Hollow fiber ultrafiltration membrane is an ultrafiltration membrane made of hollow chemical fiber materials, which is a relatively complete and excellent ultrafiltration technology. The inner wall is covered with a microporous plate, and the diameter shows that the molecular weight of the substance can be intercepted, and the relative molecular mass can be intercepted from thousands to hundreds of thousands. The source water on both sides or inner wall of the hollow chemical fiber is pressurized and fluidized to form an external pressure type and an internal pressure type, respectively. Uf membrane module is the entire process of dynamic filtration, and the intercepted chemical substances can be removed as the concentration is small, will not block the membrane surface, and can run for a long time.
Ultrafiltration technology is a high-tech industry in the purification of crude salt, separation and concentration of aqueous solutions, obtaining effective chemical substances from industrial wastewater, and sewage purification treatment and reuse. It is characterized by simple application process, no heating, energy saving, low voltage operation, and small equipment area.
②. Handle with care and pay attention to maintenance. Because hollow fiber ultrafiltration membrane is a high-precision device, you must be careful when using and assembling. If you stop using it, you should rinse it with cold water first, and then add 0.5% formaldehyde aqueous solution for disinfection and sterilization, and it has good sealing performance. If winter parts need to be treated with cold protection, otherwise the parts are likely to be damaged.
③. Since each hollow fiber ultrafiltration membrane must be added with maintenance fluid before shipment, the protection fluid in the module must be thoroughly cleaned before use, first rinse with low-voltage (0.1MPa) water supply and drainage for 1 hour, and then use high-voltage (0.2MPa) Flush the water supply and drainage for 1 hour, regardless of whether it is low voltage or high voltage, all the drain valves of the system must be opened. When using water production, check and make sure that the commercial water does not contain any fungicides.
