External Pressure Reinforced Hollow Fiber Membrane PVDF Material Shuiyi Slufri® SMU-M
Shuiyi Slufri® Series MBR Membrane Products utilize low-pressure high-flux PVDF hollow fiber composite membranes with evenly spaced fiber technology. The membrane cassette is equipped with a pulse aeration device, featuring high operational flux, stable water quality, strong anti-fouling capability, long service life, and low energy consumption. Additionally, compared to traditional MBR membranes, the air-to-water ratio can be as low as 5:1, reducing energy consumption by more than 40%, making it widely applicable in municipal and industrial wastewater treatment sectors.
Description
- Small pore size, large flux
The membrane fibers have an average pore size of 0.05μm, with uniform pore distribution, high porosity, higher anti-fouling properties, and longer service life. By adjusting the membrane material formula and upgrading the process, the operational flux has increased by 25%. - Long service life
The membrane fibers have a tensile strength >150N and peel strength >3N, can withstand higher intensity backwashing without breaking or peeling, and have a long service life. - Anti-fouling, not trap mud
The series uses automated spacing of hot melt adhesive, ensuring evenly spaced and neatly arranged membrane fibers, effectively enhancing the anti-fouling properties of the membrane elements, preventing mud trapping, reducing cleaning frequency, and increasing water production efficiency. - Low operational energy consumption
Shuiyi ESP high-efficiency energy-saving membrane assemblies use large bubble pulse aeration technology, reducing aeration by 40% compared to traditional continuous aeration, lowering the air-to-water ratio to below 5:1, and significantly reducing energy consumption. - Operable without backwashing
With the new product upgrade, it can operate without backwashing, effectively improving water production efficiency and quantity, achieving energy savings and consumption reduction.

Note:
(1) Pore size is tested according to GB/T38949-2020 Determination of Pore Size for Porous Membranes Standard Particle Method;
(2) Operational and backwash fluxes depend on the overall system operation and maintenance;
(3) Aeration intensity is calculated based on the upward-facing projected area of the membrane modules;
(4) During cleaning under standard conditions at 30°C;
(5) Produced water quality metrics may slightly vary depending on the inlet water quality.
The data presented herein have been tested and are reliable, but variability may occur due to different testing methods and operating conditions.
