Does chlorine dioxide produce byproducts?
Pure chlorine dioxide gas that is applied to water produces less disinfection byproducts than oxidators, such as chlorine. Contrary to ozone (O3), pure chlorine dioxide does not produce bromide (Br-) ions into bromate ions (BrO3-), unless it undergoes photolysis. Additionally chlorine dioxide does not produce large amounts of aldehydes, ketons, keton acids or other disinfection byproducts that originate from the ozonization of organic substances.
