- PVDF Material, chemical cleaning resistance, excellent oxidation resistance
- High filtration precision, nominal pore size 0.03 μm, uniform pore size distribution
- High strength and good toughness (the elongation of the membrane exceeds 100%)
- Low pressure and high flux (design flow can be met under very low trans-membrane pressure difference)
- Good chemical stability (the performance of the membrane module remains unchanged after 50 times of acid and alkali chemical cleaning)
- Strong anti-pollution ability (the cleaning cycle is extended by 30%, and the membrane flux recovery effect is good)
- External pressure type use, strong dirt holding capacity and wider water quality
- Standard accessory connection method greatly improves the convenience of component installation

Working Process
In the process of UF membrane filtration, the pressure difference on both sides of the membrane is used as a driving force and UF membrane as the filter media.
Outside-In UF Membrane
Feed water enters the center tube of the UF membrane module from one end and flows through the surface of the hollow fiber membrane. Under the action of pressure difference, water and small molecules flow to the inside of the UF membrane through the dense micro pores and become the permeate, and then flows out from the other end of the UF membrane. The substances larger than the micro-pores in the feed water are retained on the surface of the membrane and become concentrate, and then flows out from the side port.
