Abstract
A module for separating at least one component from a flowing mixture containing the same, includes a pair of end plates between which a plurality of stacked separation disks are positioned. The separation disks separate at least one component from the flowing mixture and defines a central passageway therethrough. A tensionable conduit is disposed in the fluid passageway to define a pathway for the separated component through at least one of said end plates and cause the end plates to exert a compressive force to the stacked separation disks in response to the conduit being tensioned. In preferred embodiments, the tensionable conduit includes a single or double helix spring which is machined along a major axial extent of its length. An adjustment nut may thus be threadably coupled to at least one (nonmachined) end portion of the conduit so as to adjustably tension the conduit and translate such tension into compressive force exerted to the stack of membranes by the end plates.
