Shuiyi Slufri® SMU-F Series Equivalent to Suez Zeeweed 500D MBR Membrane
Seamless Equivalent to Suez Zeeweed 500D
Shuiyi Slufri® Series MBR Membrane Modules feature uniformly aligned fibers, peel-resistant coatings, stable water output in quality and quantity, extended cleaning intervals, and prolonged service life. Integrated with Shuiyi’s proprietary Pulse Aeration Technology, these membranes demonstrate strong market competitiveness across critical technical and economic indicators, including outlet water quality, operational cost, cleaning and maintenance requirement and service life. They are widely applicable in advanced sewage treatment, water reuse and diverse industrial wastewater recycling applications.
Description
- Automated Fiber Alignment — No Smudge Accumulation
Hot-melt adhesive fiber alignment ensures uniform spacing and orderly encapsulation of membrane fibers. It effectively enhances membrane module’s fouling resistance, reduces cleaning frequency and increases water production efficiency.
- High Physical Mechanical Strength — No Breakage or Delamination
Continuous optimization of membrane manufacturing technology strengthens the bonding between the filtration layer and the support layer, thus improves fiber tensile strength (＞140N) and peel strength (＞3N), enabling resistance to higher-intensity hydraulic shocks without breakage or delamination for long-term stable water quality.
- Small Pore Size, Uniformly distributed Pores — Stable and Reliable Outlet Water
With an average pore size of 0.03μm and uniformly distributed porosity, the membrane fibers effectively remove pollutants including suspended solids, bacteria, colloids and viruses, delivering stable and reliable water quality.
- High Porosity — High Flux
The high porosity of membrane fibers achieves a typical operational flux of 15-35 LMH of MBR membranes at normal temperature, reducing required membrane area and lowering system investment for greater economic efficiency.
- Fouling/Flux Decay Resistance — Extended Cleaning Intervals and Service Life
Shuiyi membranes employ proprietary hydrophilic modification technology, endowing hollow-fiber membranes with permanent hydrophilicity. This significantly enhances fouling resistance and flux decay resistance, extending cleaning intervals and service life.
