Classification of membranes (two)

10.

Depending on the separation principle of separation and the driving force it can be divided into a microporous membrane, ultrafiltration membrane, a reverse osmosis membrane, nanofiltration membrane, dialysis membrane, electrodialysis membrane, pervaporation film

10.

The famous Japanese polymer scholar Shimizu Takeo divided the membranes into separation functional membranes (including gas separation membranes, liquid separation membranes, ion exchange membranes, chemical functional membranes), energy conversion functional membranes (including concentration energy conversion membranes, light energy conversion coating, film mechanical energy into electrical energy into the film, the conductive film), a biological functional film (including sensing membrane bioreactor, the medical probe membrane) and the like

10.

The basic function of the separation membrane is to selectively permeate or transport specific substances, such as particles, molecules, ions, etc.

Table 10-2 The separation process of several main membrane separations

Various membrane separation devices are mainly composed of membrane separators (membrane modules), pumps, filters, valves, instruments and pipelines
