Processing of the liquid fraction
Autothermal aerobic digestion
Objective
Biodegradation of organic matter by aerobic microorganisms sustained by the increase in temperatures up to 75 °C which favors the elimination of pathogens
Inlets
Liquid manure (pig and cattle); Slurry (Pork and cattle); Sewage sludge; Products from other processes: Separation by pressing and Aerobic digestion
Efficiency
Not available
Weaknesses
Ammonia emissions when not coupled to a nitrification-denitrification process;
Ammonium emissions increase at thermophilic temperatures;
Generating a large amount of sludge compared to anaerobic processes;
