Confirmatory test of bacterial cell damage & Preliminary test on actual sewage wastewater. FE-SEM images of E.coli under optimized conditions of (current density = 7.14 mA/cm2, NaCl dose = 0.2 g/L, treatment time = 8 min, flow rate = 40 mL/min). (a) E.coli before EO treatment (b) After EO treatment images of E.coli. The arrows show the bacterial cell damage due to RCS production (c) The graph depicts the bacterial inactivation in actual sewage wastewater at the optimized condition (current density = 7.14 mA/cm2, NaCl dose = 0.2 g/L, treatment time = 8 min, flow rate = 40 mL/min). Here, ~ 92% bacterial inactivation can be seen through EO technology within 8 min of treatment time.
