Equal-sized activated carbon and anthracite coal were compared when used as packing media in completely mixed anaerobic filters. Synthetic glucose and phenol bearing solutions and a diluted paint stripping bath wastewater were used as the test substrated. Each wastewater was fed to the two anaerobic filters until stable operating conditions were reached. The granular activated carbon packed filter resulted in better chemical oxygen demand conversion, higher rates of methane production, and lower biomass production than the anthracite packed filter for all the conditions tested.
