Water resources in our world are immense since 97% of the earth’s surface is Sea water. Unfortunately less than 1% of the available water resources are potable or sweet water fit for human consumption. Sadly, Over 30% of the worlds countries with substantial population are water deficit countries. The WHO ( World Health Organization) has stipulated a Minimum of 50 liters per head as the minimum requirement of sweet /fresh water for an individual to maintain a level of Hygiene but except some developed countries most face perineal shortages as a result the residents of these underdeveloped and developing countries are able to source only a fraction of the WHO recommendation for clean water for their personal use Removal of salt from sea water has been known for many centuries as a concept and practice but only recently have various processes been developed by Researchers, Scientists and Engineers to commercially process sea water to yield sweet water or potable water. The article below describes briefly the several available processes and technologies to process sea water to yield sweet water in commercial quantities and at the most economical operating conditions.
