    Abstract: A fluid filtration apparatus is disclosed particularly usable with a perforate tubular fluid conduit as normally used for filtration of cleaning fluids and the like wherein the filtration apparatus includes a plurality of filter elements being generally cylindrical and defining a central channel therethrough to be adapted to receive the fluid conduit extending therebetween. Also included are a plurality of gasket assemblies positionable between adjacent filter elements to minimize passage of cleaning fluid therethrough to facilitate cleansing of the fluid. An outer retainer is utilized for compressing the individual filter element against the filter gaskets in such a manner as to provide a continuous filtration media along the entire length of the tubular fluid conduit and to prevent outlets for fluid emanating therefrom without passage through filtration media.

    Abstract: A filtering apparatus suitable for being cleaned by backwashing includes an outer housing (11) and an inner filter (13) disposed in the outer housing defining an outer annular flow passage (16) and an inner flow passage (17). The outer housing is tapered in relation to the external shape of the filter to provide a substantially uniform liquid velocity through the filter in both forward flow and backflow directions. The filter is made up of a plurality of ring-like segments (38) stacked end to end on which a filter medium (37) is mounted.

    Abstract: A filter device particularly directed to the straining of materials for coating paper products which device is provided with a tapered baffle element to particularly aid in the back flushing of the filter to provide cleaning thereof and said baffle having a plurality of arcuately spaced fin members thereon for supporting of a filter element thereabout. This filter element is formed of a replaceable material having a plurality of apertures therethrough which material is normally non self supporting and which material gains its filtering support and positioning by the finned structure which will support the filtering element in both the normal filter operation and the back wash operation.

    Abstract: 1,101,453. Filter aid filter. SEITZ-WERKE G.m.b.H. 19 Feb., 1965 [22 Feb., 1964], No. 7172/65. Heading B1D. A filter aid filter in which liquid to be filtered on entering the filter vessel 18 is initially directed away from filter elements 19 through ports 17 to reduce turbulence, comprises a horizontal filter vessel 18 containing a number of disc shaped filter elements 19 with their outlets connected in parallel, the elements 19 resting one behind the other on substantially parallel horizontal supports 15 (16) within the filter vessel and the supports being mounted in turn on a fixed or movable filter closure member (10) carrying liquid inlet ports (11, 12) and outlet ports (14), each support 15 (16), comprising a hollow conduit, closed at one end, with its open end in communication with an inlet port and having outlet orifices 17 substantially outside the circumference of the filter element for directing incoming liquid towards the vessel wall and hence away from the filter elements. Each filter element 19 may comprise fine wire mesh stretched on frames and peripheral eyelets (21) which when joined together form a fluid outlet manifold from the elements. The pressure drop in the conduits in supports 15 (16) may be equalized by different cross-sections or changing the spacing of the orifices 17. The filter aid material may be asbestos fibres. Numbers in brackets refer to Fig. 1 (not shown).

    Abstract: An outside-in liquid purification system includes a housing and a cartridge. The housing defines an interior space and includes an inlet, an outlet, walls extending between a top side and a bottom side, and an unfiltered volume. The cartridge is disposed within the interior space and includes a top cap adjacent the top side of the housing configured to direct liquid that enters the interior space to the unfiltered volume and a filter having an annular shape and extending between the top cap and the bottom side of the housing such that no portion of the unfiltered volume is below the filter with the filter defining a hollow vertical column such that liquid flows from the unfiltered volume through the filter into the column and then downward out of the housing through the outlet.
