T1 Effects of H2O2 and Low pH Produced by Gliding Arc Discharge on the Inactivation of Escherichia Coli in Water JF Plasma Medicine JO PMED YR 2011 FD 2013-02-11 VO 1 IS 3-4 SP 295 OP 307 K1 hydrogen peroxide K1 gliding arc discharge K1 E. coli K1 bacterial inactivation in water K1 pH variation AB The efficacy of gliding arc (GA) discharge for the generation of hydrogen peroxide (H2O2) and water with a low pH was studied because H2O2 combined with low-pH environment is known as a strong oxidizer that can be used for the bacterial inactivation. The ability of the GA discharge to inactivate Escherichia coli in water was tested experimentally, and the inactivation was found to increase with the plasma treatment time and rate of water injection flow to the GA discharge system. The best result showed a 2-log reduction of the number of colony-forming units of E. coli from 104 to 102 at a water injection flow rate of 180 mL/min. Furthermore, pH in the plasma-treated water was decreased from 6.0 to 3.55 after 25 min of treatment.
