis.”
In 2016, EcoWatch reported the average person is “now eating roughly 44 pounds of fish per year compared to only 22 pounds in the 1960s.” This increase in fish consumption has forced industrial fishing companies to adopt new strategies to keep up with global demand.
Advances in technology have allowed us to catch fish that are farther out at sea and live deeper in the ocean than ever before. This increase in tastes of deep fish has grave results for their populations. “Unfortunately, these deepwater fish don’t reproduce until they’re at least 10 years old, making them extremely vulnerable to overfishing when the young are caught before they’ve had a chance to spawn,” National Geographic says.
Deepwater fish aren’t the only species being impact by overfishing. In 2006, Science reported, “All species of wild seafood will collapse within 50 years, according to a new study by an international team of ecologists and economists.” Stanford says "collapse" was defined as a 90 percent depletion of the species' baseline abundance. “Wild fish simply can’t reproduce as fast as 8 billion people can eat them. So we need better management of fishing. Our ecosystems, food security, jobs, economies, and coastal cultures all depend on it,” National Geographic says.
Plummeting numbers of wild fish has led to an increase in aquaculture. According to the NOAA, aquaculture “refers to the breeding, rearing, and harvesting of plants and animals in all types of water environments including ponds, rivers, lakes, and the ocean.” The FAO report, The State of World Fisheries and Aquaculture 2016, revealed that for the first time, more farmed fish were consumed than wild fish globally.
“Aquaculture provides reasonably priced, good quality, highly nutritious food while helping to maintain the long-term sustainability of wild caught fisheries and the environment. It is estimated that wild harvest fisheries have reached maximum sustainable yield while the world’s appetite for seafood is growing. U.S. aquaculture can satisfy that demand in an environmentally friendly and sustainable manner," the National Aquaculture Association says.
One component of aquaculture is the use of ozone treatment in fisheries. Ozone is utilized in many Recirculating Aquaculture Systems (RAS) worldwide. “Increasing the daily water exchange rate in an RAS will remove accumulated colloidal solids, refractory organics and nitrite, to the detriment of water budgets and the cost of heating or cooling the system. The alternative method of removal is to breakdown these organic wastes using an oxidizing agent, such as ozone. Ozone is also widely used to sterilise supply and effluent water for RAS to remove pathogens," the New South Wales (NSW) Government says.
“Ozone removes fine and colloidal solids by causing clumping of the solids (microflocculation), which facilitates removal by foam-fractionation, filtration and sedimentation,” NSW Government says.
Benefits of using ozone in aquaculture:
- Removes fine and colloidal solids
- Removes dissolved organic compounds (DOC)
- Removes nitrate
- Disinfection to lessen the spread of diseases

Is Ozone Safe? September 18 2017, 0 Comments
Have you ever experienced the fresh smell that is created after a lightning storm? If you answered yes, that means you’ve smelled the pure aroma of ozone. With oxidizing power 3,000 times more effective than bleach, ozone is the second most powerful oxidant in existence (deadly fluorine gas is first). Ozone is proven to be one of the most effective and methods to safely remove bacterial, viral, and fungal activity. Ozone has many positive benefits, however some may not know how to utilize an ozone generator in the safest way.
What is Ozone?
When used correctly, ozone is a safe and effective sanitizer for air, water and oil applications. Ozone, also referred to as active oxygen, is simply another form of oxygen. Three oxygen atoms make up ozone (O3) instead of two atoms that form oxygen (O2). The amazing qualities of ozone have been occurring naturally since the beginning of time.
Ozone is created when ultraviolet rays emanate from the sun, split the oxygen molecules and form an unstable oxygen molecule (O2) and a highly unstable oxygen atom (O1). The molecule being oxidized then bonds with the loose (O1) atom, creating an oxide of the substance thus (O3). Another manner in which ozone is formed is through the high energy contained within electrical discharges, which occur during lightning storms.
In addition to occurring naturally, ozone can also be reproduced scientifically in safe, controlled quantities. This is not a new technology; rather a thoroughly tested, safe and highly-utilized reproduction of nature’s gift to us. The first recorded publication on the value and benefits of ozone was published in an 1885 Florida Medical Association paper entitled "Ozone" by Charles J. Kenworthy, M. D., M.R.S.V. This shows that ozone was used in the medical & scientific fields in the U.S. before 1885. A2Z Ozone utilizes cold corona discharge to safely produce ozone. This is a common method that most ozone generators utilize today because it can create ozone at many different concentrations needed for a wide array of applications.
How to Use Ozone Safely
Ozone generators can be used in unoccupied areas—just remember the three P’s: no People, Pets, or Plants. A2Z Ozone’s in-home generators are designed to produce just the right amount of ozone to effectively sanitize your water and air, but not strong enough to exceed recommended EPA levels. The current EPA standard for in-air ozone is .05 ppm. If inhaled in large amounts, ozone can become detrimental to health so it is important to run units only in unoccupied areas and be sure to remove valuables before starting the unit.
