one such solution is desalination, the process by which salt water is converted into drinkable fresh water. This involves the removal of salt compounds and other chemicals from the salt water. a process which has traditionally been carried out by heating the water (the thermal method). the main disadvantage of this method has been developed, whereby salt water is purified by passing it though membranes. this method is used most effectively in combination with the thermal method.
Since 1958,china, one of the driest countries in the world,has used these two method to exploit its 32000-kilometre coastline and convert sea water into fresh water. to maximize efficiency, the Chinese have successfully combined a desalination plant with a power station in Zhejiang Province, using water from the Pacific Ocean to produce fresh water to generate electricity.
