Fig. 4
The 3D surface graph of percentage inactivation. (a) The 3D graph shows the effect of different flow rates (40-200 mL/min) on % bacterial inactivation at varying current density range of (7.14-11.90 mA/cm2) at minimum NaCl concentration of 0.2 g/L. (b) The graph shows the effect of different flow rates (40-200 mL/min) on % bacterial inactivation at varying NaCl concentration (0.2–0.45 g/L) at the lowest current density of 7.14 mA/cm2.
