Spirasep 960 PVDF

Summary

Product Identification

The SpiraSep™ 960-PVDF Ultrafiltration Module features a vacuum-driven, submerged, backwashable, spiral-wound membrane design. This design allows it to handle high solids levels found in high fouling water and wastewater streams. Its advanced aeration process and periodic backwashing effectively remove particulate matter from the membrane surface. The low net driving pressure of the immersed system helps minimize energy costs and membrane fouling.

The modules aim to reduce the need for extensive pre-treatment like clarifiers, thereby lowering cost, complexity, and footprint for UF systems. They are designed to directly treat difficult water and wastewater streams, contributing to reduced capital and operational costs and simplified treatment processes.

Important Information

• Start-up: An operational sequence incorporating permeate production, cleaning, and module draining steps is recommended. Refer to SpiraSep 960 Product Manual pages 10-11 for details.
• Cleaning: Routine cleaning via backwash, chemically enhanced backwash (CEB), and clean-in-place (CIP) is essential for proper operation and to prevent membrane damage. Refer to SpiraSep 960 Product Manual pages 12-15 for details.
• Storage: Appropriate storage is necessary to ensure proper operation and prevent membrane damage. Refer to SpiraSep 960 Product Manual pages 18-19 for details.
