MBR Membrane

Overview of MBR Membrane Technology

MBR membrane , as a type of microfiltration membrane, can effectively remove pollutants such as suspended solids and microorganisms from wastewater, producing high-quality purified water. It is widely used in wastewater treatment, industrial wastewater treatment, and water resource recovery, offering excellent water purification performance and space-saving advantages.

Our MBR membranes are made of hollow fiber PVDF membrane with high tensile strength and excellent chemical corrosion resistance. The 0.1 μm pore size provides excellent rejection of suspended solids, bacteria, and viruses. Compared with conventional treatment, SWB MBR modules produce extremely high quality permeate. Due to the high mixed liquor suspended solids (MLSS), SWB MBR modules can greatly reduce the overall treatment plant footprint and annual operation cost.

SWBT PTFE-MBR modules are made of highly hydrophilic PTFE membrane fiber, which have excellent chemical resistance and high hydrophilicity. With 0.1 μm filtration pore size, it has excellent retention effects on impurities such as solid particles, colloidal suspensions, and bacteria. Compared to traditional treatment processes and PVDF MBR membrane products, SWBT PTFE-MBR modules have the advantages of small footprint, better effluent quality, longer service life, and stronger chemical cleaning tolerance.

Working Principle

The MBR membrane system consists of two stages: biological reaction and membrane separation. When the wastewater enters the bioreactor, microorganisms convert pollutants such as organic matter, nitrogen, and phosphorus into microorganisms and gas through metabolic activities.

The wastewater treated in the bioreactor enters the membrane separation stage. The small pore size of the MBR membrane retains pollutants such as suspended solids, microorganisms, and solid particles on the membrane surface, forming concentrated sludge. Clean water molecules pass through the membrane pores and flow out of the MBR membrane system, producing high-quality purified water.
