(184i) Modeling Anaerobic Digestion of Biodegradable Solid Waste Conference: AIChE Annual MeetingYear: 2016Proceeding: 2016 AIChE Annual MeetingGroup: Liaison FunctionsSession: Undergraduate Research Forum II Time: Monday, November 14, 2016 - 2:30pm-2:45pm Authors: Malzahn, J. Skillings, D., South Dakota School of Mines and Technology Anaerobic digestion (AD) is the biological conversion organic matter into methane gas. The US Air Force aims to use this process to treat the biodegradable solid waste produced on their forward operating bases (FOBs). The focus of this study was to obtain the Monod kinetic parameters of AD process intermediates (volatile fatty acids, monomers, and polymers) that are typical of waste produced on FOBs. To obtain Monod kinetic parameters a combination of experimental and computational methodologies were applied. First, the AD of a single concentration of each of the substrate was regressed to obtain preliminary saturation constants (K s ) and maximum rates (µ max ) and next, these preliminary values were used to obtain actual experimental values. The experimental values obtained for the volatile fatty acids include: K s = 0.28 g L -1 , µ max = 0.00080 g COD g VSS -1 h -1 for acetic acid, K s = 0.22 g L -1 , µ max = 0.00049 g COD g VSS -1 h -1 for butyric acid, and K s = 0.089 g L -1 , µ max = 0.00031 g COD g VSS -1 h -1 for propionic acid. The parameter values obtained were within the range of previously reported literature values. Once all of the kinetic parameters are obtained, the parameters will be incorporated into the Anaerobic Digestion Model No.1 (ADM-1). ADM-1 predictions will be compared to batch AD performance for food waste, and model deficiencies will be discussed.
