Abstract
Biodegradation offers an eco-friendly option for disposal of waste coming from different breweries and wineries. By using distillery waste as resource material, energy is derived in the form of biogas containing high percentage of methane. The present study deals with the kinetics of anaerobic treatment of distillery wastewater with varying organic load ranging from 8.07g COD/l⢠d to 22.94g COD/l⢠d for a duration of approximately 500 days. The mathematical models such as Monod, Grauâs second order, modified Stover- Kincannon model and First order kinetic models were applied to determine the substrate removal kinetics of anaerobic UASB reactor. Kinetic parameters were determined through linear regression using experimental data. The Grauâs second order substrate removal rate constant (k2) was found as 1.95 per day. By applying modified Stover-Kincannon model, the maximum removal rate constant (Umax) and saturation value constant (KB) were 5 g/ l⢠d and 19.61 g/l⢠d respectively. The outcome of this study will help in simulation of anaerobic model to usable methane and good effluent quality during the treatment of industrial wastewater.
