Abstract

The micropollutant adsorption out of ground and surface waters is difficult to describe theoretically due to the partly non-ideal adsorption behavior of natural organic substances as, e.g., irreversible adsorption. Based on practical results over the past few years, simplified methods have been developed to describe the micropollutant adsorption in powdered and granular activated carbon treatment plants. These methods have led to the design of activated carbon treatment plants and predictions for the carbon efficiency in the event of changing raw water quality.
