摘要

Existing conventional wastewater treatment methods need a new approach for treating complex next generation pollutants such as micropollutants, pharmaceuticals pollutants, biological pollutants, particulate matter, ozone, lead, sulphur dioxide and many others. Moreover, conventional methods of wastewater treatment such as adsorption, photolysis and many others are not feasible on a large scale. Different cavitation technologies alone and coupled with other advanced oxidation processes (AOPs) are used for treatment of waste water from different sources. The present paper focuses primarily on the review of papers relating to industrial wastewater using ultrasonic and hydrodynamic cavitation for organic and inorganic pollutants. A critical study of the designs of several hydrodynamic cavitation reactors (HCRs) that have been utilised to treat industrial effluents has been presented in this paper. There has also been a discussion of the effects of operational parameters such as dilution, intake pressure, ultrasonic power, pH, and operating temperature. Application of cavitation technologies have been discussed with respect to different sources, cavitation technology used combined with other technology and their impact on its property in terms of Chemical oxygen demand (COD) and Biochemical oxygen demand (BOD) reduction. An analysis has been conducted on economic aspects for the treatment of industrial wastewater.
