| contents | Design and development of a modified nanobubble-assisted advanced oxidation process (M-AOP) for high-efficiency wastewater treatment. Shakouri, Arash Abdolrazaghi, Manda The increasing prevalence of recalcitrant organic pollutants in wastewater necessitates the development of advanced, highly efficient treatment technologies beyond conventional methods, which often struggle with cost-effectiveness and complete pollutant mineralization. This study aimed to design, assemble, and evaluate a novel Modified Advanced Oxidation Process (M-AOP) that integrates a gas nanobubble injection unit with a multi-component oxidative system to overcome the limitations of standard treatments. The performance of the developed M-AOP was rigorously compared against a normal aeration system (T1) and a conventional AOP system (T2) for the removal of chemical oxygen demand (COD) from real municipal wastewater over a 15-hour treatment period. The M-AOP system (T3) demonstrated superior performance, achieving a COD removal rate of 97.9 ± 0.3%, significantly higher than that of the conventional AOP (70.6 ± 2.1%) and normal aeration (36.1 ± 1.5%). The overall COD reduction in the M-AOP system was 2.4 and 1.3 times greater than in T1 and T2, respectively. Furthermore, the M-AOP exhibited a remarkably high initial removal rate of 85.5% within the first 5 h, indicating a rapid and potent oxidative capability. In conclusion, the integration of nanobubble technology significantly enhanced the efficacy of advanced oxidation processes, enabling near-complete COD removal. The M-AOP system represented a promising and robust solution for treating organic-laden wastewater. Future research will focus on pilot-scale validation, a detailed techno-economic analysis, and the system's efficiency in removing specific micropollutants and pathogens. |
