DOW™ Ultrafiltration (UF) modules are made from high mechanical strength, PVDF
hollow fiber membranes. The modules provide excellent performance and industry
leading membrane area. These modules have the following properties and
characteristics:
• 0.03 µm nominal pore diameter for removal of bacteria, viruses, and particulates
including colloids to protect downstream processes such as RO
• PVDF polymeric hollow fibers for high mechanical strength and chemical
resistance providing long membrane life and reliable operation.
• Hydrophilic PVDF fibers for easy cleaning and wettability that help maintain long
term performance
• Outside-In flow configuration allowing a wide range of solids in the feed water
minimizing the need for pretreatment processes and reducing the backwash
volume compared to Inside-Out configurations U-PVC housing, helping to
eliminate the need for costly pressure vessels
The 2860 which is shorter in length is recommended for smaller systems and where
building height is of concern. The 2880 has higher membrane area for the same
footprint offering a more economical design.
DOW Ultrafiltration Modules can be used for a wide variety of treatment applications
such as surface water, seawater, and industrial and municipal wastewaters.
