Q » How does nanofiltration differ from reverse osmosis?
03 Nov, 2025
A » Nanofiltration and reverse osmosis are both membrane filtration processes used in water purification. Nanofiltration removes small organic molecules, divalent ions, and larger monovalent ions, making it ideal for softening water. Reverse osmosis, however, removes a broader range of contaminants, including nearly all dissolved salts, bacteria, and viruses, due to its finer membrane. This makes reverse osmosis more effective for producing highly purified water, though it typically requires more energy.
