EVALUATION OF CHLORITE AND CHLORATE PROPAGATION IN A DRINKING WATER DISTRIBUTION SYSTEM

摘要

Disinfection is applied in drinking water treatment plants (DWTPs) to ensure water quality and to avoid bacterial contamination in drinking water distribution systems (DWDSs). However, disinfectant concentration in DWDSs decreases with time, while disinfection byproduct (DBP) formation increases; this is due to chemical reactions of the disinfectant with dissolved and particulate matter in the water, biofilm and pipe wall material.
