The process of using membranes to separate, purify, and concentrate different components of a liquid is called membrane separation. Membrane separation technology refers to the selective separation of mixtures of molecules of different particle sizes at the molecular level when they pass through a semipermeable membrane. Membrane separation technology has the characteristics of low energy consumption, good selectivity, and strong adaptability.
