Abstract

SR-AOP (sulfate radical advanced oxidation process) is a novel water treatment method able to eliminate refractory organic pollutants. Hydrodynamic cavitation (HC) is a novel green technology, that can effectively produce strong oxidizing sulfate radicals. This paper presents a comprehensive review of the research advancements in these fields and a critical discussion of the principal factors influencing HC-enhanced SR-AOP and the mechanisms of synergistic degradation. Furthermore, some insights into the industrial application of HC/PS are also provided. Current research shows that this technology is feasible at the laboratory stage, but its application on larger scales requires further understanding and exploration. In this review, some attention is also paid to the design of the hydrodynamic cavitation reactor and the related operating parameters.
