Product Description

The principle of the sea water desalination there are a lot of salt. 

From the vast ocean can get rid of salt, extract the fresh water? Seawater desalination is human pursue hundreds of dream. As early as in the world of great maritime era, British royal family is offered for cost-effective seawater desalination method. Today, the seawater desalination method although had hundreds of species, production of fresh water also flavor varies, but to cost-effective measures, still not satisfactory.

 See the surface water desalination is very simple, as long as the salt and fresh water separate salt water can. The simplest method, one is the distillation, will evaporate and salt water left, then water vapor condensation for liquid water. This process and water gradually become the salty process is similar, only humans to grab is fresh water.

     Another seawater desalination method is freezing method, frozen sea water, ice, in the solid ice into liquid water at the same time, salt was separated out. The two methods are difficult to overcome shortcomings. Distillation will consume large amounts of energy, and in the instrument in a significant amount of pot scale, instead get the freshwater is not much. This is a kind of very not cost-effective way. Freezing method also consume much energy, get the freshwater but taste not beautiful, difficult to use.

In 1953, a new kind of seawater desalination way has come out, this is the method. This method using a semipermeable membrane to achieve will be fresh and salt the purpose of separation. Normally, a semipermeable membrane allow solution of solvents, through, and not allow solute through. Due to the high sea salt, if use a semipermeable membrane sea and fresh water will be separated, the freshwater fusion half semipermeable film spread to one side of the sea, which brought the sea side of the liquid surface increases, until a high stress, make fresh water no longer spread to come over. 

This process is penetration. If do exactly the opposite, and to be fresh water, as long as the of the sea water with semipermeable film pressure, can make the seawater in the fresh water permeate a semipermeable membrane outside, and salt was film block in sea water. This is the method. The biggest advantage of the method is energy saving, the production of the same quality fresh water, its energy consumption is only 1/40 of the distillation.

Therefore, since 1974, the developed countries of the world to coincide the ground seawater desalination research direction to the method.
