: Effluent originating from sugar industry containing organic contaminants leads to extensive soil and water pollution. From environmental and aesthetic point of view, removal of pollutants containing organic contaminants from effluent is very important. Due to the organics loads, the treatment of removal efficiency is rather challenging by conventional methods. Therefore, adsorption process is found to be the most effective method. Numerous approaches have been studied for the development of low–cost adsorbents. To overcome this burning issue some adsorption methods were utilized. During present study, powdered activated carbon (PAC) with specific surface area 0.5602352m2.gm–1 and particle size 44μm and granular activated carbon (GAC) with specific surface area 0.001050m2.gm–1 and particle size 1.08mm were used for removal of biochemical oxygen demand and chemical oxygen demand (BOD and COD) from combined waste water of sugar industry. Present study is emphasizing on temperature parameter. The change in temperature changes the equilibrium capacity of the adsorbent for a particular adsorbate; this study leads us to the conclusion that PAC removes 61.009% of COD and 97.97% of BOD at 298K whereas GAC removes 66.04% of COD and 60% of BOD at 298K. With increase in temperature, considerable decrease in COD and BOD for both the adsorbents was observed.
