Description:
Hydrodynamic cavitation has shown considerable application promise in wastewater treatment due to its simple reactor design and capacity in large scale operation. In this paper, different aspects of hydrodynamic cavitation used for wastewater treatment have been reviewed. Theoretical studies, including the basic mechanism of pollutant degradation, the modeling of pressure distribution in cavitation reactor and the bubble dynamics models coupled with chemical reactions, are evaluated. Experimental setups with different cavitation reactors and operation parameters are compared under the desired conditions for degrading specific kinds of pollutants in wastewater. In addition to hydrodynamic cavitation, some synergetic approaches are also reviewed. On basis of this, the effort directions for both theoretical and experimental investigations have been suggested. Overall, such features as the easy large-scale operation, the effective combination with intensified strategies and the potential to deal with the bio-refractory or toxic compounds contribute to the position where hydrodynamic cavitation stands in wastewater treatment field.
