Abstract

A filter including a first flow path having a plurality of interconnected channels and a second flow path having a plurality of interconnected channels. The channels of the first and second flow paths are alternatingly configured in a substantially concentric pattern. A filter media is interposed between the channels of the first and second flow paths. A filter including a filter media arranged in a plurality of substantially concentric layers; a fluid outflow system contacting the entirety of one side of the filter media, and a fluid inflow system contacting the entirety of an opposite side of the filter media. A method of filtering a fluid including the steps of flowing the fluid along an inflow path having a fluid permeable core member in fluid communication with a plurality of inflow channels via an inflow conduit extending radially outward from the core member, passing the fluid through a filtration media, and collecting the fluid within an outflow path having a plurality of outflow channels in fluid communication with an outflow conduit extending radially inward toward the core member. The inflow and outflow channels are alternatingly configured in a substantially concentric …
