Ozone generators, or ozonators, [133] ... Eradicate water-borne parasites such as Giardia lamblia and Cryptosporidium in surface water treatment plants. Ozone is a ...
The amount of ozone manufactured for use in the food and other industries is reflected in the considerable effort placed on producing it efficiently in high performance ozone generators. [17] Where non-targeted antibiotic action is required, such as in water purification, it is widely used.
Ozone generators are designed to produce ozone and are sometimes sold as whole-house air cleaners. Unlike ionizers, ozone generators are intended to produce significant amounts of ozone, a strong oxidant gas which can oxidize many other chemicals. The only safe use of ozone generators is in unoccupied rooms, utilising "shock treatment ...
However, the required concentrations are sufficiently toxic to humans and animals that the U.S. FDA declares that ozone has no place in medical treatment [10] and has taken action against businesses that offer ozone generators or ozone therapy to consumers. [11] Ozone is a highly toxic and extremely reactive gas. [12]
Ozonation also produces fewer disinfection by-products than chlorination. A disadvantage of ozone disinfection is the high cost of the ozone generation equipment and the requirements for special operators. Ozone sewage treatment requires the use of an ozone generator, which decontaminates the water as ozone bubbles percolate through the tank.
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.