Many of our units feature timers that will shut the unit off after it runs for the selected amount of time. This allows users to turn the unit on and set the timer before exiting the room. Return after the unit has had enough time to run the setting and had 30 minutes to 1 hour to allow the ozone to dissipate, reverting back to oxygen. Keep in mind, as rooms increase in size, fan speed and ozone timer should increase also.
OHSA has safety guidelines regarding ozone exposure are:
- 2 ppm for no more than 2 hours exposure
- ppm for 8 hours per day exposure doing light work
- 08 ppm for 8 hours per day exposure doing moderate work
- 05 ppm for 8 hours per day exposure doing heavy work
Ozone has a 20-30 minute half-life in the air meaning that its concentration will break down quickly. After running a unit, be sure to wait out the half-life before returning to the room to allow the ozone to dissipate. If the smell of ozone is still strong after waiting 30 minutes, open windows to air out the room.

Ozone in Aquariums September 13 2017, 0 Comments
Many have fond experiences of visiting aquariums that are home to large marine mammals and other exotic fish, but do you know how the water is maintained? Water quality is crucial for the health of marine life. Fish and marine mammals that live in aquariums produce toxins that are released into the surrounding water that must be maintained by aquarium staff. Ozone is commonly used in large scale aquariums to keep tanks clean. The use of ozone in tanks big or small can help reduce the odors typically released by aquariums and create a healthier environment for the animals inside.
Application in Large Aquariums
One example of aquariums taking advantage of the strong disinfecting powers of ozone is at Marineland in Ontario, Canada. Marineland describes why they have chosen to use ozone over other chemicals, “Here at Marineland, we use ozone to maintain a high level of water quality for our marine mammals - without the high residual chlorine levels that were required in the past. The advantage of ozone disinfection as compared to chlorine disinfection is multiple.”
They continue, “Ozone is a more effective disinfectant than chlorine and removes viruses and lowers the color and turbidity. Ozone also removes suspended solids. Unlike chlorine, ozone does not change the pH of the water, nor does it react with the remaining organics in the water to form carcinogenic trihalomethane.”
How does it work?
Marineland describes how ozone use in their tanks works to keep the water clean without the use of other harmful chemicals: “Ozone is a colorless gas that is formed by passing oxygen through an electric field. The rate and efficiency of ozone production is affected by many variables such as air flow, percent of oxygen in gas feed, dew point of gas feed, air pressure, cooling water temperature, voltage and frequency applied to electrodes.”
Because of its short half-life, ozone will decay soon after it is produced. The half-life of ozone in water is about 30 minutes, which means that every half hour the ozone concentration will be reduced to half its initial concentration.
Ozone works so well as a fish tank disinfectant that we even use it for our own fish here at A2Z Ozone! We use the Aqua-6 to provide a clean environment for our fish. It keeps Charlie Brown, our gold twinbar platy; Snoopy, our glowlight tetra; Linus, our dwarf gourami; and Lucy, our bala shark; Schroeder, our julii cory; and Peppermint Patty, our rainbow shark happy!
We have found that over time, ozone is a more cost effective way to treat water. Many customers also experience a decrease on their reliance to other chemicals.
We recommend our SP Series or MP Series for water applications. To view these product lines, click here.
The Aqua-6 is ideal for smaller amounts of water.
Ozone in the Dairy Industry September 12 2017, 0 Comments
Sanitation practices on farms that produce dairy products are essential to the quality of the final product. A wide variety of dairy products can benefit from the use of ozone treatment as a disinfectant. Some common products that are improved with the use of ozone include fluid milk, powdered milk, and cheeses. Each farm must examine their sanitation procedures to ensure a micro-biologically safe product reaches consumers.
In a April 2016 study, scientists examined the impact of ozone treatment on sanitation practices used in dairy farms. The International Journal of Diary Technology says, “Ozone treatment is a cost-effective and eco-friendly food-processing technology.” Ozone is the second strongest common oxidizing agent after deadly fluorine and also leaves no harmful chemical residue behind.
The use of ozone to treat dairy products is less expensive than other methods. Researchers on the project claim ozone “can be generated on demand on-site and, as opposed to conventional chemical sanitizers, it requires neither transportation nor storage.” Ozone treatment also uses less power consumption to function than other methods, “In addition, the running costs of ozonation systems are low because they only consume a limited amount of electricity.”
The power of ozone also doesn’t lead to downsides when the product is ready to consume. “Despite being a highly effective disinfectant, ozone does not leave a chemical residue on either food or food contact surfaces because it quickly auto decomposes to nontoxic products, thereby reducing both the environmental impacts and costs of the company,” scientists said.
Heating processes are commonly used to treat the milk we all enjoy for consumption, however this can negatively impact its nutritional value and sensory properties. On the other hand, scientists found ozone did not negatively impact the nutritional values or taste of the fluid milk studied.
Scientists see the long term benefits of ozone use in the dairy industry. They concluded, "The clear and convincing communication of the overall benefits provided by this advanced, cost-effective and environmentally friendly technology is a prerequisite to widespread adoption and usage of ozone by the global dairy industry."

