  • Process for the biologic treatment of organic wastes and plant therefor
    Patent number: 8734647
    Abstract: Process for the biological treatment of organic wastes, includes a first anaerobic digestion phase and a second aerobic digestion phase in succession, a respective filtration phase of the solid substance being provided between the two digestion phases, a separation phase of the biogas released in the anaerobic digestion phase and a nitrogen recovery phase from the exhaust gases rich in ammoniac substances separated from the aerobic digestion phase. The solid substance coming from each of the filtration phases is separately returned to the respective digestion phase, while the liquid phase coming from the filtration phase downstream of the anaerobic digestion phase is sent to aerobic phase. In the nitrogen recovery phase the gaseous current consisting of exhaust gases rich in ammoniac substances is treated with a solution of carbonic acid supplied in countercurrent in a first gas/liquid contactor to obtain a mixture of nitrogen salts (ammonium bicarbonate, ammonium carbonate, etc.).
    Type: Grant

    Date of Patent: May 27, 2014
    Assignee: Bioenergia S.r.l.
    Inventors: Paolo Bresciani, Andrea Manfredini, Andrea Peri, Federico Peri, Mario Peri, Vanessa Pizzaballa, Martino Pretalli, Antonio Tabarelli, Antonio Trilli
