Dechlorination | Chlorine | Chloramines - Process Water

Most U.S. public water supplies today are disinfected with either chlorine or chloramines (chlorine mixed with ammonia). For disinfection, chlorine is generally added as a gas or liquid (typically as sodium hypochlorite) to produce a free chlorine residual of 0.5 parts per million (ppm) to 2.0 ppm. Unfortunately, chlorine and its related compounds are oxidizing agents and can have harmful ...
