Abstract

Objective To investigate the feasibility of reducing THM precursors and controlling bromate taste and odor in drinking water taken from the Yellow River by an ozonation combined system. Methods The appropriate ozone dosage was determined,and then the changes of TOC,UV254 and THM formation potential(THMFP)in the combined system were evaluated. Results One mg/L ozone could effectively remove taste and odor and meet the maximum allowable bromate level in drinking water.The pre-ozonation increased THMFP,but the conventional treatment system could effectively reduce the odor.The bio-ceramic filter could partly reduce CHCI3FP,but sometimes might increase CHCI2BrFP and CHCIBr2FP.The biological activated carbon(BAC)filter could effectively reduce CHCI3FP and CHCI2BrFP,but increase CHCIBr2FP.Compared with other filters.the fresh activated carbon(FAC)filter performed better in reducing THMFP and even reduced CHCIBrzFP.Conclusion The combined system can effectively reduce taste,odor,CHCI3FP,and CHCI2BrFP and also bring bromate under control.
