Summary
Product Identification
- Product Name: TRISEP® SBNF
- Membrane Type: Cellulose Acetate (CA) Nanofiltration (NF) Membrane
- Date of Specification: 07/01/2021
- Description: TRISEP® SBNF is a cellulose acetate / triacetate nanofiltration membrane designed to deliver excellent color removal and total organic carbon (TOC) reduction in streams high in natural organic matter (NOM) while operating at very low pressure. It offers excellent organic removal along with the stable operation, cleanability, and long life of proven cellulose acetate chemistry.

Operational Notes
- 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. Refer to the Element Start-Up Guide – System Start-Up (TSG-O-005) for detailed procedures.
- Cleaning: TRISEP® membrane elements require periodic cleaning to ensure proper operation and prevent membrane damage. Refer to the Membrane Cleaning Guide – Cellulose Acetate Elements (TSG-C-005).
- Storage: TRISEP® membrane elements must be stored appropriately to ensure proper operation and prevent membrane damage. Refer to the Element Storage Guides (TSG-O-009 & TSG-O-010).
