  • Publication number: 20220234916
    Abstract: Methods and systems for in situ electrochemical treatment of aqueous solutions used in agricultural systems, community systems and industrial systems. In aspects, is an in situ electrochemical method for the treatment of fertigation water, comprising: flowing the fertigation water through an electrochemical cell comprising at least one anode and at least one complementary cathode while simultaneously adjusting one or more of current density, flow rate and pH, wherein said flowing fertigation water contacts the anode and cathode causing one or more of: degradation of a recalcitrant organic contaminant, mineralization and solubilization of an organic, forming a disinfection agent against a pathogen, and maintaining nutrient levels in said fertigation water; and collecting treated effluent.

  • Patent number: 10995021
    Abstract: 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: Grant
