Hybrid Electrochemical Desalination System Combined with an Oxidation Process

Here, we report a novel hybrid electrochemical desalination system synchronized with an oxidation process for the first time. As one of the breakthroughs in electrochemical desalination systems, the oxidation process is demonstrated as a strategy to overcome the drawbacks of electrochemical desalination systems associated with the difficulties of anion adsorption/intercalation. This hybrid system consists of a cation-selective battery material in the desalination component, an oxidant generating anode in the oxidation component, and an anion exchange membrane that offers a channel for the diffusion of anions. During the operation, cations are intercalated into the battery material, and reactions occur on the anode to generate reactive chlorine species (e.g., Cl 2, HOCl, and • Cl), and reactive oxygen species (e.g., H 2 O 2, • OH, and O 3 ). Simultaneously, the anions in the desalination …
