Many of the wastewater problems that raise havoc with conventional treatment can be managed using a combination of physical adsorption and biological assimilation. This type of system is based on the discovery that when large amounts of powdered activated carbon (up to 15 g/l) are added to the aeration basin of a conventional activated sludge plant, biological and physical treatment occur simultaneously: biodegradable pollutants are assimilated by the biological organisms, while non-biodegradables are adsorbed on the carbon. Further, the combination produces a synergistic resulttreatment performance exceeds that possible with either method used alone, or in series. High removals of BOD, COD and suspended solids; odor and color control; toxic removal; and nitrification are obtained. Where carbon dosage warrants reuse, the system is coupled with a carbon regeneration step to improve system cost effectiveness and eliminate secondary solids disposal.