Study Finds Ozone Treatment Extends Shelf Life of Fish September 11 2017, 0 Comments
Ozone is not new to the fish industry, scientists have been attempting to use ozone to prolong the shelf life of fish products since the 1920s. Ozone is successful at preventing spoilage in these products because it works as a disinfectant.
A study from a pair of scientists at the World Academy of Science examined the impact that ozonated water would have on freshly caught trout from fish farms. The team left the trout submerged in ozonated water for two hours to determine its impact on the product’s shelf life. The use of ozonated water greatly reduced the presence of bacteria on the fish studied.
The study concluded that “ozone treatment increases the shelf life of trout from 4 days to 6 days as compared to the control fish.” One key finding in the study is that ozone did not have an impact on the biochemical properties of the fish. This is an important discovery because the biochemical properties are key to the quality of the product including humidity, protein and free fat.
In fact, the ozone treatment positively impacted protein levels in the fish, “Ozone removes the contaminants which can destroy the protein resulting in detecting better level of protein compared to control.” Scientists found that the ozone treatment also left no residue on the fish, meaning the quality of the taste would remain intact.
The study concluded the following:
- Ozone treatment of fish slows down its bacterial growth significantly, resulting in lower counts of bacteria
- Ozone removes the contaminants from the fish skin causes to higher protein number
- Ozone treatment increases the shelf life of fish and helps in longer preservation time
- Ozone has no negative impact on the biochemical properties of fish such as humidity, protein and free fat
- Ozone leaves no residue on the fish and creates no changes on its color and flavor
We recommend the Aqua-6 for the washing of fish, meats and poultry.

Ozone is known to increase the shelf life of produce, however a study from Postharvest Biology and Technology reveals the impact of ozone is greater than previously thought. Professor Jeremy Barnes of Newcastle University said, “Ozone has been used as an anti-spoilage agent for years, but while we know it works, we didn't know why until this study.” Information released in the study shows produce that has been in contact with ozone can be protected from various diseases for up two weeks, even after it is removed from the gas itself.
Scientists have discovered the use of ozone gas alters the protein profiles of produce. A little goes a long way, “these findings show that only very low levels, no higher than that of an English summer day, are needed to observe the potentially beneficial effects.” Scientists exposed produce to Botrytis cinereal, also known as grey mold. "If you re-introduce a pathogen to a tomato that's been given ozone it doesn't grow anywhere near as voraciously as it does in a non-treated tomato," says Barnes
The ozone treatment was useful for a plethora of different pathogens introduced by scientists, “The extensive testing on tomatoes discovered that this one treatment can prevent a whole range of pathogens growing on the fruit, without affecting its taste or look.”

Ozone Eradicates Deadly Bacteria September 07 2017, 0 Comments
In 2011, New Atlas, a technology publication, reported that over “100,000 people die every year in North America alone, due to hospital-acquired infections.” This discovery, made by Dr. Dick Zoutman at Queen’s University in Canada, demonstrates the importance of hospitals maintaining a clean environment for the well-being of their patients.
Here's where ozone comes in. To limit deaths from hospital-acquired infections, Dr. Zoutman has developed a way to keep hospitals cleaner using the natural sanitizing power of ozone. Ozone gases are pumped into the area to kill bacteria without having a negative impact on medical equipment in the room.
Dr. Zoutman is no stranger to studying the spread of bacteria, his research has led to “producing over 100 publications, has been understanding the prevention and control of healthcare associated infections and related medical quality issues. Dr. Zoutman’s work and collaborations have spanned the globe from North America, South America, the Balkans, the Middle East and Africa in the areas of infectious diseases surveillance, prevention and pandemic preparedness.”
According to his methodology, Dr. Zoutman used “ozone gas at 50-500 ppm was combined with 3% hydrogen peroxide vapor in a test chamber and upscaled in rooms measuring 82 m3 and 90 m3 in area.” The combination of gases was then pumped into an area of hospitals that requires pristine cleanliness, the operating room.
The use of this process was described as a great success because “it sterilizes every surface within less than one hour.” This process reverts to a natural defense mechanism used by the human body on a daily basis, during which “antibodies create ozone and hydrogen peroxide, in order to kill germs.” According to Queen’s University, the disinfectant process utilizing ozone “is said to leave the room with a pleasant smell, and doesn't adversely affect medical equipment.”
The study from Dr. Zoutman and his colleagues concluded, “The ozone hydrogen peroxide vapor system provides a very high level of disinfection of steel and gauze surfaces against health care-associated bacterial pathogens. The system is an advanced oxidative process providing a rapid and effective means of disinfecting health care surfaces and spaces.” This application of an ozone gas combination is just one way ozone can be used to improve the quality of lives around the world.
We routinely recommend our commercial units for doctors and dentists who want to keep their offices smelling fresh and eradicate harmful bacteria in a natural, safe way. A2Z Ozone's products for this application can be found by clicking here.
