Abstract:

Application development of sodium hypochlorite and chlorine dioxide in feedwater water disinfection process was summarized．Disinfection efficiency，safety，generation process and cost was compared between them as substitute for chlorine．The conclusions indicate that chlorine dioxide is more suitable to substitute for sodium hypochlorite in respect to disinfection effect，byproduct safety and algae and odor removing．Development and promotion of high purity chlorine dioxide generation process by chlorate is the developing direction in future．

Key words: feedwater treatment, disinfection, sodium hypochlorite, chlorine dioxide
