Abstract

A steady state model for cheese whey fermentation in two series of reactors has been developed. The model was derived based on mathematical and fundamental chemical engineering concept. The aim of this research is to develop the model for cheese whey fermentation in two series of reactors and to investigate the effect of hydraulic retention time on process performance. This research showed that the recommended values of hydraulic retention time for the second reactor decreased as the inlet substrate concentration increased. The results were 14, 7, and 2 h for 50, 100, and 150 g/l inlet substrate concentration. Another important result was the significant reduction of substrate and slightly higher values of ethanol concentration obtained by combining two reactors in series compared to the use of single reactor.
