Most disinfection byproducts(DBPs) in water treatment process are formed by means of a pretreatment step such as the prechlorination and preozonation. Recently, it needs much research for a bromide substitution reaction in the DBPs because the enhancing water quality standard about bromine DBPs. And There is the difference in the formation characteristics of bromine compounds in trihalomethans(THMs) and haloaceticacids(HAAs). So, this study was performed to investigate the THMs and HAAs in the chlorinated DBPs for the influence of the DBPs formation according to variation of raw water characteristics, water temperatures and concentrations of disinfectants and coagulants. As a result, the concentrations of CHBrCl2 in the THMs was higher with a decrease in water temperature. However CHCl3 was higher with an increase in water temperature at the pretreatment. In HAAs, tricholoacetic acid(TCAA) was formed the more than dicholoacetic acid(DCAA) with an increase in water temperature. Bromine incorporation factor(BIF) of THMs and HAAs was affected by water temperature but it was not affected by a species and amount of the aluminum coagulant. Also, the BIF of the HAAs was affected the more by a specific ultraviolet absorbance(SUVA) than water temperature.
