| Abstract: | Two processes in the pilot plant were studied and compared to reduce the disinfection byproduct risk of the potable finished water of Feng-shan treatment utility in Taiwan. For 5 months study, two processes have both demonstrated to achieve a significant removal on the organic precursors of DBPs, including NPDOC and A-254. With the analysis of molecular weight distribution of organics in raw water, the study found the post ozonation plus BAC can provide additional enhancement in degrading organic contents. A process of coagulation/sedimentation/rapid sand filtration/post ozonation/BAC would be suggested as the advanced treatment process improving the supply quality of Feng-shan utility. |
