  • Activated carbon treatment of oxygenated wastewater
    Patent number: 4080287
    Abstract: An integrated system for treating wastewater containing biodegradeable organic contaminants by oxygenation thereof in the presence of activated sludge in an enclosed oxygenation zone with at least 50% oxygen feed gas and removal of the residual organic contaminants by adsorption in an activated carbon adsorption zone. At least part of the oxygen-depleted vent gas discharged from the oxygenation zone is concurrently flowed upwardly through the adsorption zone with the oxygenated effluent to maintain aerobic biological conditions in the adsorption zone for physical adsorption and biochemical oxidization of the residual organic contaminants therein.
