Forward osmosis（FO）is a low energy consuming and efficient solution for water and environmental problems. FO converts osmotic energy to electricity via pressure retarded osmosis process,therefore it is also a green energy technology. In recent years,FO has attracted worldwide attention for research and development,ranging from governmental funding to company research plan. In this review,the state-of-the-art in FO membrane materials and applications are summarized. Various applications of FO in seawater desalination,osmotic power,wastewater reuse,aeronautics and astronautics,beverage and other novel processes are introduced.
