ABSTRACT:
For the separation of suspensions in the form of liquid solid component mixtures with the aid of porous filter membranes or for the separation of suspensions free of solid components into the liquid components with the aid of solution diffusion membranes, a reduced pressure is produced on the permeate side of the membrane. For this purpose the permeate is sucked off by a jet pump and is transferred into a closed circuit flow in which it serves as a drive medium for the jet pump. The apparatus for performing the method includes a membrane filter arrangement (6) with a closed circuit conduit (11) connected to the permeate discharge conduit. A conveying pump (13) and a jet pump (10) as well as a collecting container (12) is arranged in the closed circuit conduit. The permeate discharge conduit is connected with the jet pump.
