Title: Control of Disinfection Byproducts in Safe-chlorine- disinfection Process
Abstract: Pilot-scale test was carried out for the new type combined chlorine disinfection—short-term free chlorine plus chloramines disinfection process in a water treatment plant in Tianjin.The result shows that in the case of the same influent,trihalomethane and haloacetic acid produced in the safe-chlorine-disinfection process are respectively 35.8%-77.0% and 36.6%-54.8% lower than those in conventional free chlorine disinfection process.The poorer influent quality in disinfection contact tank results in the more advantages of the short-term free chlorine plus chloramines disinfection process in the control of disinfection byproducts.In the test,formation characteristics of disinfection byproducts is observed in raw water with higher bromide ion concentration.
