Anaerobic Digestion: From Waste to Energy

Подробнее о видео

Anaerobic digestion is the process of micro-organisms breaking down organic material in the absence of oxygen (Anaerobic Digester).


From waste to energy that is main think when we talk about Anaerobic Digestion.

ANAEROBIC DIGESTION:
Organic waste material (for example food wastes or sewage sludge) is stored in an oxygen free environment (usually a sealed tank or container and commonly referred to as a digester) in the presence of a population of anaerobic micro-organisms.

In this anaerobic environment, biochemical reactions occur that convert organic polymers from the feedstock into methane rich biogas and nutrient rich digestate.

Anaerobic digestion works best at temperatures of 30 – 60°C. Between 30 and 40°C, mesophilic bacteria are the principal micro-organisms present. At 40 – 60°C, thermophilic bacteria are used.

The anaerobic digestion process typically takes anything between 14 and 40 days to complete but this varies upon numerous factors including feedstock type, micro-organism population, temperature and pH
