Innovative Solutions For Municipal Wastewater: Electrocoagulation And Nano-Membrane Filtration Technologies

Abstract

The extensive use of water in agriculture stresses the ecosystem and increases concerns about a potential water catastrophe in the future. One example of a sustainable approach is using wastewater for irrigation. New contaminants, however, are dangerous to the environment and public health because they can't be removed with standard treatment techniques. Energy-efficient physicochemical processes, such as electrocoagulation-electroflotation and nanofiltration, have the potential to reduce water pollution and expand the availability of clean water. In order to eliminate pollutants, enhance water quality, and support sustainable resource management, this study looks at the novel municipal wastewater treatment methods of electrocoagulation (EC) and nano-membrane filtration (NF). This year-long project aims to implement sustainable wastewater treatment methods at a hospital. The process entails gathering wastewater, filtering out solids, and treating the wastewater with an EC-NF system. The measurement of treatment methods' efficiency is done using anion/cation analysis, pH, BOD, COD, and TDS. This research aims to promote ecologically friendly wastewater treatment systems to improve water quality and save resources. The study assessed EC performance. EC showed high correlations and R values [1]for COD (97.181% removal), BOD (97.4% to 88% at 25°C, 88.5% to 86% at 37°C), NH₃, TSS, and turbidity reduction, indicating efficient pollutant removal. TDS and permeate flux were minimally affected. Hydraulic Retention Time modestly improved COD elimination with low p-value. Pressure (6 bar, R = 0.992) positively influenced COD removal, while Temperature (31°C, R = -0.183) negatively affected efficiency. Further investigation is needed for the relationship between pressure and BOD removal. This study shows that NF removes pollutants from home sewage effectively. Operational parameter optimization enhanced wastewater treatment removal rates, proving its practicality and importance.
