• Low fouling Hydrophilic Polyvinylidenefluoride (H-PVDF) membrane
• Excellent filtration performance with high flux
• Durable and break resistant double- walled fiber structure
• High chemical resistance and temperature tolerance for effective membrane cleaning
• Very fine nominal pore diameter (0.03 µm)
• High removal efficiency of bacteria and viruses
• Dead-end or concentrate bleed flow capabilities
• Outside-In flow configuration that allows for less plugging and higher solids loading, higher flow area and easier cleaning
• Can be periodically back washed and air scoured to improve performance and extend operating life by removing the fouling layer
• Simple, vertical, modular design allows low cost, compact systems

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 creates the perfect barrier without sacrificing performance.
