Effect of operational parameters. (a) The graph shows the effect of different current densities (7.14-11.90 mA/cm2) on % bacterial inactivation at NaCl concentration of 0.2 g/L. (b) The graph depicts the effect of different electrolytes (0.2–0.45 g/L NaCl) on % bacterial inactivation. (c) The graph shows the effect of treatment time on bacterial inactivation.
