Chlorine Dioxide for Wastewater Treatment

Wastewater Deodorization

The formation of hydrogen sulfide often poses a problem for municipal wastewater treatment. DuPont™ Endimal®, a powerful deodorizing 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 the U.S. EPA Office of Drinking Water.

Lift Stations

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