Pure water treatment process, there are the following methods:  

1, activated carbon adsorption process: activated carbon depends on adsorption and filtration effect of the main removal of heterochromatic water, odor, residual chlorine, residual disinfection and other organic impurities.  

2, membrane microporous filtration process: membrane microporous filtration method includes three forms: deep filtration, screen filtration, surface filtration.  

Deep filtration is an economical way to retain particles by means of adsorption or capture, and is usually used for pretreatment.  

Surface filtration is a multi-layer structure, when the solution passes through the filter membrane, the particles larger than the pore inside the filter membrane will be left behind, mainly accumulated on the surface of the filter membrane, can also be used for pretreatment or clarification.  

The screen is like a screen that leaves particles larger than the pore size on the surface and is generally placed at the final point of use in a purification system to remove trace amounts of resin flakes, carbon chips, colloid and microorganisms.  

3, ion exchange process: the principle of ion exchange method is the inorganic salt anion and anion in water, through the exchange of ion exchange resin, so that the Yin and cation in the water and the anion and anion in the resin exchange, so that the water is purified.  

4, EDI pure water treatment process: a new deionized water treatment method, also known as continuous electric desalting technology, EDI device will ion exchange resin filled in the negative/cation exchange membrane between the formation of EDI unit, do not need to use acid and alkali resin regeneration, good environmental protection.
