Özet

In this study, biodegradation of dairy wastewater was investigated under aerobic conditions in a batch reactor. A minimum concentration of 100 mg L-1 and a maximum concentration of 1000 mg L-1 of COD in the wastewater were used. The culture substrate removal kinetics was followed and the specific growth rate was fitted to the Monod model. The kinetic coefficients KS and ae max were found to be 46.55 mg L-1 and 0.0344 h-(1,) respectively. The regression coefficient was 0.99. The compatibility of actual and predicted results of microbial growth and substrate removal was compared with this model. Results indicated that predicted and actual values fitted each other with 89% compatibility.
