The objectives of this study were implemented to investigate the haloacetic acids formation potential (HAAFP) in drinking water treatment and determine the reduction of haloacetic acids (HAAs) during preozonation. This full-scale examination was conducted with Luan River water. Two preoxidation methods were performed, prechlorination and preozonation. HAAFP and HAA species were analyzed. The investigation indicated that 33.25% of HAAFP was removed during preozonation. Study on the distribution of HAA species showed a significant reduction during preozonation, 21.52% of DCAA, 66.20% of TCAA and 42.59% of DBAA was removed, respectively. The result suggested that preozonation process is effective to reduce HAAs generation during the treatment. In the final effluent, the total removal rate of HAAFP was 67.79%.
