Pilot studies were conducted on two activated carbon-based systems for meeting the effluent quality requirements of an oil refinery. Upgrading of activated sludge by addition of powdered activated carbon directly into aeration tank mixed liquor and tertiary treatment of activated sludge effluent by granular carbon adsorption were studied. Powdered carbon enhancement was found to be more cost-effective than granular carbon adsorption for all except the very highest effluent qualities. Effluent quality from the powdered carbon enhanced system was found to be dependent on mixed liquor carbon concentration as well as carbon surface area. An experimental high-surface-area carbon was the most effective. To achieve high mixed liquor carbon concentration and maintain cost-effectiveness, the process is operated at a high sludge age-100 days or more. With improvement in regeneration technology, the process would be even more cost competitive with granular carbon adsorption.
