“…Cavities with lower initial size will grow to a larger extent and give rise to more violent collapse 65. Hence, decreasing the initial radius will promote the pressure pulse caused by the bubble collapse and enhance the overall effect of hydrodynamic cavitation 13, 66.…”

Hydrodynamic cavitation is a promising application in wastewater treatment due to its simple reactor design and capacity in large‐scale operation. Theoretical studies including the basic mechanism of pollutant degradation, modeling of pressure distribution in the cavitation reactor, and bubble dynamics models coupled with chemical reactions are evaluated. Experimental setups with different cavitation reactors and operation parameters are compared for degrading specific kinds of pollutants. The effort directions for both theoretical and experimental investigations are suggested on the basis of the reviewed contents. Easy large‐scale operation, effective combination with intensified strategies, and capability to deal with biorefractory or toxic compounds contribute to the great potential of hydrodynamic cavitation.

The Integrated Environmental Technology Series addresses key themes and issues in the field of environmental technology from a multidisciplinary and integrated perspective.An integrated approach is potentially the most viable solution to the major pollution issues that face the globe in the 21st century.World experts are brought together to contribute to each volume, presenting a comprehensive blend of fundamental principles and applied technologies for each topic. Current practices and the state-of-the-art are reviewed, new developments in analytics, science and biotechnology are presented and, crucially, the theme of each volume is presented in relation to adjacent scientific, social and economic fields to provide solutions from a truly integrated perspective.The Integrated Environmental Technology Series will form an invaluable and definitive resource in this rapidly evolving discipline.

“…High-frequency operation (in the range of a few hundred kilohertz to the megahertz range) is recommended when chemical effects are principally required, such as for the degradation of various compounds in wastewater treatment and chemical synthesis. Multiple-frequency operation (combination of the same or different frequencies) also has been reported (Prabhu et al, 2004;Servant et al, 2003) to enhance overall cavitational activity and generating intensities suitable for chemical processing applications at higher energy efficiencies. More important, multiple frequency operations allow the use of lower frequency irradiations (e.g., a combination of 20, 30, and 50 kHz, as demonstrated in the work of Gogate et al, 2003a) even for chemical processing applications, avoiding the common disadvantages associated with higher frequency irradiations.…”
