Abstract: Basic principles of forward osmosis process are introduced. The characteristics of draw solution such as gaseous solution, inorganic salt solution, organic solution, magnetic nanoparticle solution, and hydrogels are summarized, and the relating research progress is also reviewed. Furthermore, the characteristics, existing problems and research status of several forward osmosis membranes, such as cellulose acetate membrane, polyamide thin-layer composite membrane, and aquaporin membrane, are systematically summarized. Research progress on the application of forward osmosis technologies in the fields of seawater desalination, sewage treatment, and industrial wastewater treatment is reviewed. Development prospect of forward osmosis water treatment technology is expected.
