1. An apparatus for separating fluids into two fractions by means of semipermeable membranes comprising a stack of alternating guide plates and membrane supports, each membrane support supporting a semipermeable membrane on each side of the support so as to form flow passages extending parallel to the membrane surfaces, each of said guide plates being provided with apertures extending through the guide plates, liquid inlet means and liquid outlet means communicating with said flow passages extending parallel to the membrane surfaces and means for collecting and discharging liquid passing through said membranes, characterized in that the stack of guide plates and membrane supports comprises a longitudinally extending duct spaced apart from the apertures of the guide plates, and that each guide plate comprises at least one sealing member located within said longitudinally extending duct, said sealing members being mounted so as to form at least two longutidinally extending flow passages, one of said longitudinally extending flow passages being connected to the liquid inlet means, and the second longitudinally extending flow passage being connected to the liquid outlet means, some of said sealing members comprising supply channels connecting the first longitudinally extending flow passage with a flow passage extending parallel to the membrane surfaces and some sealing members comprising discharge channels connecting a flow passage extending parallel to the membrane surfaces with the said second longitudinally extending flow passage.
2. An apparatus as in claim 1, characterized in that the membrane supports and the guide plates are circular plates and each comprises a centrally located hole which holes are aligned so as to form said longitudinally extending duct and that the apparatus further comprises a bolt connected to end flanges at the end of the stack and mounted within said central duct so as to form a second longitudinally extending flow passage in the zone between the interior surface of said sealing members and the exterior surface of said bolt.
3. An apparatus as in claim 2, characterized in that each sealing member comprises a passage extending longitudinally of the stack, said passages forming together said first longitudinally extending flow passage.
