Ceramic membrane filtration technology

2020-10-26

Ceramic membrane filtration technology: ceramic membrane is a porous asymmetric membrane prepared by special process of alumina, titanium oxide, zirconium oxide and other materials. Ceramic membrane filtration is a "cross-flow filtration" form of fluid separation process: driven by pressure, the raw material liquid flows in the membrane tube, small molecules pass through the membrane, and the concentrated liquid containing macromolecular components is retained by the membrane, so that the fluid can achieve the purpose of separation, concentration and purification. Ceramic membrane filtration accuracy covers microfiltration and ultrafiltration. The filtration pore size range of microfiltration membrane is between 0.05μm and 1.4μm, and the filtration accuracy range of ultrafiltration membrane can be between 10KDa-50KDa. Technical characteristics:

1) multi-channel ceramic membrane, channel diameter 4mm, suitable for high concentration, high viscosity and other liquid system filtration and separation treatment.

2) It has a high tangential flow rate, reduces the concentration polarization phenomenon on the membrane surface, and stabilizes the membrane flux.

3) membrane material: carrier a-Al2O3 content> 99%(99 porcelain), the film layer is composite zirconium film, strong anti-pollution, easy regeneration and recovery

4) high mechanical strength, good wear resistance

5) PH tolerance range is wide, acid resistance, alkali resistance, organic solvent resistance and strong oxidant performance is good

6) easy to clean, can be high temperature disinfection, reverse flushing, suitable for sterilization filtration process

7) Long service life, some industries have a service life of more than 5 years, low overall equipment cost, and high cost performance

8) Automation, semi-automation, manual design system, operation of the main application areas
