  • Patent number: 11993521
    Abstract: This disclosure provides techniques for treatment of aqueous matrices using electrolysis to produce soluble metals. An aqueous matrix of interest is passed through an electrolysis device with at least one consumable electrode, which dissolves under applied current, transferring a desired reagent to the aqueous matrix of interest. In one embodiment, the electrolysis device is used in a water delivery network to passivate hexavalent chromium (Cr6) and/or convert it to trivalent chromium; the electrode can be made of food-grade metal tin, which is electrolyzed to form a stannous reagent, which then reacts with the Cr6. The disclosed techniques provide for Cr6 passivation without requiring the use of concentrated acids or other harmful substances. Long term reagent generation efficiency can be enhanced through the use of cleaning processes which maintain a fresh electrode surface in contact with the aqueous matrix of interest.

  • Patent number: 10450661
    Abstract: A method for using an electrochemical cell to continuously acidify alkaline water sources and recover carbon dioxide with simultaneous continuous hydrogen gas production. The electrochemical cell has a center compartment, an electrolyte-free anode compartment having a mesh anode in direct contact with an ion permeable membrane, an endblock in direct contact with the anode where the endblock provides a gas escape route behind the anode, an electrolyte-free cathode compartment having a mesh cathode in direct contact with an ion permeable membrane, and an endblock in direct contact with the cathode where the endblock provides a gas escape route behind the cathode. Current applied to the electrochemical cell for generating hydrogen gas also lowers the pH of the alkaline water to produce carbon dioxide with no additional current or power.

  • Patent number: 10207936
    Abstract: Various ultraviolet (UV) reactors and their methods of fabrication are disclosed. One exemplary process comprises forming a set of parallel channels in a slab of ultraviolet transparent material. The process also comprises providing a reactor substrate with an input manifold and an output manifold. The process also comprises joining the slab of ultraviolet transparent material and the reactor substrate. The input manifold, output manifold, and set of parallel channels are in fluid communication after the joining step. The process also comprises providing a planar ultraviolet light source isolated from the set of parallel channels by the shaped slab of ultraviolet-transparent material. The set of parallel channels and a defining plane of the planar ultraviolet light source are parallel in the assembled ultraviolet reactor.

  • Patent number: 10189727
    Abstract: A fluid purification system has cells whose purifying capability can be regenerated. Some of the cells are arranged in series to reach a high level of purification. An automatic valve network is controlled to cycle the cells in a way that levels the loads on each, thereby maximizing the service interval for replacing expired cells, enabling all of the cells to be replaced at the same time after having each contributing approximately equally to the purification load, and operated such that at any one time, at least one cell is regenerated so as to enable continuous up-time.
