The breakdown of carbohydrates. Carbohydrates in feedstocks. Bacteria concerned in polysaccharide digestion. The metabolism of nitrogen compounds. Metabolic pathways and the bacteria involved in protein metabolism. The metabolism of fatty acids, lipids and hydrogen, and production of methane. Methane production. Some inhibitions of digester bacterial reactions. Startup of digesters. The 'rumen' digester -- Ch. 3. Mathematical Models. The economic and engineering model. The biological model. General considerations. The stirred-tank digester. Steady-state models. The steady-state digester model. Dynamic models. Some other models. Retained-biomass digesters. Two-phase and two-stage digesters. Tubular digesters -- Ch. 4. Types of Digesters and their Construction. Design and operation. Sludge and slurry digesters. Mixing. Heating. Loading rates. The Contact digester. Anaerobic filters. The upflow sludge blanket (UASB) digester. The fluidised-bed digester. Other types. Construction. Concrete. Enamelled steel. Steel tanks. Plastics. Rural digesters. Gas holders. Digester overflow and secondary tanks -- Ch. 5. Pretreatment of Feedstocks. Physical pretreatments. Removal of digestible solids, or of liquids. Removal of non-biodegradable solids. Mainly biological pretreatments. Particle-size reduction. Chemical, with or without physical, pretreatments -- Ch. 6. Digestion of High-Solids Feedstocks. Simple and modified batch digesters. Fed-batch digesters. Continuous-flow stirred tanks. The climatically-heated, small-farm digester. The 'standard' stirred-tank sewage digester.
