DuPont Chlorine Dioxide

Chlorine dioxide for municipal wastewater treatment industry - Water and Wastewater

Wastewater Deodorization: The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment.  Chlorine dioxide, a powerful oxidant, can be effectively used to control noxious, irritating, or pungent odors from many operations.  Moreover, its unique selective properties permit more efficient application at a lower dosage and cost than chorine, hypochlorite, permanganate peroxide or ozone.

Wastewater Disinfection

Chlorine dioxide’s effectiveness is not limited to just odor-related problems.  When used in water disinfection, it does not form chlorinated or brominated by-products, such as trihalomethanes (THMs) or haloacetic acids (HAAs), both of which cause concern for health and will soon come under strict regulatory limits.  Use of chlorine dioxide as a disinfectant is already approved and used by EPA's Office of Drinking Water.

Lift Stations

Endimal® chlorine dioxide compound effectively addresses lift station odor complaints from neighboring communities and improves workspace air quality for employees.  It also reduces hydrogen sulfide corrosion problems.
