| Abstract |
This study was carried out to investigate the formation of DBPs(Disinfection By-products) such as trihalomethane(THMs) and haloacetic acid(HAAs) by chlorination in raw water and finished water of Water Treatment Plant(WTP). The formation of THMs was increased with the increase of pH and reaction time. HAAs was found as a high formation at a pH 7 and low formation pH 9/ THMFP(Trihalomethane Formation Potential) was the highest formation potential in raw water of Pu-1 and the lowest in raw water of Pa-1. In case of HAAFP(Haloacetic acid formation potential), So-1 showed the highest value, while Pa-1 showed the lowest value. It was investigated the relationship between HAAs and organic matters which were described as DOC(dissolved organic carbon) and UV_(254). In both DOC and UV_(254) versus HAAFP, Pu-1 showed the good correlation coefficients(r²) with 0.95 and 0.84, respectively. For three WTP investigated, DBPs(THMs+HAAs) was shown over the range of 42.00∼49.36㎍/L. This result might be due to different characteristic of organic matters in raw water and the difference of chlorine dosage for a water treatment. |
