Nanofiltration Membrane for Water Treatment

Nanofiltration (NF) membranes are a type of semipermeable membrane used in water treatment processes to remove contaminants, including small organic molecules, multivalent ions, and larger monovalent ions. They function between ultrafiltration and reverse osmosis in terms of pore size and rejection capabilities. NF membranes are effective in reducing hardness, removing color, and treating wastewater, providing a balance between high flux and selective permeability. They operate under moderate pressure and are beneficial for applications requiring partial desalination, water softening, and removal of specific contaminants without the high energy demands of reverse osmosis.
