Enhancing removal of pollutants from pharmaceutical wastewater using ferrites in Membrane Bioreactor: A promising technology for environmental sustainability

Abstract

Industrial wastewater contains various toxic and hazardous pollutants that require effective treatment to meet environmental regulations. In recent years, silver-doped ferrites have gained attention as promising materials for the treatment of industrial wastewater in membrane bioreactor (MBR). In this abstract, we will discuss the potential of silver-doped nickel ferrite (AgNiFe2O4) and silver-doped potassium ferrite (AgKFe2O4) was synthesized by sol-gel technique for the removal of pollutants from industrial wastewater. AgNiFe2O4 and AgKFe2O4 nanoparticles have been found to be effective for the removal of various pollutants, including heavy metals, organic compounds, and dyes, from industrial wastewater. Several studies have reported the successful application of silver-doped ferrites for the treatment of industrial wastewater. X-ray diffraction (XRD) pattern reveals the single phase cubic spinel structure with space group Fd-3m and Scanning electron microscope (SEM) confirmed the surface morphology of the synthesized nanoferrites. The use of AgNiFe2O4 and AgKFe2O4 has been found to significantly reduce the concentration of pollutants in wastewater, making it suitable for safe discharge into the environment. Furthermore, the regeneration of silver-doped ferrites has been found to be simple and cost-effective, making them an attractive alternative to conventional wastewater treatment methods. In conclusion, silver-doped nickel ferrite and silver-doped potassium ferrite have shown great potential for the treatment of pharmaceutical wastewater in MBR technique and ferrite materials make them promising candidates for future wastewater treatment technologies.
