Abstract
A compact vertical array of concentrically stacked and interfaced anaerobic digestion modules which comprise an anaerobic digestion sub-system. Each individual digestion module is an open-ended reaction vessel having an external flange on each end. Each pair of adjacent reaction vessels has a suitably sloped plate positioned at their interface and fastened to the bottom flange of the upper vessel and the top flange of the lower vessel. In this manner, each plate creates two individual digestion modules by serving as a bottom for the reaction vessel immediately above it and as a top for the reaction vessel immediately below it. Suitable openings are provided between adjacent digestion modules for transfer of digesting slurry from the module above to the module below. Each such opening is provided with a suitable valve for closing the opening during normal anaerobic digestion operations.
