Patent number: 8252185Abstract: A water treatment apparatus includes a housing comprising multiple housing portions and a plurality of treatment sections disposed within the housing, each treatment section comprising at least one distinct particulate layer. The apparatus is designed so that no water pressure need be applied to force the water through the apparatus, as gravity pulls the water down through the filtering layers. Water may also be force fed through the treatment apparatus; when the water is force fed, the housing portions need not be vertically stacked, but may be configured in any suitable arrangement. The treatment sections are distributed through the various housing portions in logical groups to perform various kinds of filtering. The housing portions are detachable and sealably stackable in multiple configurations, thus passing water through more or fewer treatment layers, depending on the quality of the incoming water.Type: GrantFiled: August 18, 2008Date of Patent: August 28, 2012Assignee: Zero Technologies, Inc.Inventors: Rajan G. Rajan, Mathu G. Rajan

Publication number: 20120118829Abstract: Contaminants are removed from a quantity of contaminated liquid in a treatment reservoir (2,28) containing a carbon based adsorbent material capable of electrochemical regeneration. The adsorbent material is in the form of a bed supported on a plate (6) at the base of the reservoir. The bed is agitated for a period to distribute the adsorbent material in the liquid and adsorb contaminant therefrom. At the end of the period the agitation ceases, and the bed of adsorbent material is allowed to settle. The adsorbent is then regenerated, during or after settlement, by passing an electric current through the bed to release from the adsorbent gaseous products derived from the contaminant, in bubbles rising through the decontaminated liquid in the reservoir. Various methods of regenerating the adsorbent material are disclosed, as are apparatus in which the method can be applied.Type: ApplicationFiled: May 6, 2010Publication date: May 17, 2012Inventors: Nigel Willis Brown, Edward P.L.

Patent number: 8088949Abstract: L-cysteine-is separated from an L-cysteine-containing fermenter broth containing an oxidizing agent which is capable of oxidizing L-cysteine at pH<5, by contacting the L-cysteine-containing fermenter broth with an ion exchanger at a pH from 5 to 9, the pH in the fermenter broth becoming <5, and preferably <2. The L-cysteine binds to the ion exchanger and the bound L-cysteine is then removed from the ion exchanger by means of an eluant.Type: GrantFiled: February 6, 2008Date of Patent: January 3, 2012Assignee: Wacker Chemie AGInventor: Andreas Boehm

Patent number: 8088283Abstract: A fluid treatment device, system, and process are described that provide a filtered, metal-depleted (treated) fluid. The system includes two pairs of tanks that are piped and valved to allow one pair to fill/react while the other pair decants/discharges, which provides a continuous flow of metal-depleted (treated) fluid. Power requirements are minimal since fluid is pumped at a low head pressure. The design has applications in the potable water, industrial, mining, chemical and environmental sectors.Type: GrantFiled: May 29, 2009Date of Patent: January 3, 2012Assignee: Battelle Memorial InstituteInventor: Henry O. Pate

Publication number: 20110290732Abstract: The invention relates to a method for decontamination of a liquid effluent including one or more radioactive chemical elements to be eliminated including the following steps: a step of bringing into contact in a stirred fluidised bed, in a first zone of a reactor, of the said liquid effluent with solid particles able, by coprecipitation and/or adsorption and/or ion exchange, to capture and retain the said radioactive chemical element or elements, as a result of which a suspension of solid particles is obtained containing the said radioactive chemical element or elements; a step of settling, of the said suspension, in a second zone of the same reactor, where this second zone is separate from the first abovementioned zone, as a result of which a solid phase is obtained including the solid particles containing the said radioactive chemical element or elements to be eliminated, and a liquid phase with a reduced or zero content of the said radioactive chemical element or elements to be eliminated; and a step ofType: ApplicationFiled: October 26, 2009Publication date: December 1, 2011Applicant: Commissariat a l'energie atomique et aux energies alternativesInventors: Vincent Pacary, Yves Barre, Edouard Plasari, Olivier Cohin, Hervé Muhr, Claire Jaubert Cere

Patent number: 8043510Abstract: Methods and apparatus relate to treatment of fluids to remove mercury contaminants in the fluid. Contact of the fluid with active outer surfaces of particles magnetically separable from the fluid loads the particles with the mercury contaminants. Magnetic separation then removes from the fluid the particles loaded with the mercury contaminants such that a treated product remains.Type: GrantFiled: October 27, 2010Date of Patent: October 25, 2011Assignee: ConocoPhillips CompanyInventors: Erin Elizabeth Tullos, John Michael Hays, Roland Schmidt, Joe B.

Patent number: 8043509Abstract: Devices and methods for water purification are provided. An improved demister (70) for removing liquid or other particles from steam is disclosed. The demister can have adjustable outlets. In other embodiments, a demister apparatus is placed, at least partially, inside a boiler apparatus (310). Additionally, a filter flow indicator (401) that provides an optical indication of the efficiency of a water filter is also provided. The filter flow indicator has a viewable side passage that connects the input and output sides of a filter unit. A weighted object, such as a ball (440), can move up and down the side passage in response to the pressure differential in the filter system. The user can determine the status of the filter by viewing the location of the weighted object in the side passage. Additionally, a device and method of adding various minerals back to purified water in order to improve the flavor of the water is described.Type: GrantFiled: June 29, 2006Date of Patent: October 25, 2011Assignee: Sylvan Source, Inc.Inventor: Eugene Thiers

Patent number: 8039658Abstract: A method of removing trace levels of arsenic-containing impurities from raw triethylphosphate (TEPO) is disclosed. The method uses adsorption, or adsorption followed by a flash distillation. The method comprises contacting raw triethylphosphate (TEPO) with an adsorbent which selectively adsorbs the arsenic-containing impurities in the raw triethylphosphate (TEPO). The adsorbent is a base promoted alumina containing adsorbent represented by a formula: ZxWy; where x is the weight percentage of Z in the adsorbent ranging from 30% to 99.999%; y is the weight percentage of W in the adsorbent, and x+y=100%; Z is selected from the group consisting of alumina (Al2O3), magnesium-alumina based layered double hydroxide (MgO—Al2O3), alumina-zeolite, and mixtures thereof; and W is selected from the group consisting of at least one basic metal oxide, at least one basic metal carbonate, and mixtures thereof.Type: GrantFiled: July 25, 2008Date of Patent: October 18, 2011Assignee: Air Products and Chemicals, Inc.Inventors: Steven Gerard Mayorga, Heather Regina Bowen, Kelly Ann Chandler

Publication number: 20110168634Abstract: The present patent refers to a new procedure for the preparation of constant height calcite beds through the continuous dosing of calcite by gravity under water, along with the control of whatever turbid waters might be generated during use of the procedure. The procedure is characterized by the use of a structure of dosing cones that allows for the continuous dosing of calcite by gravity under water and directly onto the surface of the bed. It also incorporates a grid for supporting the dosing cones, a silo with a floor made up of these dosing cones, an inner perimetric spillway below the cone support structure, a filtering floor for the uniform distribution of water or air below the calcite bed and, finally, a turbid water collection and recirculation circuit.Type: ApplicationFiled: September 2, 2009Publication date: July 14, 2011Applicant: FUNDACION CANARIA CENTRO CANARIO DE AGUAInventor: Manuel Hernandez Suarez
