This paper presents the performance of Upflow Anaerobic Sludge Blanket (UASB) Reactor in treating sugar
industry effluent. The physico-chemical profile of effluent from sugar mill was determined. The parameters measured are
temperature (40°C), colour, pH (7.5), BOD (83 mg/l), COD (321 mg/l), D.O (2.83 mg/l), total dissolved solids (2679.3
mg/l), total suspended solids (301.7 mg/l), total solids (2981 mg/l), chloride (211 mg/l), sulphate (649 mg/l) and oil &
grease (14 mg/l). According to the permissible level suggested by Bureau of Indian Standards, almost all the water
quality parameters in the sugar effluents have been found to be very high and well above the permissible limits. This
study revealed that the effluent discharged from the sugar industry is highly polluted and exceeds the prescribed limits
for irrigation and public use.
