How do Anaerobic Digester Systems work?
Feedstocks such as manure and green waste are deposited into the Reception Tank.
The Reception Tanks' chopper "blends" the feedstocks into a soup consistency.
The liquid is pumped into the Hydrolysis Digester and is heated to 60 degrees in the Hydrolysis Digester. Hot water from the CHP unit heats the liquid in the base of the Hydrolysis digester.
Once heated up the liquid is passed through the separator. Solids and liquids are then separated. Solids (compost) are disposed of in a skip or similar container and can be applied to fields instead of buying expensive fertiliser. Then the liquid is pumped into the Methane Digester.
The bugs in the Methane Digester are hard at work producing biogas.
Biogas is drawn into the CHP and will generate electricity and can either be used on-site or exported to the grid. Excess gas is used in the boiler to heat water, which is then pumped to the Hydrolysis unit, which heats the soup liquid.

How do Bio-Digesters Work?

Anaerobic digestion is a fermentation process that uses organic matter from animals, plants, or sewage to produce biogas. 

Anaerobic digestion for biogas production occurs in a sealed vessel known as a reactor, which is designed and built in a variety of forms and sizes based on the site and feedstock conditions. These reactors contain sophisticated microbial communities that break down (or digest) the waste and create biogas and digestate (the solid and liquid end-products of the AD process), which are discharged from the digester.
