N2 - The worldwide demands for potable water are continuously increasing due to population growth, global warming, and contamination of fresh-water sources. When dealing with Brackish Water, (BW) Capacitive Deionization (CDI) is a water treatment process that holds the promise of obtaining potable water by high energy efficiency and low expenses. The technology is based on polarizing high surface area electrodes under saline water (electrolyte) by a constant potential; in which an electrical double layer forms and adsorption of the solution ions is obtained. This paper reviews CDI challenges that have been found, analyzed and dealt with by using electrochemical techniques in order to analyze new CDI advantages and enhance the charge efficiency of the regular CDI cell.
