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-2860

Ultrafiltration SFD-2860 Modules are an ideal choice for systems with capacities greater than 50 m3/hr (220 gpm). The large, 8-inch diameter module offers high effective membrane area, contributing to a more economical membrane system design. The shorter, 60-inch length module offers higher efficiencies over a wider range of feed water conditions compared to longer modules and also makes it an ideal choice for containerized system designs.  Ultrafiltration SFD-2860 Modules are made from high-strength, PVDF hollow fiber membranes. Ultrafiltration SFD-2860 Modules have been tested and certified by NSF International under NSF/ANSI Standard 61 for safe use in drinking water applications.
