What is Chlorine Dioxide?
Chlorine Dioxide (ClO2) is a stable, dissolved gas considered to be a strong bactericide and virucide at concentrations as low as 0.1 ppm. With minimal contact time, it is highly effective against pathogenic organisms such as Legionella, amoebal cysts, Giardia cysts, E. Coli, and Cryptosporidium. ClO2 is also known to reduce biofilms so bacterial regrowth is significantly impeded and does not ionize to form weak acids (as chlorine and bromine do) in aqueous solutions. This allows ClO2 to be effective over a wide pH range. ClO2 is arguably the best biocide approved by the United States Environmental Protection Agency (USEPA) and Food and Drug Administration (FDA). Unlike chlorine, it does not form carcinogenic disinfectant by-products (THMs and HAAs), and it is more effective at lower dosing levels.
