Recent research conducted by researchers at University of SA has demonstrated that capacitive deionisation (CDI) has potential as a desalination process technology. It potentially offers several advantages over Reverse Osmosis (RO) and Electrodialysis Reversal (EDR) processes.  It potential advantages include reduced specific energy, simple operation and low maintenance costs when compared with the incumbent desalting processes. The next step is to pilot CDI in a small remote community currently supplied with brackish water.  Such applications are a process technology ‘sweet spot’ for  CDI.
