The adsorption process of dissolved organic matter (DOM) from natural water, using the commercial powdered activated carbon (PAC) Norit SA Super, was studied in two variants. In one of the variants adsorption was conducted as a separate process. In the second, adsorption onto PAC was regarded as a process that supports coagulation. In both instances the efficiency of organic matter removal was expressed as the ratio of dissolved organic carbon (DOC) concentration (persisting in the water upon the termination of the process) to the initial DOC concentration in raw water. Experimental results were used to derive parameters of empirical formulae describing the efficiency of DOM removal by PAC adsorption.
