Anaerobic Digestion: What Takes Place in the Anaerobic Digester

Подробнее о видео

Anaerobic digestion is the process by which organic is broken down to produce biogas and biofertiliser. This process happens in the absence of oxygen in a sealed, oxygen-free tank called an anaerobic digester.


ANAEROBIC DIGESTER:
Inside an anaerobic digester, naturally occurring microorganisms grow in the tank’s oxygen-free environment and break down (digest) the organic matter. As the organic matter decomposes, biogas is created. Once established in a digester, microorganisms will continue to break down organic materials and release biogas in the right conditions. The microorganisms need a steady supply of feedstock and a comfortable environment - warm temperatures, neutral acidity and no oxygen.
Biogas is the gas produced when bacteria break down organic matter in the absence of oxygen. It is made up of mainly methane (CH4) and carbon dioxide (CO2), with small amounts of water vapor, particulates, and other gasses, such as hydrogen sulfide (H2S). Biogas can be processed and used for a variety of energy needs, such as the generation of heat, power and fuel.
