Ultrafiltration Method
- Jun 15, 2018 -

Ultrafiltration principle: ultrafiltration is a pressurized membrane separation technology, namely under certain pressure, make a small molecule solute and solvent through a certain aperture of a special film, and make the macromolecular solute can't through, stay in the film, which results the macromolecular material part of the purification. Ultrafiltration is also a membrane separation process. The ultrafiltration micropore is less than 0.01 micron, which can completely filter bacteria, rust, colloids and other harmful substances in water, and retain the original trace elements and minerals in water.



Ultrafiltration membrane: it is a kind of microfiltration membrane with uniform pore size and rated pore size ranging from 0.001 to 0.02 microns. Ultrafiltration membrane can be divided into inorganic membrane and organic membrane according to different membrane materials. Inorganic membrane is mainly ceramic membrane and metal membrane. The organic film is mainly made of high molecular materials, such as polyvinylidene fluoride (PVDF), polysulfone ether (PES), polypropylene (PP), polyethylene (PE), polyacrylonitrile (PAN), polyvinyl chloride (PVC), etc. For example, the vertical water purifier USES PVC alloy film, which has the advantages of good hydrophilicity, high punching precision and corrosion resistance.



Ultrafiltration water purifiers, water ultrafiltration water purifier system can completely get rid of the bacteria in the water, rust, colloid and other harmful substances, and can retain the original trace elements and minerals, water supplement our daily needs. Such water is safer than white water and healthier than pure water. To some extent, it can truly meet our daily drinking water and water needs.
