Improper management of wastewater in the textile industry poses a serious environmental issue. Wastewater contaminated with dyes is harmful to the environment, threatens human health, and pollutes aquatic ecosystems as well as drinking water sources. In the search for new wastewater treatment technologies, both hydrodynamic cavitation and non-thermal plasma have shown considerable potential. Combining these two technologies is expected to generate synergistic effects, which is why this approach has become the subject of intensive research in recent years. This master’s thesis focuses on the optimization of operating conditions in a device that integrates both technologies (hydrodynamic cavitation and plasma) with the aim of improving the degradation of organic pollutants. As a model organic compound, the azo dye Reactive Red 120 was selected. In the first stage, calibration curves were established to determine the concentrations of hydrogen peroxide and Reactive Red 120. Subsequently, the formation of hydrogen peroxide during device operation in tap and distilled water was investigated, and the decolourization efficiency of Reactive Red 120 in distilled water under different operating conditions and dye concentrations was compared. The results show that adjusting the operating parameters of the device can influence the degree of dye decolorization.
