Disinfectant treatment of liquids with high specific electrical conductivity by high-voltage nanosecond pulses with a subnanosecond front

Purpose. The purpose of the work is to determine, using computer modelling, energy-efficient modes of disinfecting treatment of water-containing liquids with high specific electrical conductivity using high voltage nanosecond pulses with a subnanosecond front including pulsed discharges in gas bubbles. Methods. We considered methods of obtaining high-voltage nanosecond pulses with sub-nanosecond fronts. To achieve this goal, we used computer simulation using Micro-Cap 12. We also used analytical and empirical formulas for calculating the electric field strength, inductive and resistive phases of energy switching from a capacitive source to resistive-inductive loads. We have applied the method of comparing calculated and experimental results. Results. Energy-efficient modes of disinfecting treatment of water-containing liquids with high specific electrical conductivity using nanosecond discharges with a subnanosecond front in gas bubbles are such modes when the active resistance of the treated liquid is 10–40 W. In this case, the lumped inductance of the discharge circuit during liquid treatment does not exceed 2 nH, the capacitance of the layer of the treated liquid is 3.6–14 pF wi
