Preliminary Evaluation of the Pretreatment of Fuel Alcohol Fermentation Stillage through an Anaerobic Filter

摘要

The objective of this research was to conduct a preliminary evaluation of the pretreatment of fuel alcohol fermentation stillage by means of an anaerobic filter. The first phase of the investigation was devoted to characterizing the stillage. The second phase of the investigation studied the reduction of suspended solids by centrifugation. In the third phase of the investigation laboratory scale anaerobic filters were tested as a means of pretreating the fermentation stillage. Overall, the anaerobic filter was demonstrated to ben an effective means of pretreating fermentation stillage.
