DOW™ Ultrafiltration Modules

Ultrafiltration Modules (26 and 28 series) have been proven in hundreds of installations. Ultrafiltration (UF) is a pressure-driven membrane separation process that separates particulate matter from solutions; Ultrafiltration membranes reject particulates that are 0.03 microns and larger, facilitating high removal capability for bacteria, viruses, colloids, silt and more.

Ultrafiltration SFD-2880

Ultrafiltration SFD-2880 Modules are an ideal choice for systems with capacities greater than 50 m3/hr (220 gpm). With an 8-inch diameter and 80-inch length, together with an increase in packing density of 10,000 fibers, this module offers 77 m2 of active area. The Ultrafiltration SFD-2880 Module contributes to a more economical membrane system design. Ultrafiltration SFD-2880 Modules are made from high-strength, PVDF hollow fiber membranes.  Ultrafiltration SFD-2880 Modules have been tested and certified by NSF International under NSF/ANSI Standard 61 and under Standard 419 for Public Drinking Water Equipment (PDWE) for safe use in drinking water applications.
