Anaerobic digestion process organic matter

Recently, anaerobic digestion (AD) has recovered the attention of the scientific community, since it represents a suitable and promising solution to reduce the organic matter and pathogenic organisms from wastewater [12]. Nevertheless, AD process is not widely applied at the industrial scale [36],... 

In the present chapter, anaerobic digestion (AD) is chosen as an illustrative example of biological WWTPs. It is a set of biological processes that take place in the absence of oxygen and by which organic matter is decomposed and converted on one hand into biogas i.e., a mixture of mainly carbon dioxide and methane) and, on the other hand, into microbial biomass and... 

The process of leachate formation in a landfill covers several phases, starting with initial decomposition to an acid forming period then to the methane formation phase. This biological process in which organic matter is catabolised to methane and carbon dioxide is anaerobic digestion. 

Anaerobic Digestion - The complex process by which organic matter is decomposed by anaerobic bacteria. The decomposition process produces a gaseous byproduct often called "biogas" primarily composed of methane, carbon dioxide, and hydrogen sulfide.
