Product introduction:
Polyvinylidene fluoride (PVDF) hollow fiber prepared by phase inversion method ultrafiltration membrane It has excellent chemical stability and mechanical strength, with a molecular weight of 00015.00000Da. It has good retention effect on macromolecular substances (proteins, various types, nucleic acids, polysaccharide particles (latex, microparticles), bacteria, etc. In view of the problem that PVDF membrane has strong water property and is easy to be polluted, the amphiphilic polymer modifier of our company's main intellectual property right is used for hydrophilic modification to prepare the hydrophilic PVDF hollow fiber ultrafiltration desert with high flux and anti pollution.
Product features:
1. High water flux and good permeability
2. Higher suspended solids content and larger particle diameter of influent are allowed
3. High filtering precision and excellent interception performance
4. Hydrophilic modification of independent intellectual property with strong hydrophilicity
5. Excellent anti pollution performance
6. High mechanical strength, the tensile force of a single homogeneous membrane can reach 280~300g
Main applications:
1. RO pretreatment and post-treatment
2. Impurity removal, bacteria filtration and concentration in food, pharmaceutical and fermentation industries
3. Reclaimed water reuse
4. Drinking water supply treatment

Note: The above data are for reference only, and the test conditions are: 25 ℃, 0.1Mpa. The cleaning shall be carried out before the ultrafiltration membrane causes serious pollution, so that the membrane flux can be easily restored to the initial state. The cleaning interval is generally based on the on-site raw water test.
