Introduction
Sugar industries are one of the largest agro based industry. The industry utilized around 1500–2000 dm3 of water and generated about 1000 dm3 of wastewater per ton of can processing [1]. Wastewater mainly comes from floor washing, condensation, leakage, spillage of sugarcane from valve and pipelines, syrup and molasses in different sections [2]. The composition generated from SI has high content of organic material because of the presence of sugar and organic material in the beet or cane. SI produced untreated effluent of BOD 1700–6600 mg/dm3, COD 2300–8000 mg/dm3 and total suspended solid 5000 mg/dm3[3]. The wastewater may also contain pesticides and herbicides and pathogens from contaminated material or produced processes. A part from these the effluent generated odour to surrounding area up to several meters. Discharge of the effluent without proper treatment can create serious environment problem, therefore, it is need to treat properly before to discharge in water receiving body. Conventional treatment methods used to treat SIWW include preliminary filtration of suspended solids, flow and load equalization, biological treatment and sedimentation for sludge removal. Aerated ponds are also considering for the treatment of SIWW but high oxygen consumption limits the process. Some process have been reported to treat SIWW includes electrochemical oxidation [1] and [4], membrane separation [5] and biochemical oxidation [6]. As per open literature available, no works have been reported in electrochemical treatment (ECT) of real SIWW.
