System for treating wastewater using electrochemistry

Abstract

Systems and methods for treating wastewater using electrochemistry are disclosed. This disclosure relates to a wastewater treatment system comprising a cathode chamber, wherein a cathode is disposed in the cathode chamber, an anode chamber, wherein an anode is disposed in the anode chamber, and wherein a cation exchange membrane is disposed between the anode chamber and cathode chamber and allows the passage of ammonium from the anode chamber into the cathode chamber. A wastewater stream may be in fluid communication with the cathode chamber. Wastewater from the anode chamber may be passed through a centrifuge or filter. A phosphorous recovery tank may be in fluid communication with the anode chamber. The cathode may accelerate the rate of passage of ammonia through a gas-permeable membrane into an acid-stripping solution contained in a stripping tank. A salt solution may be added to the cathode chamber.
