Thermophilic-dry anaerobic digestion

The interest in alternative municipal solid waste management strategies will likely intensify because its production continues to grow, while the disposal capacity via landfilling and incineration is disminishing. Anaerobic digestion has been used as a suitable treatment for organic wastes, including the organic fraction of municipal solid waste. Two residual effluents are produced: biogas, which can be used as an energy source, and a liquid effluent which could be used as a soil conditioner. The parameters employed, such as the percentage of COD removal, the concentration of volatile fatty acids and the amount and composition of biogas generated in the process, are not always representative of the composition and physiological state of biomass. This book, therefore, provides a new study about the concentration of principal groups of microorganisms involved in anaerobic depuration during start-up and stabilization of a thermophilic-dry anaerobic reactor by FISH. The analysis should be especially useful to professionals in Environmental Technologies and Microbiology fields, or anyone else who may be interesting in Environment Conservation
