Abstract: In one embodiment according to the invention, there is provided a filter device for liquid filtration, the filter device being in fluid communication with a plurality of liquid pathways, at least one pathway of the plurality of liquid pathways having a smallest equivalent fluid flow diameter of the plurality of liquid pathways. The device comprises a filter membrane (108) and a filter core (109) comprising at least one cross hole (110) in fluid communication with the filter membrane, each cross hole having an equivalent fluid flow, diameter. The sum of the equivalent fluid flow diameters of the at least one cross holes does not exceed the smallest equivalent fluid flow diameter of the plurality of liquid pathways.

Abstract: Pleated filtration media and filtration devices generally include a filter media radially disposed about the annular perforated inner core, the filter media comprising a plurality of circumferentially disposed linear pleats extending from the inner core to a constant height (h) defined by an outer diameter; and one or more intermediate pleats circumferentially disposed between adjoining linear pleats, wherein each one of the intermediate pleats has a height less than the constant height, and wherein the height of the intermediate pleats progressively decreases in a clockwise or a counter clockwise direction. Also disclosed are methods for increasing surface area of a pleated filtration media.
