▎ 摘　　要

NOVELTY - The apparatus has a pair of electrodes (10) between which a feed solution passes through to remove the ionic substances from the feed solution through adsorption by electrostatic force. A graphene (22) or a cation exchange resin and an anion exchange resin are mixed together to provide the cation and the anion exchange resins in a flow channel between the pair of electrodes. USE - Capacitive deionization apparatus. ADVANTAGE - The electric resistance in the flow channel is reduced and the size of the flow channels is increased to minimize the fouling effect and promote the water throughput and enhance the deionization efficiency to reduce the CAPEX cost. The need of using an expensive ion exchange membrane to enhance the deionization efficiency is eliminated. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the capacitive deionization apparatus.
