What are the types of MBR based on aperture?

In MBR process, the membrane is generally used as microfiltration membrane (MF) and ultrafiltration membrane (UF), and it is mainly used with 0.1 ~ 0.4mm membrane pore diameter, which is sufficient for the membrane reactor with solid-liquid separation.

Microfiltration membrane commonly used polymer materials: polycarbonate, and cellulose ester, polyvinylidene fluoride, polysulfone, ptfe, polyvinyl chloride (PVC), poly (ether imide), polypropylene, poly (ether ether ketone), polyamide, etc.

Ultrafiltration common polymer materials: polysulfone, polyether sulfone, polyamide, polyacrylonitrile (PAN), polyvinylidene fluoride, cellulose ester, polyether ketone, polyamide, polyether amide, etc.
