Abstract

This study has been undertaken to investigate and evaluate the Physico-chemical parameters of tannery effluent. Dindigul is known for its Tanneries present in and around the district. Both untreated and treated effluent samples were collected from the discharge sites of industries for the analysis of various physical and chemical parameters. Various Physical and Chemical parameters such as Appearance, Temperature, Turbidity, and Electrical conductivity, Total Dissolved Solids, pH, Alkalinity, Acidity, Total Hardness, Salinity, Dissolved oxygen, Biological Oxygen Demand and concentration of Chromium were also analyzed. All the parameters were almost higher for untreated effluents when compared to the treated effluents. Higher ranges of values recorded also exceed the permissible level. Higher amount of hexavalent chromium was also recorded. From this investigation, it is concluded that untreated effluents were highly polluted and affects the environment when discharged without proper treatment.
