Saudi Arabia now more than 3.3 million liters per desalination, accounting for 18% of world desalination production. jordan shoes shop,Additional as we have learned, Saudi Arabia in recent years will cost 40 billion LiYaEr ($10.7 billion) in the new series of water supply projects, including seawater desalination and water projects.

16 th century, Britain's queen Elizabeth had issued a command: who can invent a cheap method, the bitter xing salty seawater desalination into available for human consumption of fresh water, who can get a prize of $10000. 16 th century, human try distiller in the ship direct evaporation sea water to making fresh water, created the artificial desalination precedent. Supra Skytops,The 19 th century, due to the common development of steam, evaporator has flourished, to meet the boiler water and part of the drinking water needs. In 1877, Russia in Baku built world's first fixed freshwater device. Other countries, especially the lack of rain drought countries also set up one fixed freshwater device. However, the real large-scale desalination, is in the late 1950 s. According to statistics, at present on the world 70 DuoGe countries engaged in seawater desalination work. Only in June 1980, distillation, the method and electrodialysis method three types of desalination devices is the world of 2204, a total of about 7.27 million tons of water made every day. Kuwait's "multi-stage flash urgent distillation" device of 32 level, its seawater desalination level is the highest in the world first-class. In today's world freshwater 70% of production is to use this method of production, to nissan 180000 tons of water.air jordan shoes, China seawater desalination technology research started in 1958, and in recent years the seawater desalination technology the emergence of a new progress: salinity bitter salty seawater desalination in components and frequent fall extremely significant achievements into electrodialysis technology international advanced ranks. Saudi Arabia is the world's largest desalination producers, the sea water desalination is of the world total of about 21%.

Also can use crystallization method desalination. To join in the ocean in the extremely easily, butane butane volatile, when sea water in the quantity of heat of volatile away, the sea ice, so that the salt and water separation.
