Patent number: 11958762Abstract: Self-cleaning electrochemical cells, systems including self-cleaning electrochemical cells, and methods of operating self-cleaning electrochemical cells are disclosed. The self-cleaning electrochemical cell can include a plurality of concentric electrodes disposed in a housing, a fluid channel defined between the concentric electrodes, and an electrical connector positioned at a distal end of a concentric electrode and electrically connected to the electrode. The electrical connectors may be configured to provide a substantially even current distribution to the concentric electrode and minimize a zone of reduced velocity occurring downstream from the electrical connector. The electrical connector may be configured to cause a temperature of an electrolyte solution to increase by less than about 0.5° C. while transmitting at least 100 W of power.Type: GrantFiled: February 21, 2023Date of Patent: April 16, 2024Assignee: Evoqua Water Technologies LLCInventors: Andrew Green, Li-Shiang Liang, Joshua Griffis, Paul Beddoes
