1. - Background: Chlorine Dioxide (ClO2) is an extremely powerful oxidant that can be used to improve the aesthetic, chemical, and microbiological quality of drinking water. Chlorine Dioxide generator using Chlorine gas and Sodium Chlorite under vacuum. The proper use of ClO2 can reduce the taste and odor complaints, improve iron and hydrogen sulfide concentrations, and improve the coagulation process at the surface water treatment plant. It does not form halogenated disinfection by-products such as trihalomethanes and haloacetic acids and is a very effective disinfectant. However, elevated levels of ClO2 and its principal by-product, chlorite, can have their own adverse health effects. Consequently, the Texas Commission on Environmental Quality (TCEQ) recommends that only well-operated, high efficiency ClO2 generators are utilized by public water systems.

2. - References: Industry leader in chemical generation of Chlorine Dioxide applications.
