Biogas plant is a plant for energy production from biomass ; these renewable sources to be used to feed the digester are composed of organic substances that can be degraded anaerobically to produce biogas and biofertilizers. Anaerobic digestion is the degradation of organic substances by microorganisms under anaerobic conditions . Anaerobic treatment is advantageous in that the biogas is used in a cogenerative system for the production of electricity and heat , in addition to producing a biofertilizer with very good agronomic properties.
The plant in question is able to produce biogas through anaerobic digestion of effluents pigs , cattle, poultry , MSW , silage , etc and obtain electrical and thermal energy from the combustion of biogas in cogenerative system. The reception and pre – treatment will be the first compartment of the plant and will aim to get the biomass and feed throughout the day to the next phase of maceration. The effluent will be collected in a pre – load chamber , made of reinforced homigón.
The mix of organic matrices , mixed and homogenized with the mixer pump will be sent to anaerobic digestion controlled high performance . Anaerobic digestion will consist of one digester , called anaerobic or primary , which will be produced under conditions of controlled temperature homogenization and the degradation of the organic substance and the production of biogas. The degradation of biomass by microorganisms under anaerobic conditions takes place in the anaerobic digester and termofilia conditions at a temperature close to 50 ° C. The primary digester will be constructed in reinforced concrete conical bottom and will be thermally insulated to prevent heat loss stop.
