Nanofiltration Membrane for Water Treatment Market – View in Detailed Research Report

Nanofiltration membranes are specialized separation barriers that operate at the molecular level, typically featuring pore sizes in the nanometer range (approximately 1‑10 nanometers). This configuration enables the removal of divalent ions, organic macromolecules, and micropollutants while allowing monovalent ions to pass more readily than reverse osmosis, positioning nanofiltration as a critical technology for water softening, color removal, and reduction of natural organic matter.
