System and method of water purification and hydrogen peroxide generation by plasma

Abstract

A system for generation of radicals in a liquid (e.g., OH and derivatively H2O2 in water) by a plasma reactor, including a first electrode having a rod shape or a tubular shape; a dielectric tubular housing coaxial with the first electrode and enclosing the first electrode, and having a gap to the first electrode of 0.3-30 mm; a second electrode on an outside of the dielectric tubular housing and coaxial with first electrode with a gap 0.3-30 mm; a high voltage power supply providing voltage oscillations or pulses of 0.5-30 kV and a frequency 1-50 kHz between the first and second electrodes; and a pump or a Venturi injector on an output of the plasma reactor and a chock valve on an input of reactor for generating a low water pressure in the gap between first and second electrodes so as to generate boiling in the gap.
