NF 8040 NP030-31

Summary

Product identification

This document specifies the TurboClean® 8040-NP030-31, a Sanitary Style Nanofiltration (NF) element. It features a patented sanitary hard-shell design, which provides about 60% less bypass flow than other sanitary elements, leading to energy savings and/or higher flux rates. This design also results in more effective membrane cleaning, greater strength to withstand higher pressure drops, and easier loading/unloading due to tight OD tolerance and optimal circularity.

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.
• Cleaning: Elements must be cleaned periodically to ensure proper operation and prevent membrane damage. Refer to the Membrane Cleaning Guide – Food & Dairy: RO & NF Elements (TSG-C-003).
• Storage: Elements must be stored appropriately to ensure proper operation and prevent membrane damage. Refer to Element Storage Guides (TSG-O-009 & TSG-O-010).
• Warranty: Oxidation damage from agents like free chlorine in contact with polyamide membranes is excluded from warranty.