Please Note: Be sure to only use your ozone generator in an unoccupied area. Our units produce high amounts of ozone. It is not safe to run the unit in an occupied area for more than 1 minutes. Be sure to remove any valuable items, pets and/or plants before you use the ozone generator. Do not breathe in ozone directly.
Ozone's Role in Bottled Water August 28 2017, 0 Comments
Water Quality Products Magazine says water bottlers have been using ozone as a treatment method since the 1970s because it delivers a safe and clear product to consumers. Its key purpose is to act as a disinfectant.
According to Water Quality Products Magazine, "Ozone treatment is one of the most effective microbiological barriers that water bottlers can employ to protect consumers against microorganisms." Ozone works to remove bacteria that could be harmful to the consumer, however it also is effective at removing unwanted discolorations in bottled water.
"Ozone disinfection enabled the water bottler to produce high-quality, storage-stable bottled water free of byproducts and the taste and odor associated with the use of chlorine for disinfection and oxidation," Water Quality Products Magazine continued. They even partially credit the boom of the bottled water industry in the 1980s and 1990s to the efficiency of the ozone treatment process!
Ozone works to sanitize the following during the bottling process:
- Disinfects water against all microorganisms
- Disinfects bottles
- Disinfects bottling equipment and machinery
- Disinfects air against airborne microorganisms
Ozone generators create an output of ozone gas that is then brought into contact with water in an ozone contactor. During this stage of the treatment process, ozone dissolves in the water and the remaining undissolved ozone gas is released outside of the facility. "It does the job and disappears," Water Quality Products Magazine says. Ozone also plays a key role in disinfecting water bottles that have been recycled and used again.
"The ozone treatment process is an integral part of the drinking water treatment plant operation in more than 3,000 municipal water installations worldwide," Water Quality Products Magazine says. They report there are also 400 ozone drinking water installations in the United States.
One example of ozone treated bottled water is made by Kroger, the grocery chain headquartered in Cincinnati, Ohio. Kroger's bottled purified drinking water is "processed by advanced filtration, ozone and reverse osmosis technologies," according to the label.
If you've had Kroger bottled water, you've tasted the benefits of using ozone.

How Ozone Sanitizes Pools August 23 2017, 0 Comments
If you’ve spent time at a hotel pool this summer, there's a 1 in 6 chance you've been exposed to contaminated water that can cause illnesses, according to CBS News.
CBS News reported, “The Centers for Disease Control and Control and Prevention found that, aside from childcare facilities, that 16,569 hotels, resorts and motels had the highest rate of closure due to serious code violations, mainly low disinfectant in the water to battle bacteria, about 15% or 1 in 6 hotel inspections.”
Low levels of disinfectant, which merit serious code violations, have real implications for swimmers. Cryptosporidiosis, an intestinal parasite, has been wreaking havoc on those who visit public pools, splash pads and waterparks. The CDC describes symptoms as, “profuse, watery diarrhea that can last up to 2–3 weeks in immunocompetent patients and can lead to life-threatening wasting and malabsorption in immunocompromised patients.”
According to CNN, in Ohio alone, nearly 2,000 people became sick from cryptosporidiosis last year. 42% of those outbreaks were linked to aquatic venues. Lubbock, Texas is currently battling an outbreak. In a press release, the city of Lubbock said, "Over 40 cases have been reported in the last 30 days compared to 25 cases reported in all of 2016. Cryptosporidiosis is caused by the cryptosporidium parasite, and there are an estimated 750,000 cases in the United States every year."
This contamination is showing no signs of slowing down, outbreaks of cryptosporidiosis linked to public pools have doubled in the U.S. from 2014 to 2016. The recent uptick in these outbreaks have been caused by poor public pool sanitation. WHEC reported, “Studies suggest a quarter of them are caused by bacteria, viruses or parasites that should have been killed by proper pool treatment and chlorination.”
The CDC reported, “Fecal-oral transmission of cryptosporidium oocysts, the parasite’s infectious life stage, occurs via ingestion of contaminated recreational water.” The CDC recommends, “Young swimmers aged <5 years are more likely to contaminate the water because they are more likely to have inadequate toileting and hygiene skills; therefore, prevention efforts should focus on their parents.”
Swimmers expose pool water to urine and sunblock, which both contain nitrogen. These levels of nitrogen can eat away at chlorine in the pool. In turn, lower disinfectant levels in pool water can allow cryptosporidiosis to spread.
However, children aren’t the only ones to blame for high levels of urine found in pools, 1 in 5 adults also admitted to peeing in a public pool.
What should management change?
Keeping contaminated swimmers out of the water is one way to slow the spread of these infections, but pool managers also have a role to play. Those responsible for maintaining public pools should reevaluate the procedures they use to keep pools clean.
