The former is isotropic, no skin, pore is the same in all directions, belonging to in-depth to filter which has a dense surface and finger-like structures of the underlying surface thickness of 0.1 micron or smaller, and has ordered micro-hole, bottom 200~250 microns thickness, belonging to surface filtration. Industrial use of ultrafiltration membranes are generally asymmetric membranes. Ultrafiltration membrane material mainly cellulose and its derivatives, polycarbonate, PVC, PVDF, poly sulfone, acrylic, polyamide, polysulfone amide, sulfonated polysulfone, cross-linking polyvinyl alcohol, modified Acrylic polymers, and so on.
