Catalytic ozone oxidation, which is characterized by strong oxidizing properties and environmental friendliness, has been widely used in organic wastewater treatments. However, problems such as a low pollutant removal efficiency unstable operation during the catalytic treatment process for remain. To address these disadvantages, this study, efficacy of oxidation on coal chemical reverse osmosis concentrate was investigated. The basic water quality indicators were analyzed. effects initial concentration, pH, catalyst concentration COD rate from explored. Water before after studied using spectroscopic analysis methods. RO demonstrated large fluctuations, ozonation removed most pollutants treated wastewater. A possible deactivation mechanism also proposed. This study provides theoretical reference technical support long-term, efficient, stable practical engineering applications.

Electrocoagulation (EC) has been a well-known technology for wastewater treatment over the past centuries, owing to its straightforward equipment requirements and highly effective contaminant removal efficiency. This literature review emphasizes influence of several input variables in EC system such as electrode materials, applied current, pH, supporting electrolyte, inner-electrode distance on effluent efficiency energy consumption. Besides that, depending intrinsic properties effluents, is recommended hybridize with other methods physical-, biological-, chemical-, electrochemical order enhance performance reduce Subsequently, comprehensive analysis presented, including power consumption, evaluation synergistic effect multiple using statistical methods. Finally, this discusses future perspectives environmentally friendly utilization post-EC treated sludges, development renewable energy-driven systems, challenges management by artificial intelligence.

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.
