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.
Abstract:
A multi-stage, modular water filter apparatus having at least first and second filter housings engageable with one and other, and each being engageable with a water inlet member, a water outlet member and a fluid filter cartridge for removing undesired components in a water supply.

PROBLEM TO BE SOLVED: To eliminate the need for strict size design and size control for a screen pack and a cartridge in a screen unit.SOLUTION: The screen unit 1 includes: a cylindrical cartridge 13 in which a plurality of communication through-holes 12 allowing resin to flow from the outside to the inside are provided at an outer circumferential surface of a support part 15 formed so as to have a constant outer diameter; and a cylindrical screen pack 14 having a mesh for filtering resin and supported by the support part 15 of the cartridge 13 by being mounted so as to cover the cartridge 13 from the outside. An inclined tapered engagement surface 21 having a diameter increased toward a base end side is formed on an outer circumference closer to the base end side than to an outer circumferential surface of the support part 15 in the cartridge 13. The screen pack 14 has a base end opened, and an engaged surface 22 pressed from the top end side toward the base end side and contactable along the engagement surface 21 of the cartridge 13 is formed on an inner circumference at the base end side of the screen pack 14.
