This study evaluated the efficiency of catalytic ozonation with magnetite (Fe3O4) in degrading recalcitrant organic compounds leachates from two sanitary landfills Colombia. The optimum treatment conditions were also analyzed by means a response surface design, resulting 6 g O3/h, 2.5 g/L Fe3O4, and pH 9, which resulted COD removal rates 85.3% El Guayabal 75.8% La Madera. Moreover, BOD5/COD ratio increased 0.26 to 0.38 0.23 0.32, respectively, suggesting effluent biodegradability. most efficient ozone consumption (2.7 O3 per gram removed) was obtained under alkaline high catalyst concentration. Magnetite demonstrated structural stability, although its progressively decreased after three cycles use, decreasing 73.6%. These findings validate as an alternative for advanced leachate treatment, potential optimize contaminant industrial effluents strengthen environmental remediation strategies.
