The apparatus allows deposition relatively high applied power into the discharge (order of kW) and treatment of relatively large volume of liquid (order of L/min). The apparatus is operated at the quasi-pulse regime with self-terminating discharge pulses (with repetition rate of 15-20 Hz) generated upon formation of vapour bubble inside the diaphragm (capillary) and its subsequent breakdown. The effects of input power, solution conductivity and method of liquid flowing through the reactor on the plasmachemical yield of H2O2 production and degradation of phenol have been determined. Biocidal effects of the apparatus were evaluated on inactivation of bacteria E. coli and E. faecalis and algae Planktothrix sp.
