  • Publication number: 20140027381
    Abstract: This invention discloses a kind of method to remove organic pollutants through coupling microwave degradation based on microporous mineral adsorption. It consists of the following major steps: Fill hydrophobic porous mineral adsorbent into the adsorption column to adsorb organic pollutants in the organic wastewater, and start up the microwave generator after the adsorbent reaches saturation so that the organic pollutants adsorbed inside the adsorption column can be degraded under microwave induction. With the alternative operation and regeneration of two adsorption columns, the organic wastewater can be treated continuously. In the invention, with the technologies of microwave-induced degradation through hydrophobic microporous mineral coupling adsorption, organic pollutants can be removed from water efficiently, and the degradation process and carrier can be circulated. The pollutants can be mineralized into non-toxic and harmless micromolecular substance completely.

    Abstract: Means for reducing an arsenic ion concentration in the solution to the degree of ultra trace amount are provided. Ammonium molybdate is supported by a nanostructure material by mixing the nanostructure material, which is obtained after the nanostructure material such as an alumina reacts with a surfactant, in the solution containing the ammonium molybdate. The nanostructure material supporting an arsenic ion adsorption compound such as ammonium molybdate can selectively adsorb and remove trace of arsenic ion in the solution by a room temperature treatment without a water conditioning such as pH control. In our removal system of arsenic, extra posttreatments are not needed because special pretreatments are not carried out, and special heating equipments are not used. Accordingly, our removal system of arsenic can be constructed at low cost. Furthermore, it can supply an arsenic-free solution by be constructed at multi stages.

    Abstract: Provided is a method for recovering high-concentration and high-purity amine from amine-containing waste water generated from nuclear power plants and thermal power plants. The method includes: capturing amine and concentrating waste water using a cation exchange resin; separating amine from the concentrated amine-containing waste water; and carrying out further separation of amine via distillation. The method may be applied to treat amine, which causes an increase in biochemical oxygen demand (BOD) and total nitrogen concentration, drastically at the time of its generation from waste water of nuclear power plants and thermal power plants. In this manner, the method may prevent an increase in load of existing waste water treating plants and avoid a need for modifying the equipment in the existing plants.

    Abstract: A water treatment system includes a weak acid cation resin where a portion of the feed water is exposed to the resin and then blended with untreated feed water to produce a stream of water with reduced mineral scaling and potential. Feed water is split into a first fluid stream, fed to a bypass conduit and a second fluid stream that is conveyed through a weak acid cation treatment bed. After passing through the bed, the treated fluid is combined with the bypass fluid stream to produce a blended feed water at the outlet. The ratio of the bypass fluid stream and treated fluid stream is a function of pH and L.S.I. A controller and associated sensors may control the relative flow rates between the bypass fluid stream and the treated stream to maintain a predetermined water parameter such pH, L.S.I., etc. within a predetermined range.

    Abstract: An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transport or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or postdisplacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds (30). A two-stage polish may be operated with modified lead/lag bottles. A detector (D) for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced.

    Abstract: A method of analyzing vitamin E components in a lipoprotein by subjecting a lipoprotein-containing sample to ion exchange chromatography to separate the lipoprotein, reacting the separated lipoprotein to a pretreating solution containing an organic solvent and a surfactant to liberate vitamin E components, and then subjecting the liberated vitamin E components to reverse phase chromatography. Also described is a method of judging various pathological conditions such as the pathological conditions of diabetes, the risks of coronary artery diseases, and the pathological conditions of myocardial infarction using levels of vitamin E components in the lipoprotein as an index.

  • Publication number: 20110220571
    Abstract: The present disclosure describes using the naturally present dissolved chemicals as precipitants from local water sources to form an adsorbent. The adsorbent may be collected and used at the right pH and temperature to purify and remove heavy metals from waste water. Once the heavy metals are removed the concentration of the heavy metals are estimated in the reusable water. The local authority acceptable level heavy metal containing reusable water is reclaimed for non-human consumption. This disclosure enables to conserve water and provide a cheap and an effective method to decontaminate industrial waste water.

  • Patent number: 8017020
    Abstract: It has been discovered that jet fuel containing enhanced thermal stability additives and water can be delivered with a final water content of 15 ppm or less via existing jet fuel distribution system by controlling the fuel flow rate through the fuel delivery system comprising one or more filter coalescers and separator systems, said controlled fuel flow rate being determined by passing a sample of actual fuel through a sample of the fuel filter at various fuel flow rates to identify the flowrate at which the fuel effluent contains 15 ppm or less.

  • Patent number: 7994379
    Abstract: A radioactive containment composition may be created for containing radionuclides from a radioactive material by mixing a clay mineral with water. This mixture may form an aqueous clay suspension. The mixture can be refined by filtering to remove coarse material. The aqueous clay suspension may be applied to a radioactive material, allowing the radionuclides to be exchanged with cations in the aqueous clay suspension. The resulting aqueous slurry, a silver-based solution may be added to produce a suspension. The suspension may be collected, heated and analyzed.

  • Publication number: 20110100917
    Abstract: Provided is a method for recovering high-concentration and high-purity amine from amine-containing waste water generated from nuclear power plants and thermal power plants. The method includes: capturing amine and concentrating waste water using a cation exchange resin; separating amine from the concentrated amine-containing waste water; and carrying out further separation of amine via distillation. The method may be applied to treat amine, which causes an increase in biochemical oxygen demand (BOD) and total nitrogen concentration, drastically at the time of its generation from waste water of nuclear power plants and thermal power plants. In this manner, the method may prevent an increase in load of existing waste water treating plants and avoid a need for modifying the equipment in the existing plants.
