Abstract
The present invention relates to a single module, flow-electrode apparatus for continuous water desalination, ion separation and selective ion removal and concentration by capacitive deionization, comprising: a first current collector (), a first compartment (') for a flow electrode, a first ion exchange membrane (AEM, CEM), a first liquid-permeable channel () next to the first ion exchange membrane (AEM, CEM), a second ion exchange membrane (CEM, AEM) with a fixed charge opposite to that of the first ion exchange membrane (AEM, CEM) next to the first liquid-permeable channel (), a second liquid-permeable channel () next to the second ion exchange membrane (CEM, AEM), a third ion exchange membrane (AEM, CEM) having the same fixed charge as the first ion exchange membrane (AEM, CEM) next to the second liquid-permeable channel (), a second compartment (′) for a flow electrode, and a second current collector (), wherein a fluid () containing suspended conductive particles or a mixture of conductive and non-conductive particles or particles made of a mixture of conductive and non-conductive materials () is provided in the first and second compartments (′), acting as the flow electrode, as well as a corresponding method.
