Research Progress in Treatment of Wastewater Using Forward Osmosis Mixed Inorganic Salts as Extraction Solution
In recent years,forward osmosis technology with the advantages of low energy consumption,low pollution,and recyclability,has been widely applied in sewage treatment and other fields.How to choose an efficient and stable extraction solution is the core problem that forward osmosis technology needs to solve.In this article,the application of forward osmosis technology in wastewater treatment in the past 10 years was reviewed,the evaluation indicators and influencing factors of different extraction liquids for forward osmosis were discussed.The scale of mixed inorganic salts as extraction liquid in the future was prospected to promote the application of forward osmosis process with mixed inorganic salts as extraction liquid in sewage treatment field.
