How does the anaerobic digestion (AD) process work? WebAug 27, 2024 · Anaerobic digestion (AD) converts plant matter (biomass) into gas for use as a source of heat and electricity and more recently after upgrading to biomethane it is a sustainable renewable vehicle fuel. So, methane or biogas is the name of the gas. Bacteria (archae) generate it as a by-product of digesting biomass and producing methane.

Digestion units are either Mesophilic or Thermophilic; these terms refer to the temperature range within which the microorganisms work best. Mesophilic units operate at between 20-45°C, with an optimal temperature of 37°C. These are more common, as they are cheaper to build and maintain because of …
WebMay 8, 2024 · Aerobic digestion is the degradation of the organic sludge solids in the presence of oxygen. The oxygen is introduced as fine bubbles of air into the reactor. The micro-organisms in the sludge convert the organic material to carbon dioxide and water, and the ammonia and amino species to nitrate. Many microorganisms affect anaerobic digestion, including acetic acid-forming bacteria (acetogens) and methane-forming archaea (methanogens). These organisms promote a number of chemical processes in converting the biomass to biogas. Gaseous oxygen is excluded from the reactions by physical containment. Anae…
