Nanofiltration Membranes

Nanofiltration Membrane Technology

Nanofiltration is a membrane separation process that utilizes thin-film composite membranes with a porosity size of 0.1 to 10nm. Nanofiltration can operate at lower pressures and selectively reject ions based on size and charge.

AXEON's nanofiltration membranes offer varying ion rejection and flow rates for various applications. Our membranes are compliant with FDA standards and can be utilized in sanitary and industrial applications across many industries. Nanofiltration membranes allow water and some salts to pass through the membrane while retaining multivalent ions, low molecular weight molecules, sugars, proteins, and other organic compounds, while offering greater resistance to fouling. Nanofiltration membranes are also able to greatly reduce levels of hardness, nitrates, sulfates, tannins, turbidity, color, TDS, and moderate levels of salt from feed water streams.
