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 “bank” 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.

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.

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 or cap with neck that is adapted to withstand high pressures preferably in the range of at least 200 psi, and more preferably at least 475 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: Embodiments of a key system for filters and their connecting heads, brackets, or other holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock”. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mis-matched 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: A body board including a leash and leash connector assembly for attaching the leash to the board. A handle assembly is connected with the board utilizing solely the leash connector assembly. The handle assembly includes a base and a pair of arms extending outward therefrom in substantially opposite directions. An opening is provided through the base that is arranged to engage the leash connector assembly for connecting the handle assembly with the body board.

Abstract: Granules comprise binder-agglomeratd active particles for liquid treatment or filtration. Each granule has a center core of a material that itself has binding properties without the addition of other binders or sprays or adhesives, or, alternatively, each granule comprirses a matrix of active materials stuck together with the binder. The binder structure preferably ranges from a non-uniform matrix of binder formed by heat-deformed binder particles, to a clump of binder particles generally retaining the original shape or the binder particles, to non-continuous connectors of binder between active particles. The invented two-part media has high surface area per volume of media, which, because the outer surface and inner void surfaces of the particles are preferably substantially covered with active particles, translates to high activity for the preferred treatment process.

Abstract: A filter for disinfecting non-potable water is disposed in-line in a water delivery pipe, such filter having a plurality of chambers. The first chamber contains biocidal resin which imparts a biocide residue to the water as it passes there-through to kill microorganisms. The water then passes through a turbulating disk to an extended contact time chamber of a selected volume to allow further contact time between the biocide residue and any microorganisms in the water. The water then passes through a 1-3 micron screen, which acts to retain protozoan cysts within the filter, and then passes through a biocide removal chamber containing medias which remove the biocide from the water. The water then passes through a chamber containing bacteriostatic media which acts to prevent back contamination from the effluent end of the filter.
