ABSTRACT:
A method for separating a liquid/liquid suspension with the aid of a solution diffusion membrane provides for producing such a reduced pressure on the permeate side that the permeate evaporates and that the permeate is then again condensated back into the liquid state. In order to require a small energy input and to provide advantageous conditions for a sterile operation, it is provided that the permeate passing through the membrane is subjected to the suction effect of a jet pump and that the evaporated permeate is condensed in the drive jet of the jet pump. The permeate is supplied into a closed circuit flow in which it functions as the drive medium for the jet pump.
