Patent number: 10995021Abstract: The present disclosure relates generally to oxidation of ammonia using electrochemistry. Methods and systems may include at least one sensor to measure the concentration of ammonia in the effluent and/or the concentration of chlorine gas in the effluent. Methods and systems may also include at least one controller in communication with the sensor and/or the anode to reduce the current density of the anode generating the chlorine, and/or to change the flow rate of the ammonia containing water entering the reactor.Type: GrantFiled: April 27, 2020Date of Patent: May 4, 2021Assignee: Xogen Technologies Inc.Inventors: Dorin Bejan, Craig Gagnon

Patent number: 9296629Abstract: Methods and systems for reducing a redox active contaminant in a waste stream in a waste treatment system involve performing a unit process of the waste treatment system by contacting redox active contaminant in the waste stream with oxyhydrogen-rich gas generated on-site by an oxyhydrogen gas generator that implements water dissociation technology. The oxyhydrogen gas generator involves applying a pulsed electrical signal to a series of closely spaced electrodes that are submerged in the waste stream to produce oxyhydrogen-rich gas from a water component of the waste stream. Operation of the oxyhydrogen gas generator in the waste stream may accomplish one or more unit processes for waste treatment, such as oxidation, stripping, floatation, disinfection, conditioning, stabilization, thickening, and dewatering, among others.Type: GrantFiled: December 21, 2012Date of Patent: March 29, 2016Assignee: Xogen Technologies Inc.Inventors: David Ritchie Van Vliet, Herbert Wallace Campbell, Stephen Barrie Chambers, Hector Alvarez-Vazquez
