Disinfection of drinking water by chlorination process, produces Trihalomethanes (THMs) which
are believed to be carcinogenic. The adsorption onto Granular Activated Carbon effectively
removes THMs from drinking water. In this research, we studied the adsorption characteristics of
THMs onto GAC in different contact time and at 15 and 25 ºC. On the basis of these studies,
various parameters such as surface mass transfer coefficient and effective diffusion coefficient of
THMs onto GAC were evaluated. It was concluded that the temperature increase, will rise the
effective diffusion coefficient while surface mass transfer coefficient will be reduced.
