The process meaning sea water desaltination of fresh water is obtained from seawater.Method for desalting seawater now used have seawater freezing method,
electroosmose process, distillation method,
reverse osmosis method, apply at present
reverse osmosis membranereverse osmosis method simple with its equipment, be easy to safeguard and the advantage of EM equipment module dominates the market rapidly, progressively replace
distillationmethod becomes most widely used method.
There are 100 Duo Ge scientific research institutions of more than ten country in the world in the research carrying out sea water desaltination, have the sea water desaltination facility of hundreds of different structure and differing capacities in work.One modern large-scale
desalimtor, several thousand, several ten thousand even nearly 1,000,000 tons of fresh water can be produced every day.The cost of desalination water is constantly reducing, and some country has been reduced to the price difference of tap water few.The desalination water yield of certain areas reaches the water supply scale in country and city.
