Abstract

The influence of basic discharge parameters on the efficiency of bacterial decontamination in liquids has been studied, The experiments have been carried out with a voltage of 19 kV, a pulse repetition rate of 0.1-10 Hz, and a pulse energy of 3-10 J. The pulses were applied to electrodes located in a water-filled cell. The suspension contained staphilococci or E. Coli with a concentration of 10⁶-10⁸ per ml. At 10 J/ml energy input, the bacterial decontamination efficiency was found to be 100%. Even at low -2.5 J/ml energy density, the efficiency of removing the bacteria was still more than 94%
