  • Tubular digester
    Patent number: 9550702
    Abstract: Contiguous flow anaerobic digester for mechanization of organic matter and production of fertilizer powering the conditions and performance of the anaerobic digestion process, through homogenization of the sludge and process temperature, wherein the digester is tubular shaped and comprises a biogas exhaust valve at the top of the digester. One end of the digester has a sludge outlet connection, a water- and gas-tight zipper that is resistant to the corrosive elements of digestion, and an outlet. The opposite end of the digester has a mud inlet, and a water- and gas-tight zipper that is resistant to the corrosive elements of digestion, wherein said digester further comprises at its base a gas irrigation system for biogas recirculation composed of a polymeric material resilient to the corrosive elements of anaerobic digestion.
