  • Patent number: 10241047
    Abstract: The invention relates to a method for analysing a sample comprising at least a first and a second scale inhibitor, which scale inhibitors are synthetic organic compounds comprising at least one ionised group. The method comprises optionally diluting and/or purifying the sample, and allowing the sample interact with a reagent comprising lanthanide(III) ion. The sample is excited at a first excitation wavelength and a sample signal deriving from the lanthanide(III) ion is detected at a signal wavelength by using time-resolved luminescence measurement. The total concentration of the first and the second scale inhibitor is determined by using the detected sample signal, and the concentration of the first scale inhibitor in the sample is determined. The concentration of the second scale inhibitor is determined mathematically by using the obtained results for the total concentration and for the first scale inhibitor concentration.

  • Publication number: 20140038266
    Abstract: The invention relates to a method of preparing an oil absorbent composition. The method comprises heating and then de-mineralising a precursor plant material under conditions suitable to produce an oil absorbent composition comprising charcoal. The invention extends to oil absorbent compositions per se, such as charcoal-based compositions, and to various uses of the compositions for efficiently and rapidly absorbing spilled oil, for example from water surfaces, or from bituminous sands.

  • Publication number: 20140027358
    Abstract: A system for dispensing water treatment compositions into a pool, spa, or other body of water is disclosed, which system provides a visible cue that the water treatment is properly dispersing and also provides a visible cue when the desired amount of water treatment has been dispensed. The system comprises a dispenser and the water treatment composition contained within the body of the dispenser, which dispenser and which system provides a readily visual cue that when the water treatment dose has been fully, or in some cases mostly or partially dispersed. For example, the dispenser sinks when fully dosed and resurfaces when empty, and in particular embodiments the water treatment comprises a means for generating visible gas bubbles and/or producing a color stream as the treatment dissolves.

  • Publication number: 20140021401
    Abstract: A water treatment agent for removing contaminants through oxidation with high-activity intermediate-state pentavalent manganese consists of a manganese-containing compound, a complexing agent, and a persulfate, wherein the manganese-containing compound is bivalent manganese ions, permanganate or manganese dioxide. The molar ratio of the bivalent manganese ions, the ligand, and the persulfate is 1:1-50:1-1000. The agent removes contaminants through oxidation with high-activity intermediate-state pentavalent manganese, and has the advantages of high oxidizing ability, being capable of fast removing organic contaminants in water, and having no toxic and harmful substance produced.

  • Patent number: 8591744
    Abstract: The current invention relates to composition and method for treating impurities in a circulating water system. The circulating water system impurities may be oversprayed paint in paint spray booth applications. The composition includes an aqueous solution of a cationized starch, a polybasic aluminum salt such as aluminum chlorohydrate or polyaluminum chloride and a solution of a medium to high MW aqueous flocculent. The composition is particularly useful when added to recirculating scrubber water in paint spray booths for effectively treating both water based and solvent based paints.

  • Publication number: 20130248447
    Abstract: A forward osmosis apparatus includes a diluting means for bringing a feed solution and a draw solution containing a cation source and an anion source in an ionized state into contact through a semi-permeable membrane and diluting the draw solution with water separated from the feed solution by means of the semi-permeable membrane; a separating means for separating the diluted draw solution into the cation source and anion source and into water; and a dissolving means, returning the separated cation source and the separated anion source to, and dissolving the cation source and anion source in, the draw solution that has been diluted. The molecular weight of the cation source in an uncharged state is 31 or greater and the Henry's law constant of each of the anion source and cation source is 1.0×104 (Pa/mol·fraction) or greater in a standard state.

  • Publication number: 20130187081
    Abstract: Presented herein are compositions including a linear tenso-active surfactant which, upon contact and mechanical stirring of a hydrocarbon body, induces emulsification, resulting in oxidation of fatty acid aliphatic bodies. The compositions solve the problem of hydrocarbon pollution. The hydrocarbon decomposer and its by-products dissolve hydrocarbons present in polluted bodies such as clays, soils, water and sand. Methods of the invention create a residue that is a fertilizer, at room temperature and with no need for high pressure.