Maintaining appropriate chlorine levels can help, however according to the CDC, "Crypto is the most common cause of diarrheal illness and outbreaks linked to swimming pools or water playgrounds because it is not easily killed by chlorine and can survive up to 10 days in properly treated water. Swallowing just a mouthful of water contaminated with crypto can make otherwise healthy people sick for up to three weeks with watery diarrhea, stomach cramps, nausea or vomiting, and can lead to dehydration."
The bacteria features a hard shell that makes it increasingly difficult to be eradicated with chlorine. It is important that staff are trained properly to deal with the chemical and don't use too much in an attempt to stop the outbreak, which comes with its own set of health risks.
According to CNN, “equipment failure and human error can lead to the release of toxic chlorine gas at public pools and water venues.” In 2015, about 50 people were in an outdoor public pool in California when 34 began to vomit, cough or feel eye irritation, according to a CDC report. The incident was caused by a “chemical controller malfunction (that) allowed sodium hypochlorite to react with muriatic acid, leading to the release of toxic chlorine gas.”
Ozone vs. Chlorine
Ozone, a more natural alternative to chlorine, could be the answer to solving cryptosporidiosis outbreaks in public water facilities. Cryptosporidiosis is less resilient to ozone. Beth Hamil, a consultant for the ozone industry, told AQUA Magazine, "Certainly there are other ways to kill it, but in pools by far the best way to prevent outbreaks is with an adequately sized ozone system.”
She continued, "The Ct value for chlorine to achieve a three-log reduction in Crypto is 15,600. That equates to 20 ppm for 13 hours. The Ct value for commercial ozone systems is 1.52. It's literally 10,000 times more effective."
Ozone is faster and more effective than chlorine because chlorine needs to diffuse through the cell wall and disrupt bacteria's metabolism. Ozone rips open the cell wall from the outside, causing the cell contents to fall apart. This process is called cell lysing and is much more effective than chlorine's process of disrupting the metabolism. With ozone, after the destruction of the cell, O3 (ozone) simply reverts back to O2 (oxygen). The additional oxygen in the water creates a safe, clean and refreshing swimming experience.
A2Z Ozone manufactures swimming pool ozone generators, venturi injectors, manifolds, check valves and silica air dryers to help transform any current pool system.
Many customers have found the use of ozone can reduce reliance on other chemical usage by up to 95%, depending on weather conditions and pool characteristics.
The SP swimming pool models feature regulated ozone output in a compact, reliably built package featuring 3g, 5g, 8g and 16g/ozone output per hour. The SP series is can treat almost any size pool, ranging from 25,000 gallons to 200,000 gallons.

How Ozone “Vaccine” Strengthens Produce August 21 2017, 0 Comments
This blog has previously discussed the ways an irrigation system using ozonated water can benefit the longevity of agriculture, however research suggests using ozone gases directly to treat produce has its own set of advantages.
Scientists at Newcastle University in England have developed an ozone reliant method that works to save produce from spoilage. Fungal contamination is the most common culprit of produce spoilage with an “estimated 30 percent of harvested fruit and veggies falling victim to it.” Dr. Ian Singleton, a microbiologist helping to lead the project, explains the way ozone gases were used to impact produce in the study, “We found that when tomatoes are exposed to a burst of ozone it acts in a similar way to a vaccine, changing the fruits' defenses and bracing them against attack.”
This boost to the defense systems of produce ultimately extended the shelf life of the fruits studied by an average of two to five days. Intensifying the plant’s immune system is key to the success of this method because it was “found that tomatoes exposed to ozone became more fungus-resistant, even once they were removed from the ozone gas.” Scientists are working to find the sweet spot for ozone gases used on produce as too much of the material can cause spoilage.
Each fruit and vegetable differs on its ozone threshold. Ozone gases is a preferred, more natural method over other common sanitation treatments used on produce, “Countermeasures currently including synthetic fungicides and pre-package sanitation treatments involving the use of chlorine or bromine.” Dr. Singleton emphasized this human-friendly advantage in an interview saying, "Ozone is a viable alternative to pesticides as it is safe to use and effective against a wide spectrum of micro-organisms. Importantly, it leaves no detectable residues in contrast to traditional methods of preserving fresh produce."
The method has been used on a plethora of favorite produce including “strawberries, grapes, tomatoes and plums, without causing any deterioration in produce quality when used in the correct way.”

How Ozone Contributes to National Water Quality Month August 16 2017, 0 Comments
Here at A2Z Ozone, we love holidays. This August, we are celebrating National Water Quality Month. Ozone treatment is a process commonly used to treat the water we drink everyday. This includes both bottled water and wastewater.
There are many advantages to consider when drinking water that has been treated with ozone. The use of ozone does not add chemicals to the water and is still a stronger disinfectant than chlorine. The oxidizing properties also eliminate unwanted tastes or odors that could be caused by a variety of reasons. Water & Wastes Digest reported ozone is used in more than 2,000 installations worldwide to treat drinking water.
What does water quality mean?
