Summary
Product identification
This document describes the NFG (600-800Da) Sanitary Nanofiltration Spiral-Wound Element. Synder Filtration’s Nanofiltration membranes are engineered to provide superior separation performance for various application needs. Known for stable flux and a wide range of rejection to monovalent and divalent ions, these NF membranes are developed specifically for specialty process applications.
NF Series Benefits
- Competitive flux as the current industry standard NF membranes
- Excellent MgSO₄ and lactose rejection
- Operate at lower pressures than Reverse Osmosis membranes and still achieve excellent rejection of divalent and multivalent ions
- NF membranes greatly reduce levels of hardness, nitrates, sulfates, tannins, turbidity, color, TDS, and moderate levels of salt from feed water streams

Technical Notes For element sizes not listed, please call or email Synder Filtration for details. Synder Filtration can design an element to fit exact needs – specify the element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are also available with or without a controlled bypass tail. Additional feed spacers are also available. Trials should be conducted to determine optimal application conditions.
