Abstract

Traditional bioprocesses have difficulty treating biorefractory org. pollutants in wastewater which contains high concns. of inorgs. A novel hybrid process, combining liq.-liq. extn. and a membrane bioreactor was designed to treat such wastewater. To demonstrate the effectiveness of this process, a synthetic wastewater was designed to represent the type of effluent which often results from the specialty org. chems. sector. This model effluent contained high concns. of chlorophenols (CP) (1000 mg/L), salts (15% wt./wt.), and had a pH
