APPARATUS FOR SEPARATION OF A LIQUID USING SEMI-PERMEABLE MEMBRANES |
摘要 |
An apparatus for the ultra or hyperfiltration of liquids to form a permeate fraction and a concentrate fraction includes a stack of membranes and membrane support plates. The stack includes two longitudinally extending main flow passages connected with a plurality of flow passages extending along the surfaces of the membranes. There is provided a device for blocking the flow of liquid from one main flow passage to the other in a zone around the center line between the two main flow passages. Ribs may be provided 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. |
