ABSTRACT:
A stacked membrane disk module has a number of membrane disks interleaved with seal rings and includes a biasing subassembly for maintaining a compressive force between the membrane disks and interleaved seal rings so that the module can be repeatedly pressurized/depressurized. The membrane disks preferably include a central first aperture and a pair of second apertures which are radially spaced from the central first aperture. These apertures will thus be respectively registered when a number of such membrane disks are stacked between a pair of end plates so as to establish a central fluid passageway and a pair of second fluid passageways. A rigid perforated tube is positioned within the central fluid aperture and is connected to the end plates so that at least one of the end plates is capable of being axially displaced relative to the perforated tube. A biasing member (e.g., a compression spring, stack of truncated conically shaped washers or the like) may thus be concentrically positioned around the perforated tube so as to exert a bias force onto one of the end plates capable of axial displacements and thereby cause a compressive force to be exerted against the membrane disks in the stack.
