Abstract: Filter cartridge designs for use in conjunction with valves of the faucet or spigot type for withdrawing liquids at relatively low pressures from containers such as gravity feed jugs, ice chests, coolers, collapsible travel bags, and the like, wherein the filter cartridge housings have various shapes and attachment schemes to the spigot subassembly.

Abstract: The present invention presents a filtration system with an integrated manifold valve. The filtration system employs only one pivotal component—the pivoting of the manifold. The manifold valve includes a dual aperture design for a two-fold alignment scheme with the ingress and egress lines of the fluid source. The invention is free of multi-component rotary valve with internal, rotatable parts, or an activation component, such as a handle, for initiating the rotary valve, allowing the user to rotate the rotational components thereof. The reduction in moveable components in this design reduces the likelihood of failure and increases the reliability of the filtration system.

Abstract: A gravity filter media fabricated from multiple spiral wound or pleated layers, where different layers are designed for specific contaminant removal process and the layers are combined into a single pack for ease of use. The layers or fiber sheets are chemically treated for contaminant removal, with different layers having different chemical treatments, or the layers are immobilized with particles of various sizes for use as low contact-time adsorbents, with different layers having different immobilized particles, or the pore structure is varied from one fiber sheet to another—one being a tight pore structure, and the other being a more open pore structure, or any combination thereof. When using immobilized particles, the immobilized particles can be chemically treated for the specific removal of targeted contaminants, and multi-layered for custom designed removal of specific contaminants.

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: 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 or in 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 method for forming and immobilizing small particles on a filter substrate using a first and second polymer solution, a solution of sodium bromide and a solution of a metal salt. The method adjusts the pH of at least one of the first and second polymer solutions, immersing the filter substrate in the first polymer solution and immersing the filter substrate in the second polymer solution. The method includes repeating the steps of immersing the filter substrate in the first solution and the second solution alternately until desired number of layers is achieved. The method allows for the filter substrate to be immersed in the solution of the metal salt and subsequently in the solution of sodium bromide.

Abstract: This invention relates to an anti-scale water treatment system, composition and related methods. The system suppresses hard scale formation by releasing small amounts of transforming agent into water.

Abstract: An activated carbon filter with reduced leachable arsenic comprising activated carbon, a binder material for binding activated carbon into a filtration mesh and an arsenic adsorbent in a concentration of less than about 5% for reducing leachable arsenic inherent in the activated carbon.

Abstract: A method of reclaiming brine waste in a water softener having an inlet, a service water outlet, a wastewater outlet, and having a brine/rinse cycle in which brine solution is directed through a resin bed and to a drain, includes measuring a TDS or specific ion level of the solution exiting the wastewater outlet during the brine/rinse cycle, comparing the measured TDS or specific ion level with a preset value, and diverting the flow of water out the outlet to a reclamation location once the measured TDS exceeds the preset value. A waste reclamation unit includes a housing in fluid communication with the water softener and at least one waste reservoir, a compressor, a compressor coil, a control unit configured for sensing the introduction of liquid into the reservoir and for triggering the compressor; and a collection pan configured for collecting water condensing on the coil and preventing the entry of water into the waste reservoir.

Abstract: Processes for deionization and demineralization of a fluid containing ions comprising:(a) Loading an amine or ammonia buffer onto a first weakly acidic cation exchange resin to occupy cation exchange sites and to form a first bed comprising a first amine-buffered resin;(b) Passing said fluid containing ions through said first bed comprising said first amine-buffered resin and exchanging cations of said fluid for amine cations of said first amine-buffered resin to form a first effluent comprising an anion-buffer salt complex;(c) Passing said anion-buffer salt complex through a first weakly basic anion exchange resin where an anion portion of said anion-buffer salt complex is split from said anion-buffer salt complex by adsorption of said anion portion onto said weakly basic anion exchange resin to form a second effluent comprising buffer in free hydrated base form;(d) Passing said buffer in free hydrated base form to a second weakly acidic cation exchange resin where said buffer loads onto said second weakly a

Abstract: The method of purifying spent brine from the regeneration of ion exchange resin, for example resin in water softeners. The method comprises acidifying the spent brine to a pH of less than 3 with an acid other than sulfuric acid, which acid is preferably chosen from at least one acid which forms a calcium salt that is more water soluble than calcium sulfate. One passes the brine through a nanofiltration membrane to purify the brine by separating from it a waste stream which comprises the majority of the polyvalent ions present, so that the purified brine has most of its contaminating polyvalent ions removed.
