Impacts of assimilable organic carbon during the coagulation by aluminum in drinking water
(0) The variation of Assimilable Organic Carbon (AOC) during the coagulation of raw surface water and synthetic water by Al2(SO4)3 was investigated. It was found that the removal rate of AOC concentration during alum coagulation of raw surface water was about 49.5％ at high coagulant dosages. The AOC of water decreased efficiently during coagulation in the case of synthetic water at lower coagulant dosages, and the lowest value of AOC achieved was 186 μg·L-1.The results showed a relationship between the solution pH and the reduction of AOC. The performance of coagulation effect was evaluated based on the following parameters: pH, turbidity, UV absorbance at 254 nm (UV254), and Total Organic Carbon (TOC). The results showed that the coagulation performance have substantial impact on AOC reduction.
