Abstract: |
|
China is one of the countries with the poorest water resources per capita in the world. Desalination of seawater and brackish water is an important method to solve the shortage of water resources in China. Membrane desalination technologies such as reverse osmosis (RO) and nanofiltration (NF) have the advantages of low investment, low energy consumption and easy to realize automatic control, which are currently widely used and have become an important development direction for desalination. Pervaporation (PV) is an early membrane separation technology which is widely used in the separation of organic matter and water. Compared with the other membrane technologies, pervaporation desalination has the advantages of high salt rejection rate, low energy consumption and low pretreatment requirements, and so its research and application in desalination have drawn more and more attentions in recent years. In this paper, the principles, the mass transfer models, the influencing factors of desalination process, and the membrane types for pervaporation desalination are summarized and reviewed to provide reference for the research and application of pervaporation desalination technology. |
