Commercial Value

Abstract Volatile fatty acids (VFA’s) produced during anaerobic digestion of sludge have higher commercial value than methane produced subsequently. Therefore it was decided to determine conditions necessary to maximise production of VFA’s. Five anaerobic digesters were operated in parallel in the laboratory to investigate the effect of pH on the formation of VFA’s. Concentrations of individual fatty acids were measured. Both VFA production as well as gas production was favoured by pH approaching neutrality.
