Liquid separation, as one of the most basic separation methods, is still an indispensable step in product processing.

With the increasing application of continuous flow technology, the inconvenience of the traditional liquid separation method using a separatory funnel is gradually increasing, including but not limited to the fragility of glass, inconvenience in cleaning, uncertain cleaning costs, and the need to interrupt material transfer, which is time-consuming and labor-intensive. As a result, various membrane separation structures have been brought about. A phase separator is a device for separating multiphase flows, especially in power systems and chemical engineering. It is usually separated by gravity, centrifugal separation and filtration. A membrane phase separator is a device that uses a semipermeable membrane or other selectively permeable membrane to achieve separation of different phases or components.
