  • 2.1 Desalination by reverse osmosis - OAS

    2005-6-6u2002·u20022.1 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).

  • Reverse Osmosis (RO) membrane desalination (desalting)

    2021-11-7u2002·u2002Introduction to Reverse Osmosis. Reverse osmosis (RO) is a membrane desalination technique employing a semipermeable membrane so tight that is able to hold back a number of monovalent ions. It is most commonly used in desalination due to the ability of the membrane to retain sodium and chloride ions (salt) while allowing water to pass.
