What is the role of ultrafiltration membrane?

Different from activated carbon, KDF adsorption, ultrafiltration membrane and PP cotton and so on belong to the intercepting membrane, through the very small pore size, the bacteria and magazines will be intercepted on the outside, leaving clean water, the difference lies in the filtration accuracy and cleaning methods.

Ultra-filtration membrane is one of the early development of polymer membrane, its membrane pore size range of about 0.01-0.1 um. The use of purely physical filtration, that is, in the solution through the semi-permeable membrane, under the action of the pressure, the solvent and solute in the small molecules of the material can be filtered through the membrane to reach the other side of the membrane, and solute in the large molecules of material and colloid due to the inability to pass through the filter membrane holes and be intercepted. As the solution continues to flow through, the membrane is intercepted more and more substances, so in order to realize the role of ultrafiltration, it is necessary to exert greater pressure on the solvent, and at the same time in the formation of the surface of the membrane of the material shows certain chemical properties, for some pollutants have the role of retention and decomposition, so as to realize the purification of water.

In many central water purifiers, LISI uses PVC alloy capillary ultrafiltration membrane, its filtration aperture reaches 0.01 microns, it is not exaggerated, which is one ten thousandth of a hair, can effectively separate the large particles in the tap water impurities and harmful impurities, while retaining the original water beneficial to the human body of natural minerals and trace elements. Can also be in the daily wash rags, do hygiene by hand when opening the valve on the cartridge rinse, not only waste of water, but also rinse out the dirt that is retained in the ultrafiltration membrane, both to extend the service life of the cartridge, but also to reduce the frequency of core replacement. And its one in two out of the product structure design, so that the water and straight through the water have their own separate channel, to avoid the purified water is the second pollution. In this way, the cartridge is not dirty and blocked, the water output is large, but also to always ensure that the family water clean, pregnant women, infants, the elderly have the benefit of really suitable for people to drink for a long time.
