Anaerobic digestion

Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process. AD stabilises the sludge biologically in the absence of air. In doing so, it reduces the amount of volatile solids by their conversion to a biogas (methane CH4, carbon dioxide CO2 and water H2O). The biogas then demands further processing for recovery and reuse of its methane content.

Biosolids vs sewage sludge

Biosolids are usually considered to be the useful fraction of the sewage sludge. They are generally higher in solids concentration and lower in pathogen content, having gone through a stabilisation process such as chemical dosing, digestion and/or drying.
