This paper reports the treatment of oil-bearing wastewater by polysulfone-alumina composite membrane w hich have been produced by the addition of Al2O3 to polysulfone(PSF).After the change of the permeate flux along with time and pressure is measured and the water sample is analy sed,the composite membrane are found to be very ef fective fo rremoving oil from oil-bearing wastewater.The permeation flux of the composi temembrane still keeps 85 % the first fluxafter sixth cleaning,the treated water samples conform to application request in oil field.
