MBR is also known as Membrane Bio-reactor, which is a new water treatment technology combining Membrane separation unit and biological treatment unit. The removal rate of main pollution can reach: COD>93%, suspended matter and turbidity of producing water are close to zero, the water quality is good and stable, can be directly reused, realize the sewage resource water.
1). Better durability. Anti-oxidant modification on the in-let membrane surface makes it more durable in harsh environment like waste water.
2). Self-repairing function. Fine inner diameter of the membrane fiber can ensure that sludge blocks the membrane pore the instant the fiber is broken accidentally, endowing the membrane with self-repairing function without affecting outflow water quality.
3) High water flux. By modifying PVDF, the hydrophilicity of the membrane is greatly improved, the porosity of the membrane is more than 70%, and the flux of the membrane product is increased by more than 30%.
4) High separation accuracy. The membrane pores are uniform and dense, and it can be controlled within 0.03-0.1 μm separation aperture to ensure the filtration precision.
5) Long service life. The unique embedded braided tube structure has high strength, and effectively eliminates the phenomenon of broken filaments, the unique coating production process makes the membrane tightly combined with the inner braided tube, effectively avoid membrane peeling phenomenon, recoil resistance is greatly enhanced.
6) Strong chemical resistance. It can be more thoroughly chemically cleaned to better solve the problem of membrane fouling, high recovery rate of membrane flux and longer service life.
