INTRODUCTION The treatment was distillery wastewater is important asepct of sustainable growth of agro economy. The distilleries provides value addition to the sugar industry wastewater. The wastewater contains high amount of organic matter. This organic matter consumes dissolved oxygen(DO). The permissiblem minimum dissolve oxygen is 5 mg/l and desirable is 10 mg/l. The water with low DO smells very bad and not suitable for use. Removal of organic matter is normally done by activated sludge process in conventional plants. Studies have revealed that these plants are not effective and there is need for advanced treatment method for tackling the problem. The present work includes review of some investigations on various advanced methods for COD removal. Also experimental resluts of batch and column experiments for COD removal by using groundnut shell adsorbent are reported in the present paper. 2. LITERATURE REVIEW The chemical oxygen demand and biological oxygen demand are important indicators of the dissolved oxygen content of the wastewater. Various studies have been reported on removal of the organic matter and subsequent effect on dissolved oxygen[1-5]. Various investigations on effect of organic matter on river and resrviors indicate that the orgaic matter with high COD is reaching alarming level in the country. A review on modelling of packed beds for wastewater treatment was presented by Kulkarni [6].Accrding to him, various models like Thomas model, Yoon Nelson model and Modified Dose model are used for describing breakthrough curves. Amale et.al.used wood charcoal as an adsorbent in a fixed bed for removal of organic matter from effluent[8]. They observed decrease in exhaustion time with initial concentration. With increase in bed height, the exhaustion time delayed. Dairy wastewater treatment by anaerobic fixed bed reactors was carried out by Nikolaeva et.al.[8].They used hybrid material composed of waste tyre rubber and zeolite.They observed that increase in the hydraulic retention time(HRT) brought about an improvement in the effluent quality.Kulkarni and Goswami used bagasse flyash as an adsorbent for organic matter removal from wastewater[9]. They carried out investigation in batch and column modes with satisfactory results.Electrocoagulation was used for organic matter removal by Khandegar and Saroh[10].They Abstract: Removal of organic matter is normally done by activated sludge process in conventional plants. Studies have revealed that these plants are not effective and there is need for advanced treatment method for tackling the problem. The present work includes review of some investigations on various advanced methods for COD removal. Also experimental resluts of batch and column experiments for COD removal by using groundnut shell adsorbent are reported in the present paper.The parameters affecting the adsorption were studied and optimum values of these parameters were estimated. For the initial 0.5 to 1.5 grams of adsorbent, comparatively steep drop in concentration is observed. The central part of the curve indicates almost linear drop in COD with increase in adsorbent dosage.At lower pH, the H + ions compete with adsorbate for the sites. At higher pH, there can be formation of complex ions or there can be hydroxides formation and subsequent precipitation also.
