The main purpose of the ozone generator in the water treatment plant is to make sure that the water is bacteria and viruses free and volatile organic and possibly toxic compounds have been destroyed in the water.
Full Answer
What is ozone and how does it work?
When dissolve in water, Ozone is an oxidant with extremely superior performance. It can oxidatively decompose the difficult-to-degrade organic matter in the water body, and cooperate with other processes to achieve advanced treatment of wastewater.
What is the difference between ozone and chlorine?
Ozone and chlorine are often compared because both have strong disinfectant properties, but they differ in speed, chemical presence, and overall effectiveness. Ozone water treatment systems disinfect water about three times faster than chlorination and require a shorter contact time with water to be effective.
How is ozone water treated?
While closer to the surface, ozone is created when lightning strikes and electricity cuts through oxygen rich air. Both processes are mimicked in ultraviolet and electrical ozone generators, which make ozone water treatment possible.
What is ozonation in water treatment?
Ozone water treatment requires no additional chemicals to be added to the water during treatment. The treatment removes many impurities from the water as well as odor and taste. Compared to chlorine, ozonation is considered to be more effective than chlorination regardless of the pH level of the water.
What is ozone water treatment?
Ozone water treatment is used in commercial, industrial, and municipal water treatment systems, as well as in home systems. Major beverage companies rely on ozone water treatment technology and it is often used to disinfect bottled water. Ozone is also employed by cities to treat and disinfect municipal water supplies.
What is the role of ozone in the atmosphere?
In the upper atmosphere, ozone filters the sun’s ultraviolet light and protects earth from harmful radiation, but here on the surface, ozone plays a role in ensuring clean drinking water ...
How are chlorine and ozone different?
Ozone and chlorine are often compared because both have strong disinfectant properties, but they differ in speed, chemical presence, and overall effectiveness. Ozone water treatment systems disinfect water about three times faster than chlorination and require a shorter contact time with water to be effective.
How does ozone water work?
Ozone water treatment begins with the creation of ozone in an ozone generator. Then, ozone is injected into water, and immediately starts oxidizing and eliminating contaminants, such as bacteria, viruses, and metals. Ozone oxidizes organic material in the membranes of bacteria, viruses, and parasites. This weakens, ruptures, and kills their cells, ...
How is ozone produced in a UV light?
In a UV ozone generator, ozone is produced as oxygen is passed between the lamp and the quartz sleeve of a UV light. The ozone is then drawn into water using a venturi and the water treatment process begins. However, UV ozone generators are not as powerful as electrical ozone generators and produce ozone at lower concentrations.
What are the disadvantages of ozone water treatment?
1. Cost. Ozone water treatment is expensive compared to more well-known water treatment methods, such as chlorination. It has high equipment and operational costs, and it may be difficult to find a professional who is proficient in ozone water treatment.
What is the most common way to treat water?
Ozone can also be produced by electrolytic and chemical reactions, but UV and electrical ozone generators are the most common for water treatment.
