Treatment of Distillery Spentwash in Upflow Anaerobic Contact Filter

G. Venkatasamy, S. Aruna

Abstract :

Molasses–based distilleries are one of the most polluting industries generating an average of 8– 15 litres of spent wash per litre of alcohol produced, a huge volume of wastewater is generated. In the present study, an attempt has been made to treat the distillery spentwash by using polyurethane foam as a packing material in the upflow anaerobic contact filter (UACF). The effect of hydraulic retention time (HRT) in treatment efficiency of UACF was evaluated at different initial substrate concentrations ranging from 360mg/l to 10,000 mg/l. The COD removal percentage during the period of investigation was found to be in the range of 69 to 96%.
