Sterilization of Underwater Bacteria by Ozone Bubble Pulsed Discharge

Electric discharge is going to be applied bactericidal inactivation in water without chemical dosing. In this article, the sterilization experiments of simulated reused from an industrial washing machine were conducted by three different treatment methods: 1) air bubble pulsed (ABPD); 2) O3 alone; and 3) ozone (OBPD). The results showed that: highest effect was obtained OBPD since number sterilized bacteria larger than sum ABPD that alone treatment, synergistic exists. order clarify decisive factor we measured dissolved concentration, pH, ${\mathrm {NO}}_{\mathbf {3}}^{\mathbf {-}}$ emission intensities O radical, H2O2 concentration. As a result, concentrations less 0.02 mg/L all conditions, there no difference pH between radical generated concentration (5.82 mg/L) with (100 ppm) treatment. From these results, conclude increase AOP O3/H2O2 are
