Spirasep 960 PES

Summary

The SpiraSep™ 960 ultrafiltration (UF) modules are vacuum-driven, submerged, backwashable, spiral-wound membrane designs. They offer superior operating performance over conventional hollow fiber formats, especially for high fouling water and wastewater streams. The unique open feed channels and advanced aeration, combined with periodic backwashing, facilitate the removal of particulate matter. This design minimizes energy costs and membrane fouling through low net driving pressure, and can reduce the need for extensive pre-treatment such as clarifiers.
