Design and construction of biogas digester

Once the feedstock is collected and prepared, it is introduced to the anaerobic digester, which is sometimes referred to as an anaerobic reactor. Given the specific type of manure collection system, the digester is designed to provide the optimal conditions for converting the organic waste into biogas. See more Manure is collected and placed in a centralized location in a way that is compatible with biogas recovery. Co-digestion feedstocks, such as food processing waste … See more The waste handling system prepares the feedstock for use in the anaerobic digester. Depending on the type of feedstock and the type of digester, pretreatment may be required. Pretreatment steps … See more Captured biogas is transported through a pipe from the digester, directly to a gas use device or to a gas treatment system. In most cases, the only treatment needed is to remove excess moisture prior to combustion. … See more Digested solids(known as fiber for farm-based systems) can be removed from the digester effluent with a solids separator.
