A Device for Electrical-Discharge Treatment of Water for Biological Investigations

A high-voltage device for generating low-temperature plasma in water that is saturated with air bubbles is considered. It contains a discharge chamber and a generator of voltage pulses with an amplitude of ~30 kV and a rise time of ~5 μs, which is able to form spark discharges with an energy of ~1 J at a frequency of several hundred hertz. The electric circuit of the generator of discharges in water, which provides its high efficiency, and the design of the discharge chamber, which allows formation of parallel air flows through the water-filled interelectrode gap, are described. The results of studies of electric-discharge processes and the results of the chemical analysis of water samples that are enriched with products of plasmochemical reactions are presented. The possibility of the accelerated development of plants that are irrigated with plasma-treated water is shown.
