%X Two-points-short-term free chlorine plus chloramines disinfection process was used in conventional treatments of water supply. The process is adding chlorine at the start of filtration and clear well respectively, and then after a few minutes chlorine disinfection in clear well adding ammonia to change the chlorine to chloramines. The point of chlorine dosing move up to the filtration process can decrease disinfection by-product yield and control bio-film growth in filtration process. Compared with adding equal quantity chlorine once, this process reduced 51.6% of THMs and 46.7% of HAAs. HPC result also showed advantage in microorganism controlling.
