Abstract

Hydrodynamic cavitation is a promising wastewater treatment.In this paper,the principle of hydrodynamic cavitation was introduced briefly.The effects of various operation and geometric parameters on the cavitation,such as inlet pressure,geometry of constriction,physico-chemical properties of liquid,and so on,have been discussed.Furthermore,there was some analysis about several hydrodynamic cavitation reactors.The hydrodynamic cavitation reactors have some virtues: simple design,convenient control and easy transfer from the laboratory scale into commercial scale.Moreover,comprehensive reviews on the applications and research advances in wastewater treatment have been given.The investigation demonstrated that hydrodynamic cavitation was a long term potential water treatment technique.Finally,several problems encountered during the period of the technique maturity and the developmental trends are expounded.
