Adding an electrolyte to increase the ionic strength of the solution produced an enhancement in the ion arrangement by increasing the concentration of charge carriers and decreasing the solution's resistance. As result the system increases the transport rate of charge flowing through the cross section between the electrodes by streamlining the process of EC. As result, lower requirement of electrical potential was observed for higher pollutant removal, as shown in the experiments with salt addition. For these experimental runs, the addition of 0.01MNaCl showed an ECEI value of 360.0 kWh Kg_1 cm_2 achieving 72.5% of COD removal. Increasing NaCl concentration added up to 0.1 M (i.e. one order of magnitude higher) generated an ECEI value of
185.4 kWh Kg_1 cm_2 and achieved 83.9% COD removal. Evidently, the second is more effective on both, energy consumption and removal.
