“…Hydroxyl radicals are generated when ultrasound waves are transmitted through an aqueous solution (Reaction (5) ) [47] . However, in the concentrated sulfuric acid system with low water content (<2 wt%), very few hydroxyl radicals are formed from water cavitation bubbles [48] . In addition, cavitation is difficult to achieve in highly viscous liquids using the US alone process [49] , [50] .…”

“…(vii) O 3 is swiftly converted into oxygen and disappears after use (Sardana et al, 2019). For wastewater treatment, O 3 and bio-filtration may offer the following advantages: (i) reduction of COD with low or tailored O 3 doses and minimal operational costs; (ii) the oxygen used in activated sludge tank off-gas reduces operating expenses; (iii) due to the multiline input system's architecture, it consumes energy and oxygen (Wang et al, 2021).…”

Over 70% of the planet's surface is covered by water. A universal solvent, water can dissolve a wide variety of compounds. The majority of water contamination is caused by human activity. Increasing water use and pollution are to blame for the current shortage of fresh water supplies. Population expansion, agricultural runoff, and municipal wastewater are the primary sources of pollution in the river. To conduct the study, the logical chain was developed. For the review, open sources of scientific information were used. The focus was on publications from the last 10 years and at the same time; earlier works were taken into accounts that have useful information for this study, which were identified in the list of references when studying recent sources. The number of sources published earlier than 10 years ago does not exceed 7% of the total number of references. The present study aims to determine the optimum conditions for best removal of contaminants as the review focuses on advancement in Ozonation/AOP technology, different type of methods used for drugs removal and different operating condition. Various modern treatment procedures make extensive use of drinking water treatment plants. Water shortages in countries can be alleviated by implementing some of the recommendations made in the research. More catchment areas need to be developed; strict management policies and guidelines should be implemented. Ozonation can also more effectively remove certain personal care products (PPCPs) from the skin. Recycled water can be disinfected using ozonation, which breaks down ozone in water. When ozone is used in this way, it is an effective parasiticide, germicide, and virucidal agent. It can also remove the chroma compounds, smells, infections, and many micro-pollutants simultaneously. Ozone-based AOP should be studied in the future to see whether it is cost-effective and to see if it consumes more energy than other traditional treatment methods.

“…The ozone oxidation process has been widely studied by researchers in the field of water treatment [84][85][86], but it is limited by ozone mass transfer and oxidation selectivity in practical applications. Therefore, many researchers have focused on using microbubble processes to enhance the mass transfer efficiency and utilization of ozone [87][88][89]. Hydroxyl radicals have a strong oxidation ability and can quickly react with electronic sites that are rich in organic matter in water, trigger complex free radical chain reactions and degrade most organic matter into H 2 O, CO 2 and inorganic salts.…”

Ozone micro/nanobubbles with catalytic processes are widely used in the treatment of refractory organic wastewater. Micro/nanobubble technology overcomes the limitations of ozone mass transfer and ozone utilization in the application of ozone oxidation, and effectively improves the oxidation efficiency of ozone. The presence of micro/nanobubbles keeps the catalyst particles in a dynamic discrete state, which effectively increases the contact frequency between the catalyst and refractory organic matter and greatly improves the mineralization efficiency of refractory organic matter. This paper expounds on the characteristics and advantages of micro/nanobubble technology and summarizes the synergistic mechanism of microbubble nanoparticles and the mechanism of catalyst ozone micro/nanobubble systems in the treatment of refractory organics. An interaction mechanism of nanoparticles and ozone microbubbles is suggested, and the proposed theories on ozone microbubble systems are discussed with suggestions for future studies on systems of nanoparticles and ozone microbubbles.
