Abstract
The ability of a GA discharge to produce hydrogen peroxide (H2O2), a potent oxidizer, was investigated to evaluate the optimum operational condition of the GA discharge for bacterial inactivation. The concentration of H2O2 was measured in liquid phase, and its effective residual time was evaluated in a 200-W GA discharge system at different air and water flow rates. The concentration of H2O2 was the highest at the least water flow rate. In addition, a 5-log reduction in the colony forming unit (cfu) number of E. coli was observed at a H2O2 concentration of 100 mg/L in water.
