Anaerobic digestion is one of the effective methods of treating biosolids from municipal and industrial wastewater. It is an ideal method in meeting strict environmental regulations in highly urban areas. The anaerobic process occurs in closed vessels (digesters), or covered ponds or lagoons. Soluble organics are converted to methane (CH4) and carbon dioxide (CO2) in a two-step process.
Biogas collection and utilisation is an important part of the anaerobic digestion process. The low heat content gas is saturated, and contains elements harmful to personnel. Biogas is also corrosive to piping and equipment. It is important to handle biogas properly to ensure a protected environment. The key aspect of design is to recognise that biogas handling equipment operates as a system.
