Membrane Systems
Nanofiltration System
Nanofiltration (NF) represents a sophisticated membrane separation technology positioned between ultrafiltration and reverse osmosis in terms of selectivity. This advanced technique uses specialized semi-permeable membranes to selectively remove larger organic compounds, small molecules, and divalent ions from liquids.
Widely utilized across biotechnology, dairy, pharmaceutical, nutraceutical, and food processing industries, nanofiltration provides precise separation control that enables concentration and purification of target substances while retaining desired components in treated liquids.
Sanitech Engineers produces exceptional nanofiltration membrane solutions with systems meeting all international regulatory standards.
