Ultrafiltration Systems

Pure Aqua, Inc. manufactures a full line of Ultrafiltration Systems. UF is a pressure driven membrane separation process that removes suspended or particulate matter (including colloids & silt) from water. This solution is far more reliable than a conventional multimedia filter, which removes approximately 10 micron or larger matter, where a UF membrane pore size ranges from 0.01 to 0.10 micron. In addition to superior turbidity removal, UF membranes efficiently remove bacteria and most viruses.

Ultrafiltration (UF) systems are systems having diverse membrane filtrations where hydrostatic pressure pushes solvents against a very fine membrane. They block suspended particulates and solids that are large while water and solutes with a lower molecular weight are allowed to flow through the membrane. Industry and research employ this separation process for purifying and concentrating macromolecular (103 - 106 Da) solutions, usually protein solutions. Ultrafiltration is similar to microfiltration, nanofiltration or gas separation, except it differs in the molecule sizes it blocks. To meet critical discharge criteria, ultrafiltration systems remove the need for clarifiers and multimedia filters. Effective ultrafiltration systems use membranes that can be immersed, back-flushable, and air scoured. Spiral wound UF/MF membranes offer excellent performance for the clarification of process water and waste water.

Ultrafiltration Systems provide the following advantages:
