Anaerobic processes are being explored for the production of bioenergy in the form of biomethane and biohydrogen in a "waste-to-value" approach that considers wastes as a resource. Laboratory scale Biomethane potential (BMP) tests and Up-Flow Anaerobic Sludge Blanket (UASB) reactors can be used to indicate the potential recovery of bioenergy from industry wastes. The goals of this research were to: (1) conduct a critical review of models for determining biomethane potential, (2) develop a theoretical relationship for stoichiometry for biomethane and biohydrogen from wastes, and (3) develop key design aspects for geometry and infrastructure, including gas-liquid-solid separation in laboratory UASB reactors. This research resulted in the development of a unified Process Flow Diagram, applicable for a variety of industry-relevant wastewaters. Also, in the process of achieving this goal the novel design of Gas-Liquid-Solid (GLS) separator for laboratory-scale UASB reactor was invented and manufactured utilizing the Fused Filament Fabrication (FFF) as an application of Additive Manufacturing. This dissertation can be used as a reference guideline for future investigators who start studying anaerobic digestion of industrial and municipal wastewater samples.
