   ultrafiltration water purification machines principle of what is it? The problem is simple, but many people could not answer.




Development of a water purifier gone through many stages, of which there is a physical method, chemical method. But the development to the present day, household water purification equipment, basically using the same kind of works: membrane filtration technology. This technique is extremely micron pore size membrane filter to the pore size greater than this filter out impurities, to achieve water purification, household water purification techniques is the cost and best effect. Xiao Bian gave you tell us about the ultrafiltration water purification machines principle.


us to understand under the ultrafiltration membrane made of raw materials, it is mainly chemical compounds. With a PVC film, PAN film, PVDF film a variety of conventional ultrafiltration membranes. PVC film is the familiar plastic film, and this film is currently in the domestic water purifier used widely, is a more mature technology. It quality stability, good flexibility, easy broken wires; high filtration precision, low moisture absorption, rinse; resistant to acid, alkali resistance, and long life. Expo drinking water use is this food-grade PVC alloy membrane. Other films such as PAN, PVDF film due to non-food grade material, with less.


The minimum pore size of the ultrafiltration membrane up to 1 nm (i.e. 0.001 microns, then if the pore size is small, less than 1 nm, that is, the reverse osmosis membrane, that is used to manufacture the pure water, i.e., in addition to water molecules, further does not contain any other substance), almost all bacteria are larger than 100 nanometers (0.1 microns), an ultrafiltration membrane can thus filter out bacteria, and not leave their bodies, and calcium, magnesium, potassium and other minerals beneficial to the diameter less than 10 nanometers, and just through an ultrafiltration membrane. This water contains minerals beneficial to the human body the right amount, beneficial to human health, so now both at home and abroad, almost all manufacturers are using an ultrafiltration membrane water purification to the production of household water purifiers.


This is the working principle of the membrane, was filtered off through water purely physical rust, silt, organic molecules (water, chlorine, etc.) and the like bacteria and viruses, minerals and trace elements in water retention.


These are the water purifier knowledge introduction, after reading, you should know it. In fact, under normal circumstances, the water is still relatively clean and healthy, so do not be necessary to install a home water purifier it issuesTangle. It is important to have some more knowledge of small household drinking water, will not live without water trapped.
