Stainless Steel Seawater Desalination Device (seawater)

In the total reserves of global water, sea water accounts for 96.5%, convert the sea to fresh water is the ultimate way of solving water shortage. Seawater desalination is a technology and process by removing most of the salt from seawater to get fresh water. Currently the method of desalination mainly include distillation and membrane separation.

Distillation include Low-temperature multi-effect distillation (LT-MED), multi-stage flash (MSF), steam pressure distillation (TVC and MVC) technology; Membrane separation include sea water electrodialysis desalination (SWED) and sea water reverse osmosis (SWRO) technology, mainly in SWRO.

Membrane separation and distillation seawater desalination is suitable for different occasions, different dimensions, different users, the characteristics of two kinds of methods are as follows:

1)Membrane separation desalination compare with distillation desalination. There are some differences on the purity of product water, according to the different water quality requirements, can appropriate desalination method.

2)Membrane separation desalination mainly consume electricity. Distillation desalination mainly consume heat energy. From the standpoint of comprehensive utilization of energy, distillation available power plant waste heat energy, is suitable for cogeneration.

3)Membrane separation desalination device's localization scope is larger than distillation desalination, less equipment investment, low energy consumption, short construction period...

4)Membrane separation desalination is fit for large, medium and small scale desalination factory; But distillation desalination is only suitable for the large water desalination system

5)Membrane separation desalination device's investment is less than distillation desalination

6)Membrane separation desalination device's cost of making fresh water is lower than distillation desalination's.

Product applications:

The development and application of desalination technology in China since the 1970s. At first, it's a generalization of the sea water electrodialysis desalination device. Our country has built the first set of electrodialysis sea water desalination device in xisha islands in 1981, since 1990, we have successively completed many sets of seawater reverse osmosis equipment. At present our country has built the largest membrane separation desalination system, which is 10 tons of seawater desalination system in Tianjin Xinquan water desalination company, invested by Singapore Hyflux Group. At the same time, our country has been exported many set of seawater desalination equipment to the Maldives and Kiribati developing countries.

Our company membrane separation desalination engineering applied in Pakistan's gwadar port project. In t
He paracel islands, dalian ChangHaiXian island, which has built many sets of membrane separation desalination system, Besides, we also have been successfully exported many sets of sea water desalination equipment to the Maldives and Kiribati developing countries.
