DOW™ Ultrafiltration Technology

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.
