The discharges in water were intensively studied recently due to their potential application in water and food industry. Several processes are induced in the solution by the discharges. These processes include generation of UV radiation, free radicals, shockwave; pulse electric field (PEF) takes place too. Some of these effects were studied separately to better understanding the complex operation of discharges. The work is focused on the effects of PEF in aqueous solutions only. PEF treatment is non-thermal, chemical-free process affecting microbes. The water solutions or liquid food are treated by high voltage pulses in flow cell that enables to exceed certain threshold value of electric field. New experimental device for PEF treatment is described in this work. It provides PEF pulses of rectangular shape of the amplitude up to 70 kV/cm, 2μs FWHM and pulse repetition rate of 50 Hz. PEF treatment of water solution containing microbial culture is presented.
