Processing of the liquid fraction

Autothermal aerobic digestion

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;

Products
