Important Information
- Start-up: It is recommended to flush elements for 30 minutes at low pressure and discard permeate during the flush prior to operation.
- Cleaning: Oltremare membrane elements require periodic cleaning to ensure proper operation and prevent membrane damage.
- Storage: Oltremare membrane elements must be stored appropriately to ensure proper operation and prevent membrane damage.