There are many measures the EPA uses to determine water quality. The EPA first released the Water Quality Standards Handbook in 1983 and has done revisions over the years to keep the standards at the highest level of quality. Last updated in 2012, the handbook lists these as important criteria to meet quality water standards. The criteria used, according to Michigan State University, is as follows:
"Aquatic life criteria -- These values are based on how much of a certain chemical can be present in a water body before it may harm plant or animal life. The aquatic life criteria have been designed to protect both freshwater and saltwater organism’s exposure in both the short and long term."
"Human health criteria -- Pollutants can harm human health if people eat seafood or drink from contaminated water. Based on EPA research, values for this criteria outline how much of a specific pollutant can be in surface water before it may harm human health."
"Microbial/Recreational criteria -- Because bacteria or other pathogens can make surface water unsafe for human use, this criteria was developed to provide safe values for recreational activities, such as swimming."
"Biological criteria -- This criteria is being developed to provide indications about water quality based on what kinds and how many organisms are present in the water."
"Sediment and bedded sediment criteria guidance -- A variety of organisms, including worms and plants, live in the sediment at the bottom of rivers and lakes. These organisms can ingest pollutants found in the sediment or water column. Then the pollutant works its way up the food chain to threaten larger animals and humans. Since the food chain can be a conduit to pollution, the EPA has developed guidelines for the development of criteria on suspended and bedded sediment."
There are also state-specific water standards. Find out how the Clean Water Act impacts your state here.
Ozonating Waste Water July 18 2017, 0 Comments
Ozone in Waste Water Treatment – A2Z Ozone Inc.
It is extremely important to treat waste water effectively to prevent the spread of waterborne diseases to the environment. Recently, Ozone is growing in popularity as a method for waste water treatment due to its oxidizing properties. With advancements in ozone generator technology, many water treatment plants are starting to shift towards a more organic way to disinfect waste water. These generators convert oxygen into ozone by using either corona discharge or ultraviolet radiation. This produces a very reactive gas that can eliminate bacteria, mold, and other pollutants found in water.
Corona discharge is the most common method of producing ozone with generators. The ozone generators use oxygen or air as a fuel source to produce ozone gas. By exposing air/oxygen to a controlled, high-voltage discharge at a set frequency, high concentrations of ozone are produced. This air is then used by water treatment plants to treat wastewater. After ozone gas is generated, it is pumped into chambers containing wastewater to be disinfected. The ozone gas then oxidizes the wastewater, eliminating any pollutants or harmful microorganisms in the water.
- The ozonation process is faster than other chemical methods (10 to 30 minutes)
- Ozone is more effective than chlorine in eliminating viruses and bacteria
- Ozonation does not leave harmful residual chemicals since it decomposes rapidly
- There is no regrowth of microorganisms in the wastewater stream after ozonation
- Fewer safety problems associated with shipping and handling since ozone is generated onsite
Common Ozone Generator Terms July 11 2017, 0 CommentsBasic Terms and Definitions to Understand for Ozone Use – by A2Z Ozone
If you are just now researching ozone, you have probably come across terms you do not understand. And, I will be the first to admit, some of the words used to describe ozone probably are not real words. For instance, is ozonating a word? I cannot find it in the dictionary. However, we at A2Z Ozone use this term almost daily. Also, terms used to describe ozone vary depending on the purpose behind its use. So, for various applications, we want to include a list of basic terms and definitions.
- Ozonate (and ozonating) – the treatment or combination of a substance/compound with the use of ozone
- Ozonated water – water that has been disinfected through the process of ozonation

- Silica Air Dryer – device that is attached to ozone generators to remove water and condensation; helps relieve issues in ozone generators such as humidity, mildew, and corrosion
- Ozone Destructor – device used for industrial ozone generators with high output to keep ozone out of the air after use
- ppm (Parts Per Million) – term commonly used to describe the concentration of a solution in water or soil; one ppm is equivalent to 1 milligram of something per liter of water (mg/l) or kilogram soil (mg/kg)
- ppb (Parts Per Billion) – term commonly used to measure the concentration of a contaminant in soils and sediments; the number of units of mass of a contaminant per 1000 million units of total mass
- Application (as pertains to ozone) – How ozone can be used to benefit everyday life
- Ozonator – a portable, multi-purpose ozone generator that is used to ozonate water to clean vegetables, bathe, drink, and perform house chores
- Ozone Generator – a device used to produce ozone to kill pathogens through oxidization
- Ozone half-life – the time taken for ozone to fall to half its original value
- Ozonolysis – an organic reaction where the unsaturated bonds of azo compounds are split with ozone
- Residual chemicals – leftover chemicals after the ozonation process.
- ORP (Oxidation-Reduction Potential) – a measure of the cleanliness of water and its ability to break down contaminants; range of -2000 to +2000
- O3 - Colorless and water-soluble gas having a chlorine-like odor, formed in the upper atmosphere by the action of solar radiation on oxygen; another form of Oxygen where three atoms merge to form the Oxygen molecule as opposed to two
- Ozone Solubility – the property of an Ozone solute to dissolve in a solid, liquid, or gaseous solvent; Ozone gas is 13 times more soluble in water than Oxygen gas
The History of Ozone July 05 2017, 0 Comments
The History of Ozone – A2Z Ozone, Inc.
