| Summary: | Preserving food and improving the quality of drinking water are of paramount importance to the public. Despite the very different objectives of food preservation and drinking water disinfection, these problems have in common the destruction of microorganisms. In this regard, the actual problem, which has been the focus of research in recent years, is the development of new technologies capable of non-thermal treatment of liquid substances and foodstuffs and not using chemical reagents. Hydrodynamic cavitation can be a promising technology for non-thermal treatment of liquid substances, including wastewater and food liquid products. This paper presents the results of our own study of the effect of cavitation on microorganisms under given conditions in a device with a discrete secondary part.
