PVDF Material Ultrafil™ NIPS Series Pressurized UF Membrane (UP) Products
Shuiyi Ultrafil™ NIPS series pressurized UF membrane products are made from high-standard PVDF using a wet phase inversion process to form homogeneous hollow fiber membranes, offering exceptionally high removal rates for suspended solids, colloids, microbes, bacteria, and viruses, ensuring consistent and stable water quality. The standardized membrane modules feature an outside-in configuration for enhanced tolerance to variable feed water quality. With a comprehensive product range and dimensions compatible with mainstream market offerings, they enable seamless replacement.
The modular skid design enables flexible scalability and seamless system integration, featuring simplified installation procedures and minimized maintenance costs.
Description
- High flux with anti-fouling performance
Utilizing patented hydrophilic modification technology, it offers excellent anti-fouling performance, maintaining high operational flux at low transmembrane pressure, and features a longer membrane flux decline cycle during application. - Superior water quality
With a 0.03μm high-precision filtration pore size and a 3D interconnected sponge-like pore structure, it achieves high removal rates of colloidal particles, bacteria, and viruses, ensuring consistently excellent produced water quality. - Long service life
Membrane fiber sealing uses a centrifugal potting process, creating a bubble-free sealing layer and no glue creeping at the root, capable of withstanding repeated high-intensity air-water scouring, minimizing the risk of fiber breakage and extending lifespan. - High water production efficiency
Membrane fibers are made from high-standard PVDF, offering excellent mechanical properties, with a breaking force ≥4.5N, and elongation ≥150%. The application process allows for combined air-water backwash, enabling thorough cleaning and effective pollution control while reducing backwash water use, increasing water production efficiency, and achieving a recovery rate of over 95%. - Universal design for worry-free replacement
Shuiyi pressurized UF membrane products can seamlessly replace mainstream UF membrane products on the market, with simple installation, low retrofitting costs, and convenient, worry-free operation and maintenance.

Note:
(1) Test method: Determination of Pore Size for Porous Membranes — Standard Particle Method GB/T38949-2020;
(2) The influent condition parameters are values under extreme laboratory testing conditions;
(3) Operational and backwash flux depend on the operation and maintenance of the entire system;
(4) Produced water quality metrics may vary slightly depending on the quality of the influent. The data presented herein have been tested and are reliable, but variability may occur due to different testing methods and operating conditions.
The data presented herein are derived from specific tests and are true and reliable. However, differences may exist between test conditions and actual application environments, so actual results may vary. It is recommended that users verify and adjust according to their specific operating conditions and assume relevant responsibilities themselves.
