2037731-A is referenced by 5 patents.

The reactor is a horizontal cylindrical vessel (1) in which an agitator (13) rotates around a horizontal central shaft (2). The vessel has an inlet (6) for sludge to be digested at one end, an outlet (7) for digested sludge at the opposite end, and a discharge pipe (9) in its upper part for methane. Partitions (10), attached to the agitator to rotate therewith, divide the vessel longitudinally into chambers, the last of which forms a settling chamber (14) which contains return pipe means (17) for returning part of the solid matter settled in the settling chamber to one of the chambers at the inlet end of the vessel. The pipe (17) extends at an angle to the shaft (2) and rotates with it. The return means includes a scraper (18) for pushing settled solid matter into the return pipe.
