Abstract
The design and construction of a system consisting of a dielectric barrier cell and the electronic instrumentation intended to generate pulsed discharges at atmospheric pressure in water is showed in this paper. Also, the experimental results from the developed advanced oxidation processes (AOPs) are presented. Demineralised water with a conductivity of 5 μS/cm was used in all tests and a non-thermal plasma is produced between two concentric electrodes in a coaxial configuration by applying high voltage pulses which amplitude can be adjusted from 0 to 30 kV. The propagation of the streamers was characterized by means of the obtained waveforms of voltage and current. The concentration of the ozone generated by the discharges was monitored allowing, in this way, to carry out an analysis of the AOPs, and optic spectroscopy was used to study the discharge parameters involved in such a process.
