description In an apparatus for the ultra or hyperfiitration of liquids. to form a permeate fraction and a concentrate fraction and comprising a stack of membranes and membrane support ptates, said stack comprising two longitudinally extending main flow passages connected with a plurality of flow passages extending along the surfaces of the membranes there is provided (a) means for blocking the flow of liquid from one main flow passage to the other in a zone around the centre line between said two main flow passages or (b) ribs having a height which increases when viewed in a direction from the central part towards the periphery of a membrane support plate with the object of obtaining an improved distribution of liquid over the membrane surfaces.
