Biogas - Wikipedia

A biogas reactor or anaerobic digester is an anaerobic treatment technology that produces (a) a digested slurry (digestate) that can be used as a fertilizer and (b) biogas that can be used for energy. Biogas is a mix of methane, carbon dioxide and other trace gases which can be converted to heat, electricity or light.

Bioreactor - Wikipedia

The reactor contents are perfectly mixed together. The reactor is operating at a constant temperature (i.e., it is isothermal). The feed should be clean and pure (i.e., no biomass in the feed stream). The feed stream and reactor contents have equal and constant density (ρ). The feed and product streams have the same flow rate (F).

The Effect of Digested Manure on Biogas Productivity and .

As an anaerobic reactor, 500 ml serum bottle was used, which was sealed with a rubber stopper, and connected by the hose with a flowmeter to the biogas-gathering device. The constant-temperature water bath was used to maintain the fermentation temperature of ( )°C.
