Filtration module

摘要

A filtration module is provided that includes a filter member and a spacing member disposed in detached, contact engagement along a length of each member, such length extending about a longitudinal axis of a filtration module to define a concentric and detached plurality of filtration layers, and an interleaved, concentric and detached plurality of spacing layers, respectively. One or both of the plurality of spacing layers and plurality of filtration layers may provide a radially-inward directed force. The spacing member may be elastically deformed in the filtration module to apply a radially-inward directed force and a radially-outward directed force, wherein the filtration and spacing layers are retained in substantial fixed spatial relation. A retaining member may be located to engage an external side surface of the filtration module. A filtration module may be constructed by winding the filter member and spacing member about a longitudinal axis of the module.

1. A filtration module, comprising:
a filter member; and a spacing member, said filter member and said spacing member being disposed in detached, contact engagement along a length of each said member to define a predetermined configuration of the filtration module, said spacing member being preformed to include a plurality of undulations extending across a width thereof and along said length thereof; wherein said length of said filter member and said length of said spacing member each extend about a longitudinal axis of the filtration module to define a concentric and detached plurality of filtration layers, and an interleaved, concentric and detached plurality of spacing layers, respectively; wherein corresponding portions of at least some of said plurality of undulations are configured across a portion of said width, between opposite edges of the spacing member, to define notched portions, wherein said filter member is located within said notched portions; and wherein the notched portions of the spacing member define a plurality of channel portions along the interleaved, concentric and detached plurality of spacing layers; and wherein at least portions of adjacent filtration layers are located therewithin.
