    摘要: A method and system for decreasing the concentration of at least one metal in an aqueous solution. The metal may be molybdenum, tungsten, or both. An aqueous solution is introduced into at least one reaction zone, and at least one source of hydroxide ions is provided into the at least one reaction zone in an amount sufficient to precipitate at least some of the mass of the at least one metal. The aqueous solution includes a mass of the at least one metal and a mass of at least one reducing agent. The at least one reducing agent includes at least ferrous iron from at least one source of the at least one reducing agent. A composition of tungsten ferrite or molybdenum tungsten ferrite may be formed. The method may be used for purifying water, for the refining of metals, or to facilitate a chemical analytical determination.

    摘要: An appliance using water including an incoming water valve is provided. The appliance also includes a sensor disposed in-line to an incoming flow of water received from the incoming water valve and is configured to sense a degree of hardness in the incoming flow of water. The sensor includes a substrate and a sensing element disposed on the substrate. The sensing element includes a sensing matrix, an indicator for one or more chemical species in a flow of water, and a selectivity component that reacts reversibly with the one or more chemical species in the water. The sensor also includes a light source configured to direct light through the substrate and the sensing matrix. The sensor further includes a light detector configured to receive transmitted light from the substrate and the sensing matrix and to generate a signal representative of selective wavelengths of the light indicative of the one or more chemical species in the flow of water. The appliance also includes a cleaning volume, a drain for the cleaning volume and an additive valve for an additive used for cleaning. The appliance further includes a controller configured to receive a signal indicative of hardness of the flow of water from the sensor and output it to control the incoming water valve, the additive valve and the drain on the cleaning volume.

    摘要: System and method for purifying and recycling spent brine in a water softener are provided. The system may be made up of a cation exchange resin tank fluidly coupled for passing spent brine comprising monovalent and divalent ions. A fluid mixer valve is coupled to the resin tank and to a water tank to dilute the spent brine to a desired concentration of a regenerant salt, e.g., NaCl. An ion-separation device is fluidly coupled to the fluid mixer valve to receive the diluted spent brine and separate the diluted spent brine into first and second streams. The first of the streams comprises monovalent ions and the second of the streams comprises divalent ions.
