The Contra Costa Water Treatment Plant in San Francisco (200 kg O 3 /h) illustrated the ability to produce higher concentration ozone while reducing oxygen consumption. 1993 Ozonia North America was founded after Ozonia AG acquired "Griffin". The new American subsidiary manufactured ozone generators compliant with the North American standards.
For water treatment, CWTP utilizes four ozone generators, designed to handle an average capacity of 275 million US gallons (1,040 million litres) per day—although average daily consumption is lower, at approximately 200 million US gallons (760 million litres)—and a peak level of 405 million US gallons (1,530 million litres) per day.

Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in Nice, France. The U.S. Food and Drug Administration has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods.
In real-world applications of wastewater treatment, however, this term usually refers more specifically to a subset of such chemical processes that employ ozone (O 3), hydrogen peroxide (H 2 O 2) and UV light [2] or a combination of the few processes.
Dalecarlia Water Treatment Plant, Washington, D.C. Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.
The plant used a combination of ozoflotation with filtration. It proved to be successful in treating algal growth which causes taste and odour problems. The success led to the construction of a larger scale plant at Kempton Park water treatment works. [8] In 1992 Thames Water installed a 1.4 Ml/day pilot plant at Kempton Water Treatment Centre. [7]
If you’re not familiar with water ozone generators, you’re not alone. While these can be pretty common in industries like cleaning, sanitation, flood restoration, and fire departments, for ...
Eradicate water-borne parasites such as Giardia lamblia and Cryptosporidium in surface water treatment plants. Ozone is a reagent in many organic reactions in the laboratory and in industry. Ozonolysis is the cleavage of an alkene to carbonyl compounds.
