Abstract:
A system for membrane filtration by the cross-flow process, having a number of membrane modules, each including one membrane tube or a bundle (35, 35"") of a plurality of membrane tubes, whose walls have the function of separation membranes, and a tubular module housing (1-8, 1', 1"") for receiving the membrane tubes, delivering a medium to be filtered as a retentate and removing the filtrate in the form of permeate, wherein each membrane module has one connecting flange (20, 21) for delivering and removing the retentate and at least four further connecting elements (22-25), which are disposed laterally on the module housing (1-8, 1', 1"") and at least two of which act as connecting openings for removing the permeate; wherein the membrane modules are joined together laterally, via the connecting elements (22-25) , to form at least one group (16, 17, 16', 17') of membrane modules; and wherein the permeate of the membrane modules of each group (16, 17, 16', 17') is removed through the laterally joined-together membrane modules via the connecting elements (22-25).
