Increasing environmental pollution and drinking water shortages are a growing socioeconomic problem, in which cavitation technology can contribute to a cleaner and greener approach to wastewater treatment. Cavitation is a physical phenomenon that describes the phase change from liquid to vapour and back at constant temperature. The mechanical, thermal and chemical effects of cavitation can be utilised for various purposes, including to inactivate microorganisms in drinking water and wastewater. It has been proven that cells are subjected to damage in the immediate vicinity of a bubble. Further numerical analysis has identified the formation of microjets as a possible mechanism of bacterial cell damage.