Ozone is one of the most basic elements of nature that is also known to be an oxidizing force. With the creation of Ozone generators, this natural element can be used as a natural purifier to benefit our everyday lives. You can now use Ozone to perform simple tasks such as cleaning water and vegetables, getting rid of foul odor, and killing pathogens. With all the development in the Ozone phenomenon, you might just stop and wonder how everything started. Let’s take a look at the history of Ozone.
The chemical known as Ozone gas was officially discovered in 1840 by Christian Schonebein, a German professor of physics and chemistry at the University of Basel. While conducting experiments, Schonebein noticed a unique smell that was emitted from his electrifier. He later called this gas ‘Ozone,’ which is derived from “Ozein,” the Greek word for scent. Following Schonbein’s discovery, scientists began to conduct studies on the disinfecting abilities of Ozone.
The first ozone generator was built by German scientist and inventor Ernst Werner von Siemens. Although the first generator was relatively simple and inefficient, von Siemen’s introduction of Ozone purification prompted a wave of pilot projects that researched the disinfecting mechanisms of Ozone. Researchers in Europe continued studying Ozone’s properties, and by the early 1900s, the first large-scale application of Ozone took place in France. In 1906, the French city of Nice started using Ozone to purify drinking water for the entire city.
While many countries began to use Ozone to clean their water supplies throughout the 20th century, the discovery of chlorine halted the increase in Ozone usage throughout the world. Although chlorine appeared to be a suitable alternative to Ozone, the discovery of potential side effects (the production of harmful byproducts called trihalomethanes) prompted people to shift to Ozone disinfection. Additionally, it was discovered that ozone oxidized micropollutants in surface waters faster than chlorine.
With tens of thousands of illnesses caused by indoor pollution each year, it is necessary for us to have clean air and water in our lives. Ozone has gained tremendous popularity as a natural purifier because it has the unique flexibility to solve a wide array of everyday problems. Whether it is home air treatment or commercial/large-scale usage, Ozone is truly the most effective way to purify air and water.
Best Way to Grow and Protect Your Agriculture June 29 2017, 0 Comments
Ozone in Agriculture – A2Z Ozone, Inc.
Ozonating water can provide users with many benefits. Whether it’s drinking ozonated water to boost oxygen levels in the bloodstream or washing vegetables with ozonated water to extend shelf life, ozone has numerous applications in our everyday lives. However, did you know that ozone can also be used in agriculture to boost the yield of crops? Let’s take a look at the benefits of using ozone in agriculture!
When crops are infected by disease, the results can be very detrimental to farmers. Irrigation using ozonated water helps protect crops against these contagious diseases by eliminating any harmful microorganisms on the plants. Ozonated water destroys bacteria, viruses, and fungi, which are difficult to fight using other alternative methods.
Since ozonated water has a higher concentration of oxygen than regular water, irrigating with ozone can promote better growth. The ozonated water that is used is free of viruses, bacteria, and any other microorganisms. By using ozonated water, crops can thrive in the best conditions possible, obtaining faster growth and better yield!
Although pesticides and chemical agents can be used to disinfect crops, the residual chemicals left by these methods can be harmful to consumers of the produce. When using ozonated water to irrigate crops, the only byproduct is oxygen! After ozone disinfects and destroys microorganisms on the crops, it decomposes back to oxygen, leaving no harmful material behind.
How Does Ozone Work? June 27 2017, 0 Comments
How Does Ozone Work? – A2Z Ozone, Inc.
What is it?
Simply speaking, ozone is just another form of the oxygen that we breathe every day. However, instead of two atoms, ozone possesses an unstable third oxygen atom. This extra atom can oxidize any organic material, making ozone one of the most powerful oxidants in the world. Because of its oxidizing power, ozone is frequently used to eliminate contaminants such as bacteria, viruses, and odors.
How is it Produced?
Ozone can be produced both naturally and scientifically. In nature, ozone is created when ultraviolet rays from the sun split oxygen (O2) molecules into two unstable atoms: O2 and O1. The loose O1 atoms that is being oxidized then bonds with other oxygen (O2) molecules to form ozone (O3). Another natural way ozone is formed is through the high energy contained within electrical discharges. Have you ever noticed the clean, sweet smell after a thunderstorm? That refreshing smell is the result of ozone that is produced by the electrical discharges from lightning. In additional to its natural occurrences, ozone can also be reproduced scientifically in controlled quantities through corona discharge. By applying high voltage to a metallic grid sandwiched between two dielectrics, ozone generators can produce safe amounts of ozone that can be used to eliminate contaminants.
How Does It Work?
As mentioned, ozone contains a highly unstable third oxygen atom. When ozone gas is introduced to an environment with any organic contaminants, it gives off its third oxygen atom to oxidize them. This atom attaches to the contaminants and eliminates everything in the air, leaving only oxygen molecules. This is the major reason why ozone is preferred as an oxidant to other chemicals, because it does not leave any type of residual chemical. The only byproduct of ozone oxidation is clean, fresh air!
