This review reveals the synergy between hydrodynamic cavitation and advanced oxidation processes in enhancing wastewater treatment efficiency.

Hydrodynamic cavitation technology generates high-pressure, high-temperature environments that produce oxidative free radicals.
The coupling of hydrodynamic cavitation with advanced oxidation processes shows significant improvements in treatment efficiency and cost.
A notable example is the HC-photocatalytic system achieving 78.2% tetracycline removal, nearly double the individual methods' efficiencies.
Despite its potential, the technology faces challenges in energy utilization and requires further innovations for large-scale application.

Song et al. (2025) studied this question.
