Phenolic compounds are the primary wastewater treatment challenge found in the aqueous effluents from petroleum refineries, coal conversion processes, petrochemical pro- duction, and the manufacture of phenols and related chemi- cals. Emulsion liquid membrane (ELM) separations are a developing technology with high potential for cost-effective removal and recovery of phenolic compounds. Unlike cur- rent treatment technologies, ELM processes can almost completely remove phenolics, both high and low concentra- tion feed streams, while producing a concentrated solute level in the stripping phase, simplifying final recovery. Further, ELM offers independent control over the solvent operating characteristics and affinity for phenol, allowing the design of a much less expensive process. The objective of the proposed research program is to evaluate the technical and economic feasibility of the ELM process for treatment of industrial wastewater streams. The final result of the two-phase research project will be a pilot-scale unit oper- ating on actual phenolic wastewaters to determine the operating characteristics of the system and accurately esti- mate the process economics.
