  • Systems and methods of flexible electrochemical stripping to recover alkaline ammonia and acidic ammonium from wastewaters
    Patent number: 12709560
    Abstract: Most nitrogen recovery techniques recover acidic ammonium fertilizers, and few enable alkaline ammonia recovery. Many embodiments provide multi-chamber electrochemical stripping reactors to recover alkaline ammonia and acidic ammonium from wastewater. The reactor combines electrodialysis and membrane stripping. The acidic and alkaline product portfolio for wastewater-derived ammonia expand implementation opportunities for nitrogen recovery.
    Type: Grant
    Filed: August 16, 2021
    Date of Patent: August 18, 2026
    Assignee: The Board of Trustees of the Leland Stanford Junior University
    Inventors: William A. Tarpeh, Anna Kogler, Brandon D. Clark, Matthew Junjie Liu, William Chow
