Abstract: The rapid increase of oily wastewater production from both industry process and daily life has highlighted the worldwide challenge to separate oil water mixtures,especially oil/water emulsions. With respect to high separation efficiency and simple operation process,membrane separation has been acknowledged as an advanced technology for treating oily wastewater. This paper introduces recent progress in developing advanced membranes with high flux,high selectivity and anti-fouling properties for effectively treating oily wastewater,including traditional polymer-dominated and ceramic-based filtration membranes,as well as recently developed nanomaterial-based functional filtration membranes. The separation efficiency and anti-fouling properties of different type membranes are described and compared in details. Finally,the remaining challenges and future directions for developing high performance oil-water separation membrane are proposed.

Key words: oily wastewater, separation, membrane, anti-fouling, nanomaterials
