Capacitive deionisation (CDI) is a water desalination and purification method based on the electric double layer: when a low voltage is applied to the electrodes, cations and anions migrate to the opposite electrodes and are held at the surface, desalting the water (Porada et al., Prog. Mater. Sci. 2013).
Side plates are PMMA and the inner body PEEK; the anode–cathode gap is below 3 mm. The graphite option adds current-collector plates of imported ultra-pure isostatic graphite with serpentine channels.

Dimensions, channel sizes and volume can be customised on request; please state special requirements in your quotation request.
