Chlorine Dioxide is a powerful disinfectant and oxidizing agent. It has been used for many years in water treatment systems for the elimination of chlorophenols, the oxidation of inorganic compounds such as iron and manganese, and in the control of taste, odor, and color. Chlorine Dioxide is recognized by the EPA as a primary disinfectant and is effective against viruses, bacteria, and protozoa, including the cysts of Giardia, the oocysts of Cryptosporidium, and Legionella.
Chlorine dioxide also prevents harmful environmental pollutants that can have adverse health effects. Unlike typical chlorine, it does not react with ammonia to form less-active chloramines. It will not form trihalomethanes (THMs) or other chlorinated organic compounds, nor will it react with the many impurities that normally consume chlorine.
Evoqua offers a broad range of chlorine dioxide generators, specialized chemical feed systems, and water treatment chemicals.
