Comparison of properties of EW produced from TW and UW using different EFR and fixed electrolyte concentration (6% HCl) and current are presented in Table 2. The results showed that increase in EFR results in decreasing of pH, while increase in ACC and ORP for the both water used in this study. Although the ACC increased in the both cases, the use of TW appeared to produce higher ACC than that observed for UW. Similar results were indicated by Pangloli and Hung (2013) that increased hardness of water led to increased available chlorine concentration (ACC), oxidation-reduction potential (ORP), and decreased pH of EW.
