Development Of Micro And Nanotechnologies In Treatment Of Water Mediums
This article is dedicated to the 100th anniversary of the first water main pipeline in Azerbaijan (“Schollar-Baku”), which will be celebrated in March 2017. The article studies the effect of impact of the strong electric pulsed fields on water mediums (drinking and waste water) for decontamination from containing pathogens (bacteria E-coli, viruses and spores) at “pin-plane” and “pin-pin” electrode systems. Are considered crown and spark regimes of impact on explored objects, thermal and electrical breakdown of water mediums under the influence of micro and nanosecond high voltage pulses. It is shown, that the high-frequency pulse effects on treated medium takes a whole range of physical processes, such as pulsed electrolysis, mechanical compression waves, the formation of ozone, atomic oxygen, ultraviolet radiation, thermal ionization and etc., all of which adversely effect on activity of microorganisms. By Volt-second characteristics Is detected the minimum value of pulsed voltage amplitude, at which is occurred transition from thermal to electric breakdown of water medium. Is shown the maximum inactivation level of microorganisms (~106) in spark discharge mode on positive polarity of “pin” electrode.
