Anaerobic digestion of wood ethanol stillage using upflow anaerobic sludge blanket reactor
Journal Article

· Biotechnol. Bioeng. Symp.; (United States)
The anaerobic digestion of wood ethanol stillage in a UASB reactor was studied. At organic loading rates below 16 kg COD/m/sup 3/ day the reactor performed effectively, achieving soluble COD and BOD removals in excess of 86 and 93%, respectively. Removal of color averaged 40%. At a loading rate of 16 kg COD/m/sup 3/ day the methane yield was 0.302 L CH/sub 4/ (STP)/g COD removed, and the observed cell yield was 0.112 g VSS/g COD removed. Operation of the reactor at higher loading rates was unsuccessful. Nitrogen, phosphorus, and alkalinity were supplemented. No additions of the essential trace elements Fe, Co, and Ni were required.
