Green synthesis, characterization and application of calcium carbonate nanoparticles in the effective treatment of grey water for sustainable water management

Abstract

The methodology employed in the preparation of calcium carbonate nanoparticles was precipitation and homogenization process using sodium carbonate and calcium chloride. The synthesized nanoparticles were characterized by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), X-Ray Diffractometer (XRD), Fourier Transform Infrared Spectroscopy (FTIR) ) and zeta potential measurement. The batch treatment of grey water with CaCO 3 nanoparticles was carried out by varying the processing conditions (grey water pH, stirring time, stirring speed, and dosage of CaCO 3 ). The efficiency of the treatment process was measured by analyzing the Chemical Oxygen Demand (COD), Dissolved oxygen (DO), Total dissolved solids (TDS), Total suspended solids (TSS), and Turbidity.Green synthesis, characterization and application of calcium carbonate nanoparticles in the effective treatment of grey water for sustainable water management.
