Although the phenomenon of the formation of trihalomethanes during the disinfection of drinking water with free chlorine has been known for over ten years, water utilities are still seeking effective methods of control, while maintaining good disinfection. The brief study was conducted to determine the feasibility of a new approach to trihalomethane control. Reports in the literature state that predominantly bromine-substituted trihalomethanes are adsorbed on activated carbon better than predominantly chlorine-substituted trihalomethanes. The goal of the proposed treatment scheme, therefore, was to minimize the concentration of trihalomethanes in finished water by the addition of bromide to water to deliberately create predominately bromine-substituted trihalomethanes, that could subsequently be removed by powdered activated carbon.
