Product Water

The NFX membrane offers stable flux and a wide range of rejection for monovalent and divalent ions, operating at lower pressures than Reverse Osmosis membranes.

• Typical Operating Flux: 20-25 GFD
• Min Lactose Rejection: 99.0% (Test Conditions: 2% Lactose solution at 110 psi (760 kPa) operating pressure, 77°F (25°C))
• Min MgSO₄ Rejection: 99.0% (Test Conditions: 2,000 ppm MgSO₄ solution at 110 psi (760 kPa) operating pressure, 77°F (25°C))
• Average NaCl Rejection: 40.0% (Test Conditions: 2,000 ppm NaCl solution at 110 psi (760 kPa) operating pressure, 77°F (25°C))

Common Applications

• Demineralization & concentration of lactose
• Dye & optical brightening agent concentration
• Seawater sulfate removal
• Reduction of hardness, nitrates, sulfates, tannins, turbidity, color, TDS, and moderate levels of salt from feed water streams.

Mechanical / Hydraulic

Element Dimensions & Weight

See the official PDF for exact tabulated values, including Diameter (B), Length (A), PWT ID/OD, Tube Extension (C), and Dry Weight for various models (e.g., 1812F, 2540F, 2540M, 3838, 3838.75, 8038, 8040).

NF Membrane Area

See the official PDF for exact tabulated membrane areas in square feet for different feed spacer sizes (24, 31, 46, 65, 80 mils) across various element models.

Recommended Element Cross Flow Rate

The recommended cross flow rate will be subject to differential pressure limitations and specific applications. See the official PDF for exact tabulated values in m³/hr and gpm for different feed spacer sizes across various element models.

Elements can be designed to fit specific needs; custom specifications include element outer diameter (OD) or vessel/housing inner diameter (ID), element inner diameter (ID), and length. Elements are available with or without a controlled bypass tail, and additional feed spacers are available.
