Appl. No.:

09/688509

Inventors:

Roger P. Reid - Caldwell ID 83605

International Classification:

B01D 2708

US Classification:

210232, 210439, 210440, 210443, 210444, 210450

Abstract:

A filter assembly is described that includes a substantially recyclable filter cartridge inside a pressure vessel. The invented filter cartridge comprises substantially non-pressure bearing walls, except for a pressure-bearing neck that is adapted to withstand high pressures preferably in the range of about 500 psi from the inside. The walls of the filter cartridge that are incapable of withstanding significant internal pressure are surrounded on the outside by a pressure vessel. The invented cartridge need not seal to the pressure vessel, because the cartridge neck protrudes outside of the pressure vessel to seal directly to a filter head. The cartridge preferably includes a quick-disassembly mechanism for allowing quick and non-destructive access to the internal components and media of the cartridge.

Abstract:

A filter assembly ( ) is described that includes a sub-stantially recyclable filter cartridge ( ) inside a pressure vessel ( ). The invented filter cartridge comprises substantially non-pressure bearing walls, except for a pressure-bearing neck ( ) that is adapted to with-stand high pressures preferably in the range of about 500 psi (34,47. 10 Pa) from the inside. The walls of the filter cartridge that are incapable of withstanding significant internal pressure are surronded on the outside by a pressure vessel ( ). The invented cartridge need not seal et the pressure vessel, because the cartridge neck ( ) protrudes outside of the pressure vessel ( ) to seal directly to a filter head. The, cartridge preferably includes a quick-disassembly mechanism for allowing quick and non-destructive access to the internal components and media of the cartridge.

Abstract:

Embodiments of a key system for filters and their connecting heads/holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding âkeyâ and one being a recessed âlockâ. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mismatched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.

Abstract:

Embodiments of a method and filter apparatus ( ) for filtering and/or treating water are shown and described, each embodiment being for multiple-stage processing of water or other liquid, with storage intermediate between the stages. Preferably, water is passed through a first zone ( ) of a filter housing cavity and conducted through an intermediate port ( ) to storage ( ). When water is demanded by a usage device ( ), water flows in reverse from storage back into the filter ( ), to flow through the second zone ( ) for a second stage of filtering/treatment, and then preferably out an outlet port ( ) to the usage device. Water may also flow from the water source directly through the first and second zones ( ) and to the usage device ( ), without intermediate storage. Preferably, both first and second zones are contained and axially arranged within a single filter housing ( ). Preferably, water flows bi-directionally through a central return tube ( â), or other axial passage ( â) through the first zone media that connects to a combined outlet-inlet intermediate port ( ) in or near the housing top wall, so that this tube or axial passage may be used as the collector for the first-zone effluent and also the distributor for the second zone feed.

Abstract:

A bracket system holds one or more filters in quick-attach and quick-release fashion. Bracket modules are combined in modular fashion, with tubing or other conduit between the modules, to create a âbankâ of filters easily changed in number, arrangement, and flow scheme. Preferably, the bracket system comprises pairs of top modules and bottom modules that capture and support the top end and bottom end of a filter. Filter inlet and outlet ports preferably slide onto and off of cooperating tubes or ports in the bracket modules, for installation and removal of the filters onto/from the modules without tools or threaded connections. A top retaining member preferably pivots off of its respective filter, so that the filter may be lifted up off of its respective bottom module. The bottom modules may be pivotal, so that lifting the filter up from the bracket system is facilitated by allowing the filter top end to also pivot out away from the top module. Each filter is preferably substantially vertically and pivotally removable from the bracket system.

Abstract:

A bracket system holds a filter(s) in quick-attach and quick-release fashion. Brackets are combined in modular fashion, with conduit between the brackets, to create a “bank” of filters easily changed in number, arrangement, and flow scheme. Top brackets and bottom brackets capture/support the top end and bottom end of a filter, respectively, and filter inlet and outlet ports preferably slide onto and off of cooperating tubes/ports in the bracket modules without tools or threaded connections. A retainer may pivot on and off of its respective filter, holding the filter in place and releasing the filter, respectively. After pivoting the retainer up from the filter, the filter may be lifted up off of its respective bottom module, so that the filter is substantially vertically and pivotally removable from the bracket system. A keyed system may ensure that only the appropriate filter fits into the appropriate filter holder, wherein the keyed system includes key protrusions and cooperating key recesses on the mating surfaces that form a fluid connection between the filter and the filter holder. Sets of holders and filters may be provided wherein each set has key structure at different radial locations on the members, so that filters from a particular set cannot be used with any other set's holder.
