FILTERS WITH IMPROVED MEDIA UTILIZATION AND METHODS OF MAKING AND USING SAME
First Claim
1. A solid profile filter block comprising multiple sub-blocks, each of said sub-blocks comprising filter media walls surrounding and defining a cavity for receiving fluid, and each of said sub-blocks being connected to at least one other of said sub-blocks by filter media of which the filter block is made.

Abstract
Multi-core solid profile filter media blocks include multiple sub-blocks, which may be formed by providing a block with multiple interior cavities extending deep into the block, to allow water to flow deep inside the filter block to access the media of the sub-block (in the case wherein the cavities are at the inlet to the block) or that allows water to be collected from each filtration sub-block (in the case wherein the cavities are at the outlet from the block). One or more indentations/spaces/gaps in the exterior surface of the block also may be provided to separate and extend between portions of the sub-blocks, so that substantially all of the filter media of a sub-block is accessible to fluid for filtration. This way, a filter block may include a large amount of media in a small cartridge or package volume, and the filter block may exhibit good flow distribution and low pressure drop. Sub-blocks of the filter block may be integrally formed together into the filter block, or may be directly connected, for example, preferably without any housing or internals clamping or fastening the sub-blocks together.

- 17. A solid profile filter block comprising a plurality of cavities in the filter block and forming internal surfaces for being in fluid communication with a fluid inlet or a fluid outlet of a filter cartridge, and the filter block comprising an external surface comprising at least one indentation extending into the filter block to be between at least two of said cavities, so that fluid flowing in an inside-out flow scheme, into said cavities and through the filter block, exits the filter block at the external surface including at said at least one indentation, and so that fluid flowing in an outside-in flow scheme, into the filter block through the external surface including the indentation, exits the filter block through said cavities.

28. A method of filtering a fluid, the method comprising:
-
providing a solid profile filter block comprising multiple sub-blocks, each of said sub-blocks comprising filter media walls surrounding and defining a cavity for receiving fluid, and each of said sub-blocks being connected to at least one other of said sub-blocks by filter media of which the filter block is made; and filtering said fluid by causing the fluid to flow across walls of the filter block by steps selected from the group consisting of;
supplying said fluid to the cavities of the sub-blocks so that the fluid flows through said walls and collecting filtered fluid at said exterior surface of said filter block, and supplying said fluid to the external surface of the filter block so that the fluid flows through said walls and collecting filter water in said cavities. - View Dependent Claims (29, 30, 31)
