Swimming pool water needs to be disinfected to keep swimmer from infection caused by water-born pathogens. However, use of chlorine and other disinfectants such as ozone and electrolytic disinfectant for disinfecting swimming pool water create new potential risks by producing by-products during the disinfection process. This study was carried out to investigate the characteristics of formed in swimming pool water disinfection Three different disinfection technologies including chlorination, combined disinfection (ozone+chlorine), and electrolytic disinfection were applied and their DBPs were compared. The average concentrations of total trihalomethans (TTHMs) of technologies were 37.49 μg/L for electrolytic disinfection, 16.41 μg/L for chlorination and 7.37 μg/L for combined disinfection. The major TTHM compound was chloroform and its concentration was 16.41 μg/L (chlorination), 7.37 μg/L (combined disinfection) and 14.49 μg/L (electrolytic disinfection). Bromodichloromethan (BDCM), Dibromochloromethan (DBCM) and Bromoform (BF) were only detected in electrolytic disinfection. The average concentrations of Haloacetic acids (HAAs) was 226.82 μg/L for chlorination, 170.71 μg/L for electrolytic disinfection and 76.54 μg/L for combined disinfection. About 85 percent of total DBPs was HAAs consisting of Trichloroacetic acid (TCAA) and Dichloroacetic acid (DCAA). TCAA and DCAA accounted for 59% and 26% of total DBPs from chlorination, 53% and 30% from combined disinfection, 54% and 19% from electrolytic disinfection respectively. Also TTHMs accounted for 16% of DBPs from electrolytic disinfection, 6% from chlorination and 8% from combined disinfection respectively. Chloral hydrate (CH) and Haloacetonitriles (HANs) were not detected much : they were 6% and 2% of DBPs from chlorination, 4% and 2% from combined disinfection and 4% and 4% from electrolytic disinfection, respectively. The compositions of DBPs were similar in Three different disinfection technologies, its concentrations was related to organic matters
