Ultrafiltration membrane structure symmetric and asymmetric division. The former is the isotropic hollow fiber membranes Taian, no skin layer, the porosity is the same in all directions of the hollow fiber membranes, below the depth filtration; the latter has a more dense surface layer and the main structure to the bottom of the finger, the thickness of surface layer 0.1 microns or less, and having orderly arranged micropores, substrate thickness of 200 to 250 microns below the surface of the filter. Industrial ultrafiltration membrane used is generally asymmetric membrane. Ultrafiltration membrane materials are cellulose and its derivatives, polycarbonate, polyvinyl chloride, polyvinylidene fluoride, polysulfone, polyacrylonitrile, polyamide, polysulfone, sulfonated polysulfone, cross-linked polyvinyl alcohol, modified acrylic polymers and so on. Ultrafiltration using ultrafiltration membrane pressure difference driven membrane filtration method for ultrafiltration. Most ultrafiltration membrane from cellulose acetate fibers or the like of the polymer material and its performance was obtained. Most suitable for separating solutes in solution and enriched, but also other separation techniques commonly used in the separation of the colloidal suspension is difficult to complete, and its field of application is increasing. Welcome Jun Xin environmental technology products! As an advantage PVDF membrane materials: ◆ extremely chemical stability, long-term use in highly corrosive wastewater does not deteriorate ◆ excellent antifouling property, contaminants accumulated on the membrane surface is not easy, very easy to clean ◆ strong oxidation resistance, can withstand continuous high concentration of chlorine in the water Binzhou hollow fiber membranes can also be used when a high concentration of the oxidizing agent to strip contaminants membrane cleaning times to MBR membrane characteristics and advantages: ◆ ◆ low energy ◆ excellent water quality very strong chemical stability and high mechanical strength, longer life stronger anti-pollution performance ◆ ◆ ◆ higher pollutant loads smaller footprint ◆ process reliability, simple operation, and more ◆ maintain high water utilization less, receive up to 99.5% of water utilization.
