摘要：An experimental study has been carried out in an attempt to verify the efficiency of GAC (granular activated carbon) in removing THMs (trihalomethanes), and in particular CHCl3, CHCl2Br, CHClBr2 and CHBr3 from drinking water. The experiments have been conducted at a pilot scale filtering plant that was set up for the purpose, at the Athens Water Authority, at Galatsi. This paper reports on the experimental procedure, the sampling technique, the analytical method used, the overall efficiency of the approach and finally also draws some first conclusions as to the economic justification of the method, in order to provide some insight on the additional costs of a possible fullscale use of the method.
