  • Publication number: 20100209316
    Abstract: An apparatus for producing a cleaning solution. Specifically, the apparatus of some embodiments includes a reservoir for containing sodium chlorite. A disposable ion exchange cartridge is placed in fluid communication with the sodium chlorite reservoir via a conduit. The ion exchange cartridge is selectively disconnectable from fluid communication with the sodium chlorite reservoir or from the conduit. Generally, the ion exchange cartridge will be disconnected and replaced when the ion exchange materials in the cartridge are depleted or exhausted. A catalyst can also be placed in fluid communication with the sodium chlorite reservoir. The catalyst can be contained in disposable or selectively disconnectable cartridge that can be easily replaced when depleted. In another aspect of the invention, a color comparison chart is positioned adjacent a conduit to allow one to compare the color of the solution to the chart and determine the concentration of the solution.

  • Patent number: 7767079
    Abstract: An amalgam separator for purifying a waste stream that contains a mixture of air and waste liquid. The amalgam separator contains filter media that comprises a sulfur-impregnated carrier and an ion exchange resin, wherein the ion exchange resin is present at a concentration of from about 25 to about 75 weight percent. During its operation, the amalgam separator separates the waste stream into air and waste liquid portions, purifies the waste liquid portion, and then combines the purified waste liquid portion with the air.

  • Patent number: 7767087
    Abstract: A system and method are disclosed for filtering liquid using a filter platform that is not rigidly affixed to a container containing the liquid to be filtered. The platform may be buoyant so that as liquid flows from one side of the platform, through a filter, and then to the other side of the platform, the platform may move, thus reducing the volume of a container or portion of a container that holds the unfiltered liquid. Alternatively, the platform may be heavier than the liquid to be filtered, may be either set in place on a support structure or else set on top of unfiltered liquid and allowed to sink downward as liquid is filtered. The system may further comprise a flexible membrane that allows two sections of liquid to be separated, even while the platform is moveable.

    Abstract: Apparatus, process and article for treating an aqueous solution containing a chemical contaminant. The process includes contacting an aqueous solution containing a chemical contaminant with an aggregate composition comprising an insoluble rare earth-containing compound to form a solution depleted of chemical contaminants. The insoluble rare earth-containing compound can include one or more of cerium, lanthanum, or praseodymium. A suitable insoluble cerium-containing compound can be derived from a cerium carbonate, cerium oxalate and/or a cerium salt. The aggregate composition can include more than 10.01% by weight of the insoluble rare earth-containing compound, and in a particular embodiment consists essentially of one or more cerium oxides, and optionally a binder and/or flow aid. Although intended for a variety of fluid treatment applications, such applications specifically include removing or detoxifying chemical contaminants in water.

  • Patent number: 7727402
    Abstract: A chromatography cartridge with a packed bed is manufactured from an inner and outer chamber, the inner chamber being in an insert that is slidable into the outer chamber with openings in each such that a slurry that is originally placed in the interior of the outer chamber flows into the inner chamber as the parts are being pressed into each other. During the assembly, the particles in the slurry are compressed to fill the smaller volume of the inner chamber and excess liquid is discharged through ports in both chambers. The construction allows for a highly precise and reproducible column filling process with a minimum of steps and operator intervention and thereby low cost and reduced error.

    Abstract: Nanoparticle-treated particle packs, such as sand beds, may effectively remove coal fines from aqueous fluids, such as contaminated water. A porous substrate treated with nanoparticles, such as alkaline earth metal oxides/hydroxides, transition metal oxides/hydroxides, post-transition metal oxides/hydroxides, piezoelectric crystals, and/or pyroelectric crystals, may remove a substantial portion of coal fines from an aqueous fluid. It is believed that the nanoparticles capture and hold the coal fines in the particle pack due to surface forces, including van der Waals and/or electrostatic forces. The nanoparticles may be applied to the substrate via a coating agent, such as alcohol, glycol, polyol, olefin, vegetable oil, fish oil, and/or mineral oil.

    Abstract: A reusable liquid chromatographic column consists of three parts, a column body with an integral outlet port molded on one end, a sealing insert with an inlet port, and a perforated cap providing downward force to compress the sealing insert into the column body. A wedge-like seal is employed to seal the connection between the sealing insert and the column body. Two filters on both ends of the column body are used to prevent escape of packing materials from the column chamber under pressure. Hand tightening is adequate to seal the connection by screwing the perforated cap onto the column body. The column is reusable due to its simple disassembling and reassembling processes. It is also disposable due to its inexpensive fabricating materials and manufacturing process.

  • Patent number: 7479221
    Abstract: A storm water treatment device that is installed under the grate of new or existing catch basins, and more commonly referred to as an insert. The catch basin decontamination apparatus has a universal housing and support ring that allows one design to fit most applications. Adjustable chains allow for proper position below grate and a semi-flexible molded or rigid deflector directs incoming drain water to the housing. A slip-on filter/absorber cartridge fits over a perforated drain tube, in the center of the housing, allowing the drain water to first pass through the filter/absorber media before exiting through the drain tube and out the bottom of the housing. The filter/absorber cartridge includes a variety of absorber materials that absorb oil and repel water. Activated carbon, microbes and other site specific absorbents can be used in the replaceable slip-on cartridge. A leaf pre-strainer helps prevent leaves and debris from entering the housing.

  • Publication number: 20090001011
    Abstract: A gravity-fed carbon block water filter in one embodiment includes a filter block comprising multiple sub-blocks each comprising filter media walls surrounding and defining a cavity for receiving fluid. Each of the sub-blocks is connected to at least one other of the sub-blocks by filter media of which the filter block is made. In one approach, the filter media includes about 20-90 wt % activated carbon, and about 5-50 wt % binder. In another approach, a lead concentration in a final liter of effluent water filtered by the filter is less than about 10 ?g/liter after about 151 liters (40 gallons) of source water filtration, the source water having a pH of 8.5 and containing 135-165 ppb total lead with 30-60 ppb being colloidal lead greater than 0.1 ?m in diameter. A gravity-fed water filter in other embodiments has no specified shape but achieves a FRAP factor of about 350 or less.

  • Patent number: 7441665
    Abstract: The water purification cartridge treats water with a halogen liberated from halogenated hydantoinyl resins and polymers, resulting in the safe, complete, and economical purification of non-potable water at low flow rates typically found in gravity feed filtration systems and at water pressures of less than 1 psig. The cartridge of the invention purifies non-potable water of bacteria, viruses, and some protozons without the need for additional power sources or risk to the consumer for exposure to chemicals that have been identified to have harmful, long-term effects. The cartridge described herein enables a gravity fed water purification system by combining the cartridge with conventional filters, such as porous diatomaceous earthen ceramic water filters or activated carbon filters packed either with granular activated carbon or block.
