Industrial organic wastewater effluents affect our ecosystem, especially when discharged without any treatment. Nowadays, advanced oxidation process (AOP) is considered one of the most conventional treatment techniques. It mainly depends on producing hydroxyl radicals (∙OH) in presence of an oxidizing agent and/or bulk or nanoparticles which must have high sorption affinity and photocatalytic activity to speed up the treatment process. In this study, a magnetic iron oxide (Fe3O4) nanoparticle was used along with hydrogen peroxide (H2O2) and sodium persulfate (Na2S2O8) for comparison purposes. This magnetic nanoparticle (MN) has a high surface-area-to-volume ratio and is magnetic in nature which can be recovered by a magnetic field for further cycles of treatment and regeneration once needed. To the best of our knowledge, there is no continuous industrial process for such a treatment. Thus, a bench-scale setup that provides continuous wastewater flow was built which mainly depends on using four stages mechanism and recovering MN using the magnetic field. This study should help in quantifying the efficiency, performance, and give insights regarding its feasibility towards wastewater treatment on an industrial scale. Hence, design and automated controlling parameters, optimal operating conditions, and economical descriptions were addressed in this work.
