Influence of Organic Loading Rate on the Process Imbalance of Anaerobic Digestion with Food Waste

摘要

The use of volatile fatty acids (VFAs) as process indicators in biogas reactors treating Food Waste (FW) was studied. The aim of this work was to determine a reliable parameter which could be used as an indicator of process imbalance during anaerobic digestion of FW in the continuously stirred tank reactors (CSTR) anaerobic reactor. It can be concluded from this that not only VFAs concentrations are indicator for process imbalance during anaerobic digestion of FW, but also VFAs changes constitute the most important indicators of early warning of process imbalances.
