Forward osmosis (FO) technology has received wide attention because of its low energy consumption,contamination resistance and other advantages,and has achieved rapid development in recent years. This paper introduces the influence factors and concentration polarization during the FO process. Internal concentration polarization is an important factor affecting penetration efficiency of FO technology,and preparation of suitable membrane material is the key technology to improve internal concentration polarization .The development of forward osmosis separation technology at home and abroad is also presented. Different materials and structures of forward osmosis membranes have been prepared successfully after years of hard work and research. The latest research progress of the membrane materials in FO field is presented. Application of many forward osmosis membrane materials is restrained by technical difficulties,which should be resolved in the future to shorten the gap between theory and practice,and achieve innovative results in the practical application of membrane materials.
