Review of Organic Nanofiltration Membrane Technology
Nanofiltration, as a pressure-driven membrane process situated between reverse osmosis and ultrafiltration, has advantages such as low operating pressure, strong selectivity, high separation efficiency, energy conservation, and environmental protection. Organic nanofiltration membrane, as a high-performance membrane with high chemical stability, good mechanical and thermal stability, can effectively solve the problems of membrane pore size and difficult control of membrane fouling. It has shown good application prospects in water treatment, food processing, pharmaceutical manufacturing, and separation of chemical products. The article analyzes the retention and separation mechanisms of organic nanofiltration membrane, including steric hindrance effects, Donnan effects, and dielectric repulsion effects. It discusses the preparation and modification methods of organic nanofiltration membranes, reviews the latest application progress in the fields of biotechnology, pharmaceutical applications, wastewater treatment, and organic solvent nanofiltration (OSN) membranes, and looks forward to its future development trends and challenges, aiming to provide a certain reference for the development of nanofiltration membrane treatment technology.
