| Abstract: | This research investigated the fate of organic pollutants in each unit of a full-scale O3-BAC (biological activated carbon) drinking water treatment plant with micro-polluted raw water under different temperatures. Total organic matters were largely removed with low DBPs (disinfection by-products) formed. Large molecules were broken into smaller ones by O3 and middle-sized ones totally removed. Concentration of polysaccharide decreased except under high temperature. Small molecule contaminant species of refractory industrial additives, hydrocarbons, aromatics, herbicides, possible DBPs, etc., were detected. Some species passed through treatment process, some were removed and also new species formed. |
