  • Ultrafiltration Membranes | Industrial Ultrafiltration

    Ultrafiltration 101. Ultrafiltration is a pressure-driven process, where untreated water is forced against a semipermeable membrane. This membrane allows water molecules to pass through while screening out particles (colloids, bacteria, and so on), much like a sieve. Because these extremely fine membranes clog so easily, UF membrane systems are ...
