  • Desalination - USGS

    2019-6-6 · Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants.

  • From Sea Water to Drinking Water: Resolving World's

    2020-8-5 · Seawater accounts for over 97% of the Earth's water. One desalination technology, the RO (reverse osmosis) membrane method, utilizes the principle of osmotic pressure. Membranes with countless fine pores only allow water molecules to pass through, allowing impurities like salt to be filtered from seawater (Fig. 2).
