Slufri® SMR Series MBR Membrane Products
Shuiyi Slufri® SMR MBR membrane series utilizes a low-pressure, high-flux PVDF hollow-fiber composite membrane with hot-melt adhesive automated sheet placement. The membrane module integrates a pulse aeration system, delivering advantages such as high operational flux, stable permeate quality, strong fouling resistance, extended lifespan, and low energy consumption.
Compared to conventional MBR membranes, it achieves an air-to-water ratio as low as 3:1,reducing energy consumption by over 40%. The product is widely applicable in advanced wastewater treatment, reclaimed water reuse, and the treatment and reuse of various types of industrial wastewater.
Description
- Smaller pore size, increasing flux
The membrane fibers have an average pore size of 0.03 um, offering higher filtration precision and excellent integrity, with produced water quality meeting reverse osmosis feed water requirements. They also provide strong anti-fouling performance, with operating flux 40% higher than industry-leading products.
- Pulse aeration: energy saving and cost reduction
Equipped with Shuiyi ’s ESP high-efficiency, energy-saving large-bubble pulse aeration technology, it reduces aeration volume by 40% compared to industry standards, achieving an air-to-water ratio below 3:1. Cleaning cycles are extended to 1.5-2 years, significantly lowering energy consumption and operational costs.
- Neatly packaged, anti-fouling and enhanced efficiency
Utilizing automated hot-melt adhesive membrane sheet arrangement technology, membrane fibers are uniformly spaced and neatly arranged. This prevents sludge accumulation, reduces cleaning frequency, and improves water production efficiency.
- Backwash-free design, enhanced performance
Backwash-free operation is supported to boost water production efficiency and output while reducing energy consumption.
- High-strength material, durable and long-lasting
The membrane fibers have a tensile strength >110N (up to over 600N depending on application) and a peel strength >3N, making them not easy to break or peel. Combined with excellent anti-fouling properties, their service life is extended to 5‒10 years.

Note:
(1) Pore size is tested according to GB/T38929-2020 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 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.
