“…Moreira Braga et al [ 130 ] used modified nano-vermiculite in a rotating bed reactor for the catalytic ozonation of sanitary landfill leachate. The rotation of the bed, initial pH, and ozone flow were analyzed through experimental design represented by the central composite design (CCD) and later optimized through the Normal Boundary Intersection (NBI) algorithm.…”

“…El tratamiento de los lixiviados debe alcanzar unos estándares mínimos, generalmente expedidos por la autoridad ambiental para evitar los daños ecológicos y de la salud poblacional [52]. En los países en desarrollo se han implementado los procesos convencionales físicos, biológicos y/o filtración con membrana, sin embargo, muchas veces no es suficiente [53]. Por lo tanto, es requerido aumentar la reducción de la carga contaminate por medio de métodos avanzados, como lo PAOs [20], entre los cuales, procesos basados en ozono ha sido considerados unos de los más prometedores [3].…”

“…1 Conventional treatment techniques such as biological (anaerobic and aerobic methods) and physical/ chemical (flocculation and flotation) processes are not sufficient to fully reduce the environmental hazards associated with leachate. [5][6][7][8] Therefore, novel treatment technologies have been extensively investigated, including advanced oxidation processes (AOPs) and combinations of superoxidants such as H 2 O 2 or O 3 combined with ultrasound (US), electron beam (EB), ultraviolet (UV), catalysts (Fe 2+ ) and photocatalysts (TiO 2 ) to generate hydroxyl radicals (˙OH), [9][10][11][12][13] degrading most of the recalcitrant organic molecules to biodegradable intermediates and even to H 2 O and CO 2 . 14 There are also methods such as membrane filtration (e.g.…”
