dc.description.abstract | This research studied the effect of factors that are able to form disinfection by-products (DBPs) of chlorination, including natural organic matter (NOM) with sewage, bromide ions, pH and contact time. Trihalomethane (THMs) yield of 0.95 μmol/㎎ was higher than other DBPs yield for the chlorinated humic acid samples. THMs yield of sewage sample was 0.14 μmol/㎎ and haloacetonitriles (HANs) yield in the sewage samples were 0.13 μmol/㎎ but only 0.02 μmol/㎎ for the humic acid samples. As the concentration of bromide ions increased, brominated DBPs increased while chlorinated DBPs decreased, because bromide ions produce brominated DBPs. THMs were highest (55.55 ㎍/L) at a pH of 7.9 and haloacetic acids (HAAs) were highest (34.98 ㎍/L) at a pH of 5. Also THMs increased with increasing pH while HAAs decreased with increasing pH. After chlorination, the rate of THMs and HAA formation are faster at initial contact time and then reaches a nearly constant value after 24 hours. This study considers ways to reduce DBP formation by chlorination. | - |
