Abstract

Water and wastewater treatment is essential for ensuring the availability of clean and safe water for different uses. Sono-ozone processes, which combine ultrasound (US) and ozone, have garnered attention for their ability to effectively remove contaminants and enhance water quality. US creates microbubbles in the liquid through acoustic cavitation, and when ozone is added, these microbubbles aid in the transfer of ozone, following the production of reactive species that break down organic pollutants, leading to the removal of contaminants from the aqueous media. As the demand for sustainable and efficient water treatment solutions continues to grow, sono-ozone processes are poised to play a pivotal role in addressing water quality challenges across various industries and environmental remediation efforts. However, the feasibility and efficacy of these new methods require thorough studies to ensure their successful implementation. This book chapter discusses sonication, ozonation, and sono-ozone processes, emphasizing their application for water and wastewater treatment. The advantages, disadvantages, and influencing factors of the sono-ozone process are also highlighted. © 2026 Elsevier Inc. All rights reserved.
