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
