Abstract: The feasibility of micellar-enhanced ultrafiltration (MEUF) for separation of volatile organic compound (VOC) was investigated. Cationic surfactant, cetylpyridinium chloride (CPC) was used for the formation of micelles. The VOCs selected were an lonic compound (phenol)nd a non-ionic compound (toluene). The experiments were carried out by a flat sheet UF module using cellulose acetate membrane with MWCO 10,0000. MEUF experiments were divided into two systems: single organic-CPC and binary organics-CPC systems. The results showed that flux increased with increasing applied pressure and flow rate for single organic-CPC system, but the presence of CPC reduced flux in both phenol-CPC and toluene-CPC system were observed to increase with increasing CPC concentration. In phenol-toluene-CPC system. It appeared that flux decreased with increasing CPC concentration. But the rejection of phenol was increased by the presence of toluene while the rejection f toluene was not affected by phenol. The extent of solubilization decreased with an increasing concentration of both phenol and toluene. Solubilization of toluene in CPC micelles was more than that of phenol, therefore, toluene rejection was higher than phenol rejection
