What Is UF Membrane? Performance of UF Membrane and Advantages of UF Technology Ultrafiltration is basically a pressure-driven membrane process that separates by molecular weight. The UF membrane pore size is generally between 1 and 100 nm, and it can cut off substances with a molecular weight of 300 to 500,000 Daltons, including polysaccharides, biomolecules, polymers and colloidal substances. The nominal cut molecular weight of most UF membranes is generally defined as the smallest molecular weight at which the china membrane has a rejection of greater than 90%.
