Sugarcane is valuable crop of India and has a major role in foreign exchange. The aim of research work is to investigate the reduction of chemical oxygen demand and color from sugarcane industry effluent by thermolysis and coagulation method. The complete study was done in batch mode to determine the effect of operating parameters. The result shows maximum 73% of chemical oxygen demand and 76% color removal with copper oxide catalyst at 5 kg/m³ massloading, 85 °C reacting temperature, 9 h treatment time and pH 8. Combined study showed 97.6% chemical oxygen demand and 99.9% color removal at pH 6.5 and mass loading 8 mM with copper sulfate salt. The settling and filtration was found to be good at 65 °C and 75 °C with copper oxide treated sugar industry wastewater.
