Important Information

• Start-up: MANN+HUMMEL Water & Fluid Solutions recommends flushing elements for 30 minutes at low pressure and discarding permeate during the flush prior to operation. A detailed start-up procedure is available in Element Start-Up Guide – System Start-Up (TSG-O-005).
• Cleaning: TRISEP® membrane elements require periodic cleaning to ensure proper operation and prevent membrane damage. Refer to Membrane Cleaning Guide – Water Application Elements (TSG-C001) for instructions.
• Storage: Appropriate storage of TRISEP membrane elements is necessary to ensure proper operation and prevent damage. Consult Element Storage Guides (TSG-O-009 & TSG-O-010).

MANN+HUMMEL Water & Fluid Solutions offers customizable specialty elements for challenging water and process applications.
