Ultrafiltration System. Location: Home >Products Ultrafiltration System 切换布局 Ultrafiltration System Brief UF is a method that physically removes particles of a certain size using the porous material. In the UF process the solution is pushed through the semipermeable membrane with a pore size of 0.005-0.1μm. Large particles and contaminants with high molecular weight are retained. At the same time, water and solutes with low molecular weight pass through the membrane. Industrial Ultrafiltration (UF) Membranes Systems Ultrafiltration is a pressure-driven membrane separation process that removes suspended or particulate matter (including colloids & silt) from water. Ultrafiltration is more reliable than conventional multimedia filtration that removes particles of 10 microns in size or larger. Ultrafiltration also efficiently removes bacteria and most viruses.
