PVC UF Membrane price


Similar to reverse osmosis, ultrafiltration (UF) is a membrane filtration method that pushes water through a semi-permeable membrane using hydrostatic pressure. To create water with extremely high purity and low silt density, UF uses pressure as a pressure-driven barrier to suspended particles, bacteria, viruses, endotoxins, and other pathogens.

The bilateral cortex structure of asymmetry is applied in the modified PVC membrane hollow fiber. The liquid is filtrated twice during operation, thus the quality of product water is assured.

The material used to create PVC UF Membranes is modified PVC hollow fiber UF membrane, which has the advantages of high strength, big flux, acid and alkali resistance, and resistance to washing.

The final filtering step or cross-flow filtration can both use hollow fiber PVC UF membranes. To guarantee the membrane system operates steadily and consistently over the long term, contaminants can be eliminated through routine physical and chemical cleaning. In industrial filtration and reverse osmosis prefiltration systems, PVC UF membranes are frequently employed.

Brother Filtration PVC UF membrane hollow fiber made of imported raw material has excellent mechanical performance which prevents the breakage of hollow fiber effectively. Its outstanding performance of antipollution allows a very low operation pressure avoiding the form of concentration polarization on membrane hollow fiber surface.

The structuring of micropores filtrate passage utilizes internationally advanced pore-forming technology, with trumpet-shaped filtrate passages radiating from inside to outside. Thus the membrane flux rate would be recovered to a maximum extent.

Excellent chemical stability is a guarantee to clean pollutants such as microbes, and organic and non-organic substances off the membrane cortex surface efficiently in chemical washing, hence recovering flux rate and extending the life span of the membrane.

Brother Filtration PVC UF membrane is suitable for applications such as desalination of sea or brackish waters, prefiltration for RO system, reuse or conditioning of industrial water, municipal/tap water purification and municipal & industrial wastewater recycling.


Brother Filtration always use high quality raw materials to produce high-quality products. The PVC UF membrane is made of imported raw materials, which enables it to be more strong, more competitive, and more durable.
