Ultra-filtration (UF) is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. A semipermeable membrane is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Once considered a viable technology only for desalination, membrane processes are increasingly employed to remove bacteria and other microorganisms, particulate material, and natural organic material, which can impart color, tastes, and odors to the water and react with disinfectants to form disinfection byproducts (DBP). As advancements are made in membrane production and module design, capital and operating costs continue to decline . The ultrafiltration membrane only allows the solvent (such as water molecules), inorganic salts and small molecular organic substances in the solution to pass through, and the macromolecular substances such as suspended matter, colloid, protein and microorganisms in the solution are intercepted,thereby achieving the purpose of purification and separation in ultra filtration plant application.
The advantage of ultra filtration plant:
1. The equipment has high filtration efficiency and good effect.
2. The system of ultra filtration plant has low energy consumption and short production cycle. Compared with traditional process equipment, the equipment has low operating cost, which can effectively reduce production costs and improve economic benefits.
3. The system has advanced process design, high degree of integration, compact structure, small floor space, easy operation and maintenance, and low labor intensity.
4. The control system of ultra filtration plant can be personalized according to the user’s specific requirements, combined with advanced control software, on-line centralized monitoring of important process operating parameters, to avoid manual misoperation, multi-faceted to ensure long-term stable operation of the system.
