Fluidized capacitive deionization device

Abstract

This disclosure provides a fluid capacitive deionization device, comprising a device body, an inlet liquid, and at least one capacitor module. The device body has an outlet and an inlet. The inlet liquid flows through the device body and includes a fluidized electrode. The capacitor module is disposed within the device body and includes a first current collector, a second current collector, and a water-permeable non-conductive layer. A positive voltage is applied to the first current collector. A negative voltage is applied to the second current collector, and a gap exists between the second and first current collectors. The water-permeable non-conductive layer is located between the first and second current collectors. This reduces the possibility of contamination and clogging of the fluid capacitive deionization device.
