Recently, advanced oxidation processes (AOPs) have found world-wide applications for water treatment and environmental remediation and control of air toxics. Sonolysis alone or in combination with other AOPs such as persulfate and other homogeneous and heterogeneous advanced oxidative species are of particular interests in the research community. AOPs have promise to destroy many emerging organic contaminants in water, soil/sediments and air, and are being considered in potable water treatment, wastewater treatment, site remediation, and industrial applications. Numerous aqueous emerging organic micropollutants such as perfluroalkyl acids (PFAAs), pharmaceuticals, endocrine disrupting chemicals (hormones, steroids, antibiotics, etc.), personal care products, disinfection by-products, and noxious air pollutants have been studied. Two things are needed for any technology to be suitable for use in practice: 1. Technical feasibility and 2. Economic feasibility. This paper will provide a state-of-the-art and unified fundamental chemistry and reaction kinetics involved in AOPs, and techniques to estimate energy needs and cost. It will evaluate the performance and economics of sonolysis alone or in combination with other AOPs, and compare results with conventional technologies. It is intended to advance our fundamental understanding, outline directions for the developments of innovative technologies for water purification, and facilitate the move beyond lab-scale to practical and commercial applications.
