Ozonia specializes in manufacturing systems that deliver ozone, ultraviolet (UV) and advanced oxidation process (AOP) technologies in the municipal, industrial and leisure markets.

The Contra Costa Water Treatment Plant in San Francisco (200 kg O3/h) illustrated the ability to produce higher concentration ozone while reducing oxygen consumption.

[4] 1996 To satisfy the rapidly growing Asian market, Ozonia opened an office in Seongnam City, South Korea, after acquiring a majority stake in "CHAMP Ozone".

Ozonia expanded its presence to seven countries: Switzerland, France, United States, Great Britain, Russia, South Korea and Japan.

The department showcased Ozonia's knowledge in various applications including pulp bleaching, wastewater and aquaculture, with a goal to better educate clients.

The new facility increased production capacity and efficiency, and improved the quality and the ability to engineer project specific equipment.

The new center is a major milestone that allows Ozonia to design and manufactures ozone generators locally that address the Chinese market.

Ozonia manufactures ozone, ultraviolet (UV) and advanced oxidation process (AOP) technologies and systems for water treatment.

UV disinfection is environmentally safe and recognized as highly effective on inactivating a wide range of pathogens, including viruses, bacteria and parasites.

[8] UV also covers a number of applications: drinking water, food and beverage, aquaculture, power generation, cooling water microelectronics, pharmaceutical, wastewater disinfection, reuse wastewater, combined sewer overflows (CSO) & sanitary sewer overflows (SSO).

Main advantages of UV disinfection are such as short contact times for pathogens to be inactivated and effectiveness on protozoa cysts and other chlorine resistant organisms.

AOPs further improve chemical oxidation processes by combining three proven treatment technologies – ozone, UV and hydrogen peroxide – to create in-situ highly reactive hydroxyl radicals (.OH) for elimination of organic pollutants.

Due to industrial and demographic pressures, the use of AOP in water treatment is expanding for a number of critical uses including the oxidation or removal of industrial chemicals, pharmaceuticals, endocrine disrupting compounds (EDC's), personal care products (PCP's), pesticides, toxic compounds, pathogens, persistent organic matter, and odor, color and taste.

Suez Environnement S.A. (Euronext: SEV) is a French-based utility company which operates largely in the water treatment and waste management sectors.
