As the reactions of plasma particles produced by pulse discharge in water are complex, the software CEA2 is employed to simulate and compute the content of each species of product in the plasma channel by converting discharge energy into enthalpy. The respective content of OH and H2O2 is measured by chemical methods in the self-developed reaction device. It is found that experimentally-detected concentrations...
This paper presents experiments conducted using a high voltage pulsed spark plasma discharge having the following parameters: peak-to-peak voltage 25 kV, peak-to-peak current 400 A, pulse duration 1.8 mus, frequency 1-50 Hz and energy per pulse 2 J. This study demonstrates that a rather low energy input of 75 J/L of water is required to obtain a one-log reduction in Escherichia coli concentration...
