Abstract: Forward osmosis(FO)has recently been an emerging water treatment technology,whose research and development have pointed at the treatment reuse of various refractory wastewater and material separation fields since its beginning,having wide development space. At present,its research is putting its focus on the selection of membrane materials and draw solution. Based on FO principles,the frontier science and technology achievements of FO membrane materials and draw solution are introduced,and the future choice directions of them are analyzed. At the end,the superiorities of FO technology are summarized,and the future application of FO is looked ahead.

Key words: osmosis, forward osmosis, draw solution, membrane material, reuse water, desalination process
