DOW FilmTec Hollow Fiber Ultrafiltration Membrane Modules
DOW’s SFP & SFD Series UF modules are built with robust outside-in PVDF fiber technology. The hollow fibers feature high clean-ability, low chemical consumption, high recovery, and a superior combination of mechanical properties and chemical resistance.
The SFD series of the DOW ultrafiltration modules are especially suitable for drinking water and are certified under NSF/ANSI Standard 61 for safe use in drinking water applications.

Benefits of DOW Ultrafiltration Modules
- Excellent removal of colloids, particles, bacteria, and viruses
- Protection of downstream equipment and processes such as RO
- High flux membrane
- High surface area for good packing density and small footprint
- Low chemical consumption
- High chemical-resistance PVDF that allows aggressive chemical use for treating challenging water when needed
- Long term performance from mechanically strong fibers, easy cleaning and wettability providing long membrane life and reliable operation
- Temperature tolerant for more effective cleaning
- High tolerance to feed solids
- Ability to treat challenging water with limited pretreatment
- 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

Features
DOW Hollow Fiber UF Module Features
The DOW™ Ultrafiltration module utilizes a double-walled hollow fiber (capillary) PVDF membrane which has a very small nominal pore diameter for PVDF material that allows for the removal of all particulate matter, bacteria and most viruses and colloids. Despite the small pore diameter, the membrane has a very high porosity resulting in a flux similar to that of micro-filtration (MF) and can effectively replace MF in most cases.
The DOW™ Ultrafiltration double-walled hollow fiber membrane is formed from high grade polymeric chemicals. The virtually defect-free, double-walled fiber membrane is much more robust and less prone to breakage than single-wall hollow fibers but due to the high pore distribution, does not compromise flux. The uniformity of pore size and outside-in flow ensures the DOW™ Ultrafiltration membrane createsa perfect barrier without sacrificing performance.
- 0.03 µm nominal pore diameter
- PVDF Polymeric Hollow Fibers For High Strength And Chemical Resistance
- Hydrophilic PVDF Fibers for Easy Cleaning And Wettability
- Excellent chemical resistance
- Long membrane life and reliable operation
- Outside In Flow Configuration
- U-PVC Housing
- Certified Under NSF/ANSI Standard 61 For Safe Use In Drinking Water Applications (SFD models only)
