Abstract: With the sustainable development of society, the water resource was seriously polluted and the phenomenon of water resources shortage was occurred, which not only limited the development of society, but also endangered the survival of mankind.In order to relieve the strain on water resources situation, the processing of brackish water recycling has become the best way to solve the water problem.In this paper, the research progress of reverse osmosis technology desalination and new energy recycling technology in brackish water area were introduced, the properties and characteristics were analyzed and the shortages were pointed in application process.Finally, the future application trends were discussed.

Key words: brackish water;reverse osmosismembrance;desalination technology
