QJ submersible pump used for seawater desalination
2012 February the Circular of the general office of the State Council on to accelerate the development of seawater desalination industry opinions "(hereinafter referred to as the" opinions ") clearly pointed out that seawater desalination is in China to ease the situation of shortage of water resources is one of the most important measures, is an important part of strategic emerging industries, but also the development of the ocean economy an important part. According to its development goals, in 2015 China's desalination capacity will reach 2 million 600 thousand to 2 million 200 thousand cubic meters / day, an increase of 4 times compared to the end of 2011.
This goal may be just the beginning. The global water shortage has decided the sea water desalination industry has the huge market prospect and the good industrial development environment. If according to the seawater desalination equipment per ton per day of 7000 yuan investment cost estimates, light seawater desalination equipment the, to 2015 the seawater desalination project or driven investment more than 100 billion yuan, global market of up to 100 billion level.
Comprehensive utilization of concentrated sea water is also worth looking forward to. It is understood that after desalination of seawater produced by the ultra concentrated sea water, salt close to 40%. "We will extract potassium from it." Xu Zhongming revealed that the current design of the brine system has been approved by the plant, next year will rely on the existing desalination project in Yueqing power plant construction of the first potassium plant. According to the sea water desalination capacity of tons per day, can be extracted from potassium chloride (KCL) about 17 tons, a year down can be made of Potash (including KCL95%) about 6000 tons.
