Original Abstract

Nowadays removal of organic pollutants from water environment is highly required. Besides physical, chemical and expensive biological methods, so-called advanced oxidation processes (AOPs) are developed and applied for propose of water treatment. One possible method suitable for degradation of organic compounds is generation of electrical discharge in the treated medium. Processes initiated by the discharge in water lead to the formation of various reactive species (mainly radicals) that subsequently react with present molecules and cause their decomposition. Also UV radiation and shock waves (in the case of pulsed voltage) are responsible for the molecule destruction. Our work focuses on the diaphragm discharge generated by the DC non-pulsed high voltage in water solutions containing model organic compounds (dyes) and some additives (electrolytes).
