Patent number: 11851353Abstract: A water treatment system is disclosed having an electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.Type: GrantFiled: June 27, 2022Date of Patent: December 26, 2023Assignee: UGSI Solutions, Inc.Inventors: Brent A. Simmons, Gunnar T. Thordarson, James C. Robertson

Patent number: 10584888Abstract: Devices are provided for ventilating and/or removing volatile chemicals from liquid (e.g. water) stored in a liquid-containing storage tank (e.g. water-storage tank). The devices include a first fluid flow path that is physically isolated from a second fluid flow path and a convection device for moving a first fluid along the first fluid flow path toward at a desired destination and for exhausting the first fluid at the desired destination at a desired velocity. Methods are also provided for ventilating and/or removing volatile chemicals from liquid (e.g. water) stored in liquid-containing storage tanks (e.g. water-storage tanks). The methods involve blowing a first fluid through a ventilation device into a liquid-containing storage device at a velocity sufficient to achieve a desired mass transfer rate of volatile chemicals from the liquid in the liquid-containing storage device to air in the headspace and flowing the contaminated air back through the ventilation device.Type: GrantFiled: September 28, 2018Date of Patent: March 10, 2020Assignee: UGSI Solutions, Inc.Inventors: Peter Fiske, Robin Giguere, Ethan Brooke
