In many developing countries, especially in Asia and South America, Sugarcane industry is one of the most prevalent agricultural industries. As a consequence, sugar cane industry has significant wastewater production. Rapid urbanization and industrialization in the developing countries like India are facing severe problems in collection, treatment and disposal of effluents. Un managed sugar mill effluent is found to have high contents of COD, BOD, TSS, TDS, and low contents of DO resulting in large scale contamination of land, water and air. This leads to serious public health problems and environmental degradation. Unfortunately, due to lack of knowledge, financial support and sometimes unwillingness to spend on treatment of wastewater, most of sugar industries in developing countries discharge wastewater without adequate treatment. For treating the biodegradable impurities, the natural choice is biological treatment, which could either be aerobic or anaerobic. But anaerobic digestion is an attractive waste treatment practice in which both pollution control and energy recovery can be achieved. Sugar industry wastewater was treated in a UASB ( Up flow Anaerobic Sludge Blanket). In this review, the sugar industry wastewater generation sources, characteristics, recent advancements in the aerobic, anaerobic, and physico-chemical treatment technologies, Up flow Anaerobic Sludge Blanket Reactor technology and the areas needing further research have been explored.
