Shuiyi Slufri® SMR Series MBR Membrane
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 water quality, strong fouling resistance, extended lifespan, and low energy consumption.
Compared to traditional 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.
- Uniform pore size, increasing flux
The membranefibers have anaverage pore size of 0.03 μm,with uniform pore distribution and high porosity, offering strong anti-fouling performance and anoperating 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. - Packaged, Anti-Fouling and Enhanced Efficiency
Utilizing automated hot-melt adhesive membrane sheet arrange ment 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 and peel strength >3N, can withstand higher intensity backwashing without breaking or peeling, Extended service life to 5-10 years.
