Sažetak
Due to the high content of organic matter and intensive colouration, even with low concentrations of dye, wastewater from the dye industry and dyehouses cannot be discharged to the recipients without further treatment. In this work, the application of a high voltage pulsed electrical discharge in the aqueous phase has been studied. Experiments were conducted in a batch reactor using water solution of commercial monoazo dye C.I. Direct Orange 39 (DO39). The effects of zeolite and ferrous sulphate in combination with the "corona" electrical discharge were examined. A mathematical model to describe the kinetics of DO39 mineralization in the corona reactor was developed. Ecological parameters of wastewater such as COD, TC, IC, TOC and IC50 measured before and after corona treatment showed that the treated wastewater can be discharged into the environment or reused as process water.
