How does Ultrafiltration Water Treatment System work?

Ultrafiltration, also known as UF system, is used to retain colloid-sized particles in water while allowing water and low molecular weight solutes to pass through a membrane. The mechanism of ultrafiltration refers to the comprehensive effect of mechanical sieving on the membrane surface, membrane pore blocking and adsorption on the membrane surface and membrane pores, mainly sieving.
Ultrafiltration is one of membrane separation techniques driven by pressure. For the purpose of separating large and small molecules, the pore size of the membrane is between 20-1000A°. Hollow fiber ultrafilter (membrane) has the advantages of high filling density per unit container and small footprint.

Ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, the small molecules of solute and solvent through a specific aperture of the membrane, while the large molecules of solute can not penetrate, left on one side of the membrane, so that the macromolecular material has been partially purified. Ultrafiltration is one of membrane separation techniques driven by pressure. For the purpose of separating large and small molecules.

Ultrafiltration Water Treatment System steps:
1. Sand filter: use 0.5-1 mm sand medium. The filter can be as small as 200 microns in size. Some large suspended solids such as suspended solids, rust, mud, impurities, etc. can be trapped by the medium bed. And removed from the water. steps
2, activated carbon filter: can absorb some organic matter, dissolved air, smell and color substances. steps
3, softener (optional): the use of cation exchange resin to remove calcium, magnesium and other soft water.
4, micron filter: use 5-20 micron precipitate cartridge filter/bag filter, remove the suspended solid through the pretreatment. So the RO entrance is more secure.
5. Ultrafiltration system (ultrafiltration membrane intercepts most ions. Demineralization/desalination, etc. The output will be pure water.
6, ultraviolet sterilizer (ozone generator): used to kill bacteria in water, safe to drink.
