  • 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).

  • Green Reverse Osmosis Pretreatment for Shipboard

    2010-4-27u2002·u2002US Navy ships currently employ reverse osmosis (RO) as the method of desalinating water for use as potable water on sea vessels. RO desalination is very effective; however, it is subject to scaling and fouling, which reduces the lifespan of the membrane and increases cost. The current pretreatment system for the RO is cartridge filtration.
