PCT No. PCT/EP94/02644 Sec. 371 Date Feb. 9, 1996 Sec. 102(e) Date Feb. 9, 1996 PCT Filed Aug. 10, 1994 PCT Pub. No. WO95/04559 PCT Pub. Date Feb. 16, 1995The present invention is directed to an arrangement for the elimination of substances by means of a membrane filter wherein the use is foreseen both in the blood cleaning procedures as well as in chemical and biotechnological separation techniques. The fluid containing the substances is run through the primary side of the membrane filter and the secondary side is flowed through by a adsorptive suspension which contains the substance binding particles. A pump drives the adsorptive suspension through the secondary side of membrane filter and causes in this way locally differentiable positive and negative transmembrane pressure differences whereby a local fluid exchange occurs and by means of which the active substances come into contact with the particles. Since the volume of the adsorptive suspension in the secondary circuit is held constant, the mean transmembrane pressure does not alter.
