  • Patent number: 10808327
    Abstract: An electrochemical cell includes a cathode and an anode disposed in a housing. Each of the cathode and anode portions extending radially outward from a region proximate a central axis of the housing. A surface area of an active surface of the anode is greater than a surface area of an internal surface of the housing. A surface area of an active surface of the cathode is greater than a surface area of an internal surface of the housing.

  • Publication number: 20200129926
    Abstract: An electrochemical separation device includes a first electrode, a second electrode, and a cell stack including a plurality of sub-blocks each having alternating depleting compartments and concentrating compartments and each including frame and channel portions disposed between the first electrode and the second electrode. An internal seal formed of a first material is disposed between and in contact with the channel portions between adjacent sub-blocks in the cell stack and configured to prevent leakage between depleting compartments and concentrating compartments in the adjacent sub-blocks. An external seal formed of a second material having at least one material parameter different from the first material is disposed between and in contact with the frames of the adjacent sub-blocks in the cell stack and configured to prevent leakage from an internal volume of the electrochemical separation device to outside of the electrochemical separation device.

  • Publication number: 20190047883
    Abstract: A method of reducing the concentration of dissolved selenium in water includes introducing water having solid selenium-containing particles and a metal that bonds with selenium into a vessel and precipitating a metal-selenium compound from the water. A method of reducing the concentration of dissolved selenium or reducing dissolution of dissolved selenium, including providing a source of electrons into the water to precipitate dissolved selenium compounds is also disclosed. The precipitated compounds are separated from the water to produce decontaminated water. A system for reducing the concentration of dissolved selenium or reducing dissolution of dissolved selenium is also disclosed. The system includes a vessel fluidly connectable to a water source, at least one solid metal source, and a source of electrical voltage electrically connectable to the metal source.
