The application of new technologies and research in water treatment are the ways to minimize the impacts caused to the environment and the improvement of water resources and, consequently, the economic and social of a region. Among the technologies, we highlight the Advanced Oxidative Processes (AOP’s), which are based on the use of highly oxidizing species to promote a more effective degradation of the pollutant to be treated. This work aims to conduct a review of POA’s, which are: Photocatalysis with titanium dioxide (TiO2)/ultraviolet (UV), Photo-Fenton and Hydrogen Peroxide (H2O2)/UV, identifying the most suitable processes according to the pollutant to be treated. AOP’s are presented as an option to degrade organic pollutants that have high chemical stability, due to the inefficiency of common methods of treating effluents that are difficult to degrade. Furthermore, AOP’s appear as a technology where it is more efficient in treating effluents at a low operating cost. Therefore, AOP’s have great potential to be applied in the treatment of various effluents obtained from the solvents used in the production of membranes.
