Pore size and filter object of micro-porous membrane filter
Micro-filtration is a kind of precision filtration technology, its aperture is generally 0.1μm-10μm, which is between general filtration and ultra-filtration. The use of microfiltration is very extensive, from production to life, from gas to liquid, from filtering impurities to sterilization filtration.
The micro-porous membrane filter used in microfiltration is generally called: Filter element; water filter element; micro-porous filter element; micro-porous membrane filter element; folding/pleated filter element; micro-porous membrane filter.

According to the material, it can be divided into: PES Membrane (PES) folding-pleated filter cartridge; polytetrafluoroethylene filter cartridge; Nylon Membrane (N6/N66) folding-pleated filter cartridge; polyvinylidene fluoride membrane (PVDF) folding -pleated filter cartridge; mixed cellulose membrane (MCE) folding -pleated filter cartridge; polypropylene (PP) folding -pleated filter cartridge; Glass Fiber (GF) folding -pleated filter cartridge and so on.

According to the application and function called: liquid filter; gas filter; removal of impurities filter; removal of bacteria filter; liquid sterilization filter; gas sterilization filter, etc. .
Aperture size and filter object

Filter classification	MEMBRANE PORE SIZE	Filter Object
Coarse filtration	40-1000μm	visible suspended matter, sand, impurities, etc
General filtration	10-40μm	invisible suspended matter, particles, impurities, etc
Microfiltration	0.1-10μm	bacteria, particles, impurities, etc
ULTRAFILTRATION	0.001-0.1μm	PROTEIN and other macromolecular material cut molecular weight (10,000-tens of thousands)
Reverse Osmosis	< 0.001μm	molecular weight of metal ions and non-polar Salts (30-10,000)
Nano filtration	1-30nm	cut molecular weight of polysaccharide, Amino acid, etc. (200-20000)
