Abstract (en)

[origin: WO2007059777A1] Device and method for biogas production by digestion of waste water or manure. The device consists of four compartments and the substrate is led to flow from the first via the second and third, to the fourth tank. The tanks contain a mesh where microorganisms effecting the methanation are immobilised. The method is caracterised by the start-up procedure during which the digester is fed to a certain extent with degraded substrate, ie methanation feed. In consequence the growth rate of methanation microorganisms is increased, ensuring a high concentration of methanation organisms in the digester.
