ABSTRACT:
A module for crossflow filtration, a method of making same, and a filtration device that accommodates at least one such module, which includes at least two multilayer filter units which are stacked on top of one another and are separated from one another by a respective spacer, with the module having at least one channel for unfiltered material and at least one filtrate channel that connects the filter units. The module further includes a sealing material ring for sealingly interconnecting peripheral portions of the filter units, with at least one edge section of the filter units being spaced from the sealing material ring to form the channels for unfiltered material. The layers of each individual filter unit are fused together at least at edge sections that are not embedded in the sealing material ring which, at edge sections of the filter units that are embedded therein, has a width that is sufficient to completely accommodate the filtrate channels.
