Modeling decay of chloramines residuals by copper pipe distribution test loop system;

Combined pretreatment of potassium permanganate and chloramines to control trihalomethane formation;

The inactivation effects of humic acid and lactose peptone culture solution content are inspected with individual application process of chlorine, chloramines and potassium permanganate, and with combined application process of potassium permanganate with chlorine or chloramines.

Control of disinfection by-products in drinking water by monochloramine disinfectant;

Decreasing the ratio of chlorine to ammonia to 5 can reduce DBPs by 89 percent and no dibromochloromethane was detected;the amount of DBPs had a good pertinence to the monochloramine dose;contact time had little effect on DBPs,and DBPs had little slow increase after 24 hours;increasing pH value to 8 can decrease DBPs by 82.

The inactivation of Escherichia coli with free chlorine and monochloramine was studied using bench-scale experiments in 0.

It is based on the iodine catalysed discoloring reaction of malachite green oxidized by chloramine T in hydrochloric acid medium.

Effect of Chloramine Disinfection on the Formation of Drinking Water Disinfection By-Products and Their Muta-genicity;

Characters of natrural organic matters in south water resource and the control of DBPs by chloramine compared with chlorine;

Controlling HAAs yields in chlorine/chloramine disinfection by potassium permanganate preoxidation;
