  • 2.1 Desalination by reverse osmosis

    2.1 Desalination by reverse osmosis. Desalination is a separation process used to reduce the dissolved salt content of saline water to a usable level. All desalination processes involve three liquid streams: the saline feedwater (brackish water or seawater), low-salinity product water, and very saline concentrate (brine or reject water).
