Important qualifications
- ¹ Depending on feed water quality and operating conditions.
- ² Temperature, pH limits and cleaning procedures are further detailed in the iSep 500+ User Manual.
Start-up, cleaning & storage
The manufacturer recommends an operational sequence incorporating permeate production, backwash, cleaning and module draining. Clean routinely via backwash, chemically enhanced backwash (CEB) and clean-in-place (CIP) to ensure proper operation and prevent membrane damage. Store appropriately to ensure proper operation and prevent membrane damage.
