Abstract: 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.
