摘要：Membrane filtration assembly where the fluid to be filtered is recirculated onthe retentate side of a membrane filter and where the filtered fluid, i.e. the permeate, isrecirculated on the permeate side of the membrane filter in such a manner that the twostreams are cocurrently passed along the membrane filter. The membrane filtercomprises several membrane units (20) in form of tubular supporting structures, eachsupporting structure comprising one or more filter membranes (28). The membrane unitsare mounted in parallel inside a common housing in such a manner that one stream flowsinside the membrane units while the other stream flows in a space surrounding saidmembrane units. Each membrane unit is provided with a separate space (22) designed as anarrow passageway on the inner side defined by the membrane unit and on the outerside defined by a channel tube (18), the inner cross section of which is 4 to 200 % largerthan the outer cross section of the membrane unit. The assembly is easy to clean, and it iseasy to replace the individual membrane units.
