Abstract
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.
