Product introduction：
Prepared by Phase Inversion Method, PVDF Hollow Fiber UFMembrane has excellent thermal, chemical stability and mechanical strength. The molecular weight cut-off(MWCO)isaround 10kdal to 150kdal. PVDF membrane can efficientlyintercept Macromolecules(Various Albumin, Enzymes, Nucleic Acid and Polysaccharide, etc. ) Colloids (Latex and Microparticles)and Bacteria. As for PVDF membrane s stronghydrophobicity and high risk of being contaminated, JEFFELadopted Amphiphilic Polymer Modifier, a proprietary intellectual property right, to do hydrophilization on membrane,thus manufactured high-flux, anti-pollution HydrophilizedPVDF Hollow Fiber UF Membrane
Product features：
1. high water flux and good permeability.
2.Allow for higher content of suspendedsubstances and longer particle diametersin feed water
3.High filtering precision and excellentinterception performance
4.Hydrophilic modification with a proprietaryintellectual property right, and strong hydrophilic
5.Excellent Anti-pollution Performance
6.High mechanical strength (The tensile strengthof single fiber can reach up to 280-300g)
Main applications:
1.Pretreatment and Post-treatment for Reverse Osmosis(RO);
2.purity filtration, Sterilization, and Concentration, etc in Food, Pharmaceutics, and Fermentation industries;
3.Reuse of Intermediate Water
4.Water Supply Treatment for Drinking Water

Note: the above data are for reference only. The test conditions are: 25 C, 0.1Mpa. Cleaning should be done before the ultrafiltration membrane does not cause serious pollution, so it is easy to make the membrane flux restore to the initial state, the cleaning interval is generally based on the field test of raw water.
Zhejiang jeffel Environmental Science and Technology Co., Ltd.was specializes in the R&D, industry manufacture, engineering application and market promotion of the materials and products used for filtration, separation and purification.
