Separation efficiency – definition, calculation

Separation efficiency. Separation efficiency describes the effectiveness of a separation process in process engineering. Separation efficiency defines the ratio of the amount of material separated in the system (filter or centrifuge) to the amount of material to be separated entering the system. An example is the amount of solids in a liquid.
