Exploration of the high speed processes in designing of pulsed electrotechnologies

This article to development of high-frequency electric technologies (micro and nanosecond) for cleaning and disinfection of drinking and waste water from bacteriological pollutants is devoted. Complex explorations of high-speed processes in water medium, optimal electrical parameters of energy source and impact modes (crown and spark discharges) on investigated objects are considered. Empirical formulas for determination of the main discharge characteristics (average breakdown time, emitted energy) and parameters of water gap, at which an effective work regime of high voltage equipment is reached, are given. The possible mechanisms of water breakdown and high speed processes, volt-second diagrams are presented. It is shown, that on spark regime in water medium and positive polarity of potential electrode is achieving the maximum inactivation level of bacteriological cells (10
¹⁰
). It was found, that combination of micro and nanosecond effects on water medium may lead to formation of high-energy electrons, generating shortwave radiation and promoting penetration of nano fields into nucleus, suspending the further reproduction of cells.
