Ultrafiltration is an advanced separation technique that has gained significant attention across various industries. It selectively separates particles and solutes based on their size using a semi-permeable membrane. The process utilises a size exclusion mechanism, only passing substances below a specific molecular threshold through the membrane while rejecting large impurities.
Ultrafiltration operates through pressure-driven membrane separation. The membranes have controlled pore sizes, ranging from 1 to 100 nanometers. Selecting an appropriate membrane pore size is crucial for achieving efficient macromolecules, colloids, suspended solids, and other particulates’ separation from a liquid stream.
