In order to comply with the trihalomethane regulation, many drinking water utilities have had to alter their treatment methods. ne option available to these utilities is to use a disinfectant other than chlorine such as chlorine dioxide. ith chlorine dioxide disinfection, trihalomethanes are not formed by reactions with humic substances if the chlorine dioxide is produced without excess chlorine. lso, chlorine dioxide is not expected to react with humic substances to form other byproducts scheduled for regulation such as haloacids and haloacetonitriles. owever, there are some possible health effects from chlorine dioxide and its inorganic byproducts (chlorite and chlorate). hlorine dioxide has been used in potable water treatment for controlling taste and odor and for removing iron and manganese. or control of bacteria and viruses, chlorine dioxide is as effective or superior to free chlorine. hlorine dioxide is an effective drinking water disinfectant and current estimates indicate that 300 to 400 utilities in the United States have chlorine dioxide treatment equipment. his paper presents the methods of generation, biocidal effectiveness, field applications, and problems with using chlorine dioxide for disinfecting drinking water.
