External Pressure Reinforced Hollow Fiber Membrane PVDF Material Shuiyi Ultrafil™ UP Series
Shuiyi Ultrafil™ series pressure UF membrane products are made from high-standard PVDF to form homogenous hollow fiber membranes, offering exceptionally high removal rates for suspended solids, colloids, microbes, bacteria, and viruses, ensuring consistent and stable water quality. Standardized membrane modules with an external pressure structure can accommodate a wider range of inlet water qualities; the module categories are complete and compatible with mainstream market products, allowing for seamless replacement. Modular rack design facilitates expansion and integration, with easy installation and low maintenance costs.
Description
- High anti-fouling flux
Utilizing patented hydrophilic modification technology, it exhibits excellent anti-fouling capabilities, maintaining high operational flux at lower transmembrane pressure differentials, and features longer periods before flux decline during application. - Exceptional water quality
0.03μm high-precision filtration pore size with a homogeneous sponge structure, achieves high removal rates of colloidal particles, bacteria, and viruses in the water, ensuring the produced water quality is consistently excellent. - Long service life
Membrane fiber sealing uses a centrifugal sealing process, creating a bubble-free sealing layer and root without creepage, capable of withstanding repeated high-intensity gas-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 gas-water backwashing, 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 structure, worry-free replacement
Shuiyi pressure 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.
Therefore, users should combine practical application processes and thoroughly understand the products of Ningbo Shuiyi Membrane Technology Development Co., Ltd.
