| Abstract |
Trihalomethanes(THMs) are formed with the reaction of natural organic matter when chlorine is added as disinfectant in water treatment plant. This study was designed to evaluate the removal efficiency of THMs formation in the conventional water treatment plant with the use of Jar test simulation. The characteristics of THMs formation in each unit process of the K water treatment plant were presented. The formation of THMs in water treatment plant was predominant in the rapid mixing chamber and flocculation basin, and the relative ratio of THMs formation in the rapid mixing chamber and flocculation to that in settling basin ranged from 3.3 to 22.3. The estimated removal efficiency of THMs with Jar test results was 33∼58% which may be interpreted as that much of THMs formation precursor could be removed out in the conventional water treatment process. The aspect of the potential effectiveness of the conventional water treatment process for the control of disinfection by products may be considered in introducing the advanced water treatment process in the conventional water treatment plant. Chloroform was the most dominant species in THMs and Bromodichloromethane comprises of l/5 of the total THMs. |
