Abstract: Due to such expressive population growth and industrialization in recent years, the generation of wastewater has increased significantly. An efficient treatment of these effluents aiming at an adequate disposal is something challenging, especially due to the variety of existing pollutants. Conventional methodologies generally applied are inefficient for the treatment of recalcitrant compounds, however this issue requires special attention in terms of environmental and public health protection. The use of advanced oxidative processes (AOP), which has been reported for over a century, has been gaining more space and is successfully used, and it is possible to verify the growing number of publications on this topic. Some articles and review works are available in the literature, where very different approaches focused on the various types of POA can be observed. This review article summarizes the basic principles of this treatment technology, highlighting the basic reactions involved along with the main operating parameters. In addition, the results obtained in research on the use of POA for the treatment of polluting substances, especially dyes, were highlighted.
