Abstract:
Water filtration media having a charged material affixed directly to binder material used in the fabrication of the filter media. A microbiological interception enhancing agent is added to the binder directly. The media having a charged material and a microbiological interception enhancing agent both affixed directly on a binder material is then combined with core filter media and prepared as a filtration media. A filter is prepared from the treated filter media.
Abstract:
A filter assembly for fluid filtration having a push-activated lock and release mechanism. A push filter design activates a floating key lock upon insertion and extraction, where the filter key may be used simultaneously as a lock and as an identifier for particular filter attributes. The filter base may be situated inline, and in fluid communication, with influent and effluent piping, such as within a refrigerator. The filter housing assembly may be attached to, and removed from, the filter base by a push-actuated release. Upon insertion, the filter key shifts the filter lock longitudinally to receive interlocking segments. Upon extraction, the same axial push shifts the filter lock further to align the interlocking fingers within gaps that allow for easy extraction. The specific key lock design allows a user to identify and match certain filter configurations received by the mechanical support, and reject other filter configurations.
Abstract:
A filtration system interconnection structure having manifold with a rotatable manifold magnet of correlated magnets, a shroud with alignment tracks, an actuating valve for water ingress, and a filter cartridge having a rotatable filter magnet of correlated magnets, where the manifold magnet and the filter magnet are in magnetic communication with one another when the filter cartridge is inserted with the shroud, and are at least partially rotatably compatible, where the manifold magnet rotates with the filter magnet until the manifold magnet experiences a rotational stop beyond a predetermined rotation of the filter magnet, thus allowing the filter magnet to shift polarity with respect to the manifold magnet and present a repulsion force for removal of the filter cartridge from the shroud.
Abstract:
A single sheet water filter media for gravity filtration applications that improves flow performance over the product life while maintaining sufficient metal reduction, wherein at least two distinct density gradients of the single sheet form a physical barrier for capturing colloidal and insoluble contaminants, retaining the colloidal and insoluble contaminants until the contaminants become soluble in the fluid, and being removed by the single sheet' filter media. The single sheet filter overcomes the difficulties of dual- and multi- layer filters attributable to slower flow rate realized well before the rated lifetime of the product. The two distinct density gradients of the single sheet filter media are created by exerting a force on a liquid slurry, such force resulting in the separation of higher powder loading and fibers that compose the top and bottom density gradients, respectfully.
Abstract:
A carafe filter cartridge for reverse flow applications where the filter housing and filter media top end cap directs unfiltered fluid into the filter media annular cavity, through the filter media sidewalls. And the filter media bottom end cap prohibits egress, filter fluid from exiting through the filter media end or the annular cavity. Filtered fluid is instead directed out through apertures in the filter housing sidewall. The optimum ratio of annular cavity and/or top end cap orifice area to the respective perimeter is determined to remove the risk of detrimental fluid flow due to air bubble generation.
Abstract:
The present invention presents a removably secured seal for forming a second stage water-tight seal within a two stage cavity filter head assembly for mating with a complementary manifold having cylindrical (male) bayonet ports. The seal includes a base circumferential seal having a center aperture and sidewall members extending axially upwards from the base seal; the sidewall members being insertable within cavities or slots formed in the second stage recess cylindrical cavity sidewall.
Abstract:
A scale suppression media and methods of making augmented polyacrylate resin beads combined with a directing agent to facilitate the formation of calcite and aragonite forms of calcium carbonate, the directing agent deposited directly into said polyacrylate resin beads. A strong acid monovalent salt, such as a metal ion, is added to the polyacrylate resin, and is adapted to be time released, and templates the calcium carbonate in the influent to form crystals in the water with reduced deposition of scale on the surfaces of material in contact with the water. The pores of the resin are filled with metal templating agent, and the agent is released as the influent passes over the resin.
Abstract:
A collapsible bag or compressible bottle container for accepting, holding, and filtering fluid. Fluid is filtered upon entry to the container or filtered upon egress. The filter media resides either in a removable cap, or in a second fluid-tight compartment attached to, and in fluid communication with, the container body. A one-way valve with unique one-time connection to a fluid source mitigates potential contamination from container overuse. A second collapsible layer is used in conjunction with the collapsible bag to accept compressed air that provides rigidity for the container body.
Abstract:
A filter for removing soluble, colloidal, and insoluble particles from a fluid, including lead using a first filter media for filtering soluble material from the fluid, a second filter media, adjacent and in fluid communication with, the first filter media, for filtering soluble material from said fluid, wherein the first and second filter media create a physical non-soluble particle barrier at their interface for capturing non-soluble particles, that when retained at the interface, become soluble over time in the fluid, and are subsequently removed by the second filter media. At least one of the filter media can be fibrillated nanofibers that are loaded with finely subdivided media of powdered ion exchange resins. A third filter media may be placed between the first and second filter media to enhance capturing and dissolving the physical non-soluble particles.
Abstract:
An interconnection scheme between a filter cartridge and its corresponding manifold whereby a magnetic shear force is introduced to remove a blocking mechanism that would otherwise prohibit attachment. The magnetic shear force may also be employed to activate or deactivate a switch or valve, or engage or disengage an engagement mechanism relative to other components upon interconnection. The magnetic shear force is generated by complementary correlated magnet structures moved into close proximity to one another. The interconnection scheme may be a linear or rotational attachment of the filter cartridge with respect to the manifold. A valve assembly utilizing magnetic shear force may be employed to activate a bypass action between a manifold ingress port and egress port, thereby allowing water to flow when a filter cartridge is removed from the manifold and directing water to the filter cartridge when the valve assembly is activated.
