THMs Formation and Its Characteristics in Finished Drinking Water of K Water Purification Plant in Kunsan |
| Abstract |
This study was performed to survey trihalomethane (THMs) formation levels in finished drinking water produced in K water purification plant and to examine its characteristics according to the application of GAC treatment process. During period before the application of GAC treatment process, total THMs formation level was highest in August, seasonally, in summer. It was decreased by GAC treatment significantly, but the average reduction efficiency of THMs formation was decreased with the lapse of operation time of GAC process, when THMs formation was compared with that before the application of GAC treatment. The ratio of CHCl₃ among total THMs was decreased from the 5th month after the application of GAC process, indicating the increased formation of Br-substituent, especially CHClBr₂ and CHBr₃, by GAC treatment Of the water parameters examined, water temperature showed the strongest correlation with THMs formation. |
