Disinfection

Disinfection is a two-step process. Liquid bleach (sodium hypochlorite) is added to the wastewater which kills any remaining pathogens or disease-carrying organisms. The chlorine-containing water remains in the last set of holding tanks at the plant for about two hours. The water is then dechlorinated (with sodium bisulfite) to protect fish and other aquatic wildlife. The treated water is then reclaimed or discharged to the LA River.
