The principle of nanofiltration is the same as that of membrane separation processes such as ultrafiltration and reverse osmosis. Nanofiltration is also a membrane separation process driven by pressure difference, which is an irreversible process. The separation mechanism can be described by the charge model (space charge model and fixed charge model), pore model, and electrostatic repulsion and steric hindrance models that have only been proposed in recent years. Compared with other membrane separation processes, an advantage of nanofiltration is that it can retain small molecular weight organics that pass through the ultrafiltration membrane, and can dialyze some of the inorganic salts retained by the reverse osmosis membrane—that is, it can synchronize "concentration" and desalination. conduct.
