The essence of the undertaken research was to analyze and evaluate the impact significance of cavitation process selected parameters on the course and efficiency of organic compounds degradation in hydrodynamic cavitation conditions in the aqueous environmenton the example of model compounds: anthracene and phenanthrene. As part of the research, the hydrodynamic cavitation reactor equipped with exchangeable cavitation inductor was designed and performed. In laboratory conditions, the effect of changes of chosen process parameters such as the inlet pressure and geometry of cavitation-generating component on the anthracene and phenanthrene degradation degree was examined. In terms of treatment technology, the range values knowledge of these parameters enables the induction of controlled phenomenon of hydrodynamic cavitationin the most efficient conditions. Conducted laboratory tests indicate that theuse of hydrodynamic cavitation is an effective process which allows to reduce the concentrations of anthracene and phenanthrene in model aqueous solutions. The selection of cavitation inductor configuration is a very important aspect while maximizing the technology effects.
