The MBR membrane element comprises thousands of hollow fibers, generally made of PVDF, and the membrane pore size usually is between 0.03 microns to 0.5 microns. The pore size is also slightly different according to different processes and membrane fiber materials during production. The following article will explain the relevant knowledge about the pore size of MBR membranes.
What is the Filter Precision of MBR Membrane?
The fibers’ pore size determines the MBR membrane’s filtration precision. The smaller the pore size, the higher the filtration accuracy. The common MBR membrane elements on the market are microfiltration and ultrafiltration membranes. The filtration precision of microfiltration is between 0.1 – 0.5 microns, and the filtration precision of ultrafiltration is between 0.01 – 0.1 microns.
What substances can be filtered by the MBR membrane?
MBR membranes can filter substances including hair, emulsions, colloids, algae, bacteria, viruses, and other invisible particles. Of course, it can also filter substances with larger molecular diameters, such as sand particles and sawdust. However, we recommend adding a first-level security filter before the MBR membrane to filter out large particles and avoid sharp substances from damaging the membrane elements.
What are the Applications of the MBR membrane？
MBR membranes are widely used in water treatment. The following are common MBR membrane applications:
- Municipal Sewage Treatment
- Industrial wastewater Treatment
- Chemical, textile wastewater treatment
- Electronic wastewater treatment
- Garbage wastewater treatment
- Biochemical wastewater treatment
- High concentration organic wastewater, high SS wastewater treatment
Above is the knowledge about the pore size of MBR membranes. Knowing the pore size of the MBR membrane can help you choose the best filter for your needs. If you have any related questions, please don’t hesitate to contact SPERTA.
