영문 초록

The ability of domestic GAC to remove THMs from treated drinking water was evaluated in pilot column test. GAC column was installed in C water purification plant located in K city and operated for 23 weeks under the given conditions(volumetric flow rate: 120㎥/hr, linear velocity: 6m/hr, EBCT: 15 min). From the breakthrough curve, domestic GAC showed more than 95% of removal efficiency of THMs until 4 weeks after operation, and maintained 90% level until 10 weeks and 80% level until 14 weeks after operation. It showed higher removal efficiency for CHChBr than for CHCl₃. Of the measurements related to organic compounds, KMn04 consumption showed the highest correlation(r²= 0.940) with THMs removal by GAC adsorption. The r² values for TOC and UV{_254} were 0.592 and 0.381, respectively.
