Green Synthesized Mixed Oxides (ZnO and MgO) Nanoparticles for Wastewater Treatment over Filtration Technique for Bioremediation Application: A Comparative Study

Abstract

Aim: Rapid urbanization and industrialization have resulted in dye-contaminated wastewater, which has become a global issue. This application's goal is to improve suspended solids removal efficiency while also increasing sand surface area through the addition of functionalized green copper oxide nanoparticles as a novel filtration bed. Materials and Methods: Eco-friendly, naturally-occurring materials are used to make these types of nanoparticles at the macro level. There are two groups, each containing 9 samples  with G power 80% and coincidence interval of 95%. Results and Discussion:Using batch adsorption studies, the adsorption affinity and capability of nanoparticles to remove suspensions from a locally supplied industrial wastewater sample were investigated. An increase in suspension removal efficiency of 66% was found when functionalized sand was combined at a low mass fraction (5 weight %) with mixed oxide nanoparticles (ZnO-MgO). This was followed by a continuous run of the filter bed column with functionalized and non-functionalized sands, P=0.001 . Conclusion: Using in-house generated ZnO-MgO mixed oxide-based nanoparticles, the functionalized sand unexpectedly had a breakthrough time 50 times faster than the unfunctionalized sand. This promising new research will, according to the scientists, help refine current industrial and laboratory wastewater treatment methods.
