| Abstract |
| The objective of this study was to investigate the effects of chlorination and powered activated carbon (PAC) on volatile organic compounds (VOCs) removal in the river water using as a drinking water source. Batch and column tests were carried out with artificial water. Chlorine dose was set to 2, 5, 10, and 15mg/L at contact time of 1h and PAC dose was set to 2, 4, 6, 8, and 10mg/L at contact time of 30min. As a result, chlorination achieved the highest removal for 11-dechloroethylene in raw water with low concentration corresponding to the river water quality and for carbon tetrachloride in the water with high concentration corresponding to about 10 times higher than that of the river water. On the other hand, PAC adsorption achieved the highest removal for xylene regardless of VOCs concentration in the raw water. Thus chlorination was ineffective in reducing VOCs while the removal efficiency of PAC adsorption was about 2 times higher than that of chlorination. |
