Nanofiltration (NF) sanitary spiral membranes are designed for advanced separation and superior performance in demanding hygienic environments. With pore sizes ranging from 0.001–0.01 microns, NF membranes provide precise removal of divalent ions, organic compounds, and larger molecular contaminants, while allowing for the retention of essential monovalent ions, such as sodium and potassium, to maintain the integrity of the liquid. Optimized for CIP/SIP compatibility and extended service life, NF membranes deliver consistent, high-quality water in applications across the dairy, food & beverage, pharmaceutical, and chemical industries, where stringent hygiene and product purity are essential.
