Synthesis of Calcium Carbonate Nanoparticles and its Application in Grey Water Treatment

Abstract Nanotechnology is one of the emerging technologies with unique functionalities and great potential in removal pollutants from waste water. Nanoparticle mediated water treatment a promising alternative to traditional techniques. Considerable amount grey thrown out household activities on daily basis, which turn lead environmental pollution long run hence results increased fresh consumption. The present study focused synthesis calcium carbonate nanoparticles using homogenisation process for were characterised Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD). synthesised employed batch by varying solution pH, stirring time; speed dosage nanoparticles. pollutant efficiency assessed measuring Chemical Oxygen demand (COD), Total Suspended solids (TDS), dissolved Dissolved oxygen (DO) turbidity. demonstrates that optimum was obtained at pH 8.0, 100 rpm, mixing time 75 minutes 0.7 g maximum reduction COD processing condition 78%. outcome suggests nanoparticle could effectively remove This research line United Nations Sustainable Development Goals (UNSD), clean sanitation. community engagement project will serve society saving produce environment.
