ABSTRACT:
A reactor for the anaerobic digestion of organic sludge and for the production of methane gas, comprises an essentially horizontal cylindrical vessel provided with an agitator rotating around an essentially horizontal shaft, an inlet for introducing the sludge to be digested at one end of said vessel, at its opposite end an outlet for removing the digested matter from the vessel and in the upper portion of the vessel an outlet/outlets for the recovery of methane gas. For returning the solids settled on the bottom of the vessel from the outlet end of the vessel to the inlet end of the vessel, the vessel comprises a channel connecting the outlet end of the vessel with the inlet end of the vessel and a device for guiding the solids to the front of the return channel and for their transport through the return channel by means of gas.
