MICRODYN SpiraSep™ 960 ultrafiltration (UF) modules feature a vacuum-driven, submerged, backwashable, spiral-wound membrane design. This unique design, with open feed channels, allows SpiraSep modules to handle the solids levels seen in high fouling water and wastewater streams. An advanced aeration process combined with periodic backwashing easily removes particulate matter from the membrane surface. The low net driving pressure of an immersed system minimizes energy costs and membrane fouling.

With a design built to handle high fouling water and wastewater streams, SpiraSep modules can eliminate the need for extensive pre-treatment for UF systems, such as clarifiers, thus reducing cost, complexity, and footprint.

Important Information

• Start-up: MICRODYN-NADIR recommends an operational sequence that incorporates permeate production, cleaning, and module draining steps. For a more detailed operational sequence, please see SpiraSep 960 Product Manual pages 10-11.
• Cleaning: SpiraSep 960 ultrafiltration modules must be cleaned routinely via backwash, chemically enhanced backwash (CEB), and clean-in-place (CIP) to ensure proper operation and to prevent membrane damage. Please see SpiraSep 960 Product Manual pages 12-15.
• Storage: SpiraSep 960 ultrafiltration modules must be stored appropriately to ensure proper operation and to prevent membrane damage. Please see SpiraSep 960 Product Manual pages 18-19.
