Microfiltration α-Al2O3 membranes with pore sizes of 0.46 μm, 0.67 μm, and 0.89 μm were tested. The oil-in-water emulsions comprised 1000 ppm ofdodecane in distilled water. Effects of operation parameters such as transmembrane pressure, cross-flow velocity, and feed concentration were examined on oil rejection as well as permeate flux. To recover the permeateflux, backflushing and chemical cleaning were applied. Typically, a membrane with pore size of 0.46 μm had rejection higher than 99% under 2.10 m/s cross-flow velocity and 0.10 MPa transmembrane pressure. %8 2000-12-01
