UF-160B UF(Ultrafiltration) Membranes(PVDF)

AquaDroplet Outside-In Ultra Filtration Membrane Elements

Polyvinylidene fluoride (PVDF) is used as the material, and its greatest characteristic is its high chemical stability. The chemical stability determines its outstanding antioxidant ability and acid and alkali resistance.

In order to ensure the normal operation of membrane components and stabilize water flux, it is necessary to clean the membrane regularly. The most effective method is oxidant cleaning. But oxidants can damage the membranes. The ability of polyvinylidene fluoride (PVDF) to withstand oxidants (sodium hypochlorite, etc.) is more than 10 times that of polyethersulfone, polysulfone, and other materials, thus greatly prolonging its service life. Polyvinylidene fluoride (PVDF) film also has strong flexibility. The results of the practical case investigation show that the PVDF film has the advantage of a minimum breakage rate. It has been more and more widely used in the field of sewage treatment. Sketch of characteristics of Runmo PVDF membrane module :

1. High antioxidant and cleaning resistance: High-quality polyvinylidene fluoride material determines the enhanced chemical stability of membrane products, and the high chemical stability of the membrane makes the membrane resistant to high concentration oxidant cleaning, thus effectively preventing microbial reproduction such as bacteria;

2. High Flux: High Porosity of Products, High Flux of Components;

3. High Strength: Good flexibility: Membrane wire has high strength and good flexibility. It is not easy to break during cleaning;

4. High pollution resistance: through hydrophilic modification, the product's pollution resistance is greatly improved;

5. Good Water quality : Ultrafiltration membrane has a small nominal aperture, so it can remove almost all suspended particles, microorganisms, colloids, pathogens and bacteria in the application of this product;

6. Long service life: Components usually adopt external pressure structure which is not easy to plug. They have larger filtering area and higher pollution interception, easy to clean, and more thorough. They can remove the fouling on the membrane surface in time, so that the service life of the membrane is longer.
