Water is essential to human health, economic growth, and environmentally sustainable development. Treating sugar industry effluent is one of the important tasks to save the nearby surrounding and recover the fresh water for industrial application. The goal of research work is to treat the sugar industry wastewater by metal catalyst using catalytic thermal treatment. The results show treatment with copper oxide 84.2% chemical oxygen demand and 89.6% color removal at 5 kg/m(3) catalysis mass loading, optimum pH5, operating temperature 85 degrees C and treatment time 9 h can be archives. The settling rate for 6 kg/m3 mass loading has shown 55% clear liquid and 45% solid interface at 140 min of study. The cake resistance was 2.17 x 10(13) (m/kg) and filter medium resistance 2.71 x 10(9) m(-1) for 5 kg/m(3) mass loading of copper oxide. The sludge obtained after thermolysis has high heating value and can be used as a fuel. (C) 2017 Elsevier Inc. All rights reserved.
