This study was performed to investigate the characterization, water quality index, correlation, linear regression analysis and assessment of irrigation quality of leather processing industrial effluent discharged from the industry located at west of Madurai near Dindigul, Tamilnadu, India. Further the treatment study by electrocoagulation was carried out with and without adsorbents viz., Commercial Activated Carbon (CAC), Multi Walled Carbon Nanotubes (MWCNTs) and Graphene (GR). Most of the water quality parameters (WQPs) of effluent were found to be higher than the limit prescribed by Bureau of Indian Standards (BIS) for the discharge of industrial effluent. The decrease in values of Total Dissolved Solids (TDS), both anions and cations were higher in the case of EC with GR and MWCNTs than CAC.
