Bromates are known to be formed when there is bromine dissolved in water and high levels of ozone as well as high pressure tank contact systems are used to disinfect it. They are undesireable byproducts because they are known to be carcinogenic. Sodium bromate is a strong oxidant, mainly used as printing and dyeing auxiliary, hair-permagent, chemical agent, or gold solvent in gold mines when used with sodium bromide. ... Potassium bromate has formula KBrO3. ... In pathology, a carcinogen is any substance or agent that promotes cancer. ...
The International Ozone Association has made public their research on the subject and has given several proposals to avoid bromate formation, which include switching to atmospheric tank contact systems, lowering the water pH to between 5.9-6.3, and limiting the doses of ozone.
Ozono Polaris has developed the technology, which does all this, and has successfully installed more than 10 of such systems to the Coca-Cola Company.
