BECERRA-MORENO, Dorance et al. Advanced Oxidation Processes Based on Ozone as a Treatment Alternative for. Ciencia en Desarrollo [online]. 2021, vol.12, n.2, pp.95-108.  Epub Jan 30, 2022. ISSN 0121-7488.  https://doi.org/10.19053/01217488.v12.n2.2021.12503.

Ozone-based processes are part of the Advanced Oxidation Processes that have been applied on leachates from landfills. The highly toxic characteristics of landfill leachates can be reduced by ozone-based processes, which have been shown to achieve high removals of pollutants, especially recalcitrant organic compounds. In this review, recent information is compiled (2015 to 2021) regarding ozone-based processes, where the efficacy as a treatment has been studied, the optimal conditions are analyzed according to the type of leachate and the treatment method to be used. The implementation trend is identified as pre-treatment and post-treatment coupled with conventional processes.

Keywords : landfill leachate; ozone; AOPs; treatment.