How Does Ozonating Food Extend Shelf Life? June 22 2017, 0 Comments
With the recent focus on healthy eating and living, there has been an increase in consumer demand for fresh produce. The shelf-life of fresh fruits and vegetables, however, is relatively short and is limited by the loss of textural, visual, and nutritional quality. Although chemicals such as chlorine may seem to preserve the quality of fresh produce, the side effects of these treatments ultimately cause more harm than good. So what is the safest and most effective way to keep your fruits and vegetables fresh? Let’s look at how the use of ozone can extend shelf life.
How it Works
Ozone (O3) is a form of oxygen that has an additional oxygen atom. The oxidizing power of ozone is derived from this third atom which is extremely unstable. With an oxidizing power that is 3,000 times more effective than bleach, ozone is the strongest natural oxidant for sanitation and disinfection. When ozone is introduced to contaminants such as mold and bacteria, it gives off its unstable oxygen atom which combines with organic and inorganic molecules to eliminate them through a process called oxidation.
Since ozone oxidation is a natural process, it is both safe and reliable. Studies show that ozone can effectively eliminate 99.9% of bacteria and viruses found on food products, therefore, extending shelf life significantly. In addition to its strong disinfecting mechanisms, the use of ozone is also environmentally friendly and cost-effective.
Myths About Ozone Generators June 20 2017, 0 Comments
Ozone is a chemical compound that has the power to oxidize just about everything, except large particles. Below, we bust common myths about ozone generators.
Myth: Any air ozone generator will kill mold and mildew, and remove smoke damage out of a room or home.
False, this statement just isn’t true. The ozone generator must produce at least 7,000 mg per hour for it to work on these tough complaints. A lighter weight machine will freshen the air temporarily, not eradicate mold spores. The A7K is the most powerful air unit produced by A2Z Ozone, Inc. at 7,000 mg/hr.
Myth: One treatment with an air ozone generator will keep mold and mildew away.
Sometimes more than one treatment is needed, depending on the infestation.
We recommend treating a room gradually, until you reach the needed amount of time. Below is a chart that demonstrates this:
Myth: It is safe to be in the room with a 3,000-mg ozone generator.
False, ozone generators should be used in unoccupied areas. We recommend the three P’s: no People, Pets, or Plants.However, weaker units like the Aqua-6 (600 mg/hr) are safe to be around. Exposure to too much ozone can cause permanent damage to your lungs.
Our in-home generators are designed to produce just the right amount of ozone to effectively sanitize your water and air, but not strong enough to exceed recommended EPA levels. The current EPA standard for in-air ozone is .05 ppm. Ozone also has a 20-30 minute half-life in the air meaning that its concentration will break down quickly.
Myth: Ozone is safe for all the materials in my pool.
False, ozone is capable of breaking down some materials. To be safe, you must ensure that all your equipment is ozone resistant. Read the chart below to determine if your materials are ozone resistant.

How Ozone Can Improve Your Breakfast - A2Z Ozone, Inc.
Do you wake up on some mornings thinking about what to eat for breakfast? You need something healthy or maybe you are someone who regularly loves fresh fruit or vegetables in the morning. Some daily issues we are faced with is cost and shelf life of our fresh produce. Some produce stays fresh longer than a cup of raspberries, and some of us that enjoy these with cereal or pancakes frequently, find that it can’t stay fresh a long time. Buying in bulk is not a good option in some cases.
Maybe you heard of ozone treatment or currently use an ozone generator to wash your produce. It is not only extending shelf life up to three weeks on some produce depending on conditions and storage, but it removes bacteria, viruses, E. coli, and your fruits and vegetables taste fresh. “Research and commercial applications have indicated that ozone can replace chlorine with more benefits. In 1997, ozone was self-affirmed as Generally Recognized As Safe (GRAS) as a disinfectant for foods by an independent panel of experts sponsored by EPRI. This self-affirmation was timely for the produce industry in light of the President’s Fruit and Vegetable Safety Initiative. The produce industry is successfully using ozone all over the world.” (Ozone Safe Food Technologies, Inc.) In 2000, FDA and USDA approval was granted.
To treat your produce with ozone, fill your sink with water and place the Aqua-6 diffuser stone 2 to 4 inches deep in sink. Place the fruit and/or vegetables to be treated in the water and operate the Aqua-6 for 15 minutes by selecting Function #4 (Average sized sinks should be half-full). Follow the same procedure above to wash your raw food and meat. For utensils, rinse off food debris and treat in clean water with ozone for 15 minutes. Our Aqua-6 Multi Purpose Ozone Generator is our best seller and practical to use for many other applications like ozonating drinking water, dental hygiene, odor removal, and making natural liquid oil. It can be used with fish tank, spas, hot tubs, and wading pools up to 500 gallons.
