  • Water synchronic electrodenitrification process
    Patent number: 10364168
    Abstract: The present invention relates to a water purification process carried out in an electrochemical cell in which the content of nitrate ions of an aqueous solution is reduced providing a resulting aqueous solution having a concentration of nitrate concentration lower than 100 ppm, an ammonium concentration lower than 50 ppm and a combined chlorine concentration lower than 2 ppm. The invention also provides a method for designing an electrochemical cell suitable for carrying out said water purification process.
    Type: Grant
    Filed: April 29, 2016
    Date of Patent: July 30, 2019
    Assignee: Hydrokemós, S.L.
    Inventors: Ruth Canicio Bardolet, Olga Onuki Esteban, José Alfonso Canicio Chimeno
