The ability of activated carbon to reduce total organic carbon in highly concentrated wastewaters from a coal gasification pilot plant was evaluated in laboratory batch and column tests. The wastewater initially contains over 5000 mg/l TOC, largely phenols and cresols, with numerous other organic species in much lower concentrations. The physical adsorption process is best explained by the Freundlich model, with the slope and intercept of the Freundlich isotherm comparable to data reported for treatment of refinery wastes. Carbon exhaustion rates and bed depth-service time curves are also comparable to refinery treatment data obtained from waters of lower TOC or COD. Laboratory-scale column tests reduced TOC from 5740 mg/l to 200 mg/l.
