Abstract

Kinetic studies were carried out for anaerobic digestion of distillery spent wash considering growth kinetic models due to Monod and Contois. The kinetic parameters were predicted with the help of previously published experimental data for anaerobically treated distillery spent wash. The digester was operated at seven different values of loading rates ranging between 0.954 to 2.459 gCOD/L/day. Maximum specific growth rate and maximum specific substrate utilization rate for Monod model have been predicted as of the order of 0.153 g/g/day and 3.06 g/g/day , respectively, and those for Contois kinetic model were found to be 0.140 g/g/day and 0.421 g/g/day , respectively. However, for both the models the decay rate coefficient, was calculated as 0.0131 g/g/day. The estimated value of empirical constant in Contois model was found to be order of 0.699 (dimensionless). The deviation of model predicted values from experimental results has been compared. Sensitivity analysis of the developed models was carried out by considering 10% increase in the values of both and .
