Abstract
In presented article the high-voltage technology for inactivation of drinking water and wasterwater from various microbes and viruses is considered. As a power source and investigated object – high voltage pulsed generator with output tension 100 kV and water mediums (drinking and waste water) with contained microorganisms respectively were used [1, 2]. At influence of high electric fields in water both thermal and electric processes with formation of gas inclusions and plasma channels respectively, generation of high-frequency radiation (infrared, visible, ultraviolet and X-ray) are taken place. Results of experiments and calculations confirm dependence of usefull emitted energy in water from some parameters of electrode system (radius of curvature, bared area of “pin” electrode and inter-electrode distance). In addition, electric processes in water are also depended from medium’s electro conductivity. At tensions less 20 kV only thermal and electrolysis processes in water are taken place. Above 20 kV ionization processes in gas inclusions with formation of conductive leader channels by high temperature and pressure, moving to opposite electrode at subsonic and supersonic speeds are occured. It is depending from voltage amplitude and polarity. Discharge processes are accompanied by shock ionization, photoionization, and in combination of micro and nanopulse effects by formation of high-energy electron beams that cause X-rays. As a result of dissociation of water molecules and atoms under effect of strong electropulsed fields is occurred accumulation of metal ions on membrane, which play the bridge role for penetration of electric fields into cell [3-5]. It can cause explosive processes within the membrane and cause its destruction. With shortening the pulse front is improving penetration of high-frequency pulsed fields directly into the nucleus of biological cell. Microbiological analyses of treated water were shown, that concentrations of available bacteria and viruses are below the maximum allowable.
