Product Description

AD-20 Portable Digester for Continuous Anaerobic Digestion Testing

The portable digester AD-20 is designed to simulate the process of anaerobic digestion. This 20-liter bioreactor can perform continuous testing by controlling the mixing and the temperature. The AD-20 has multiple uses such as for your R & D projects, school training and simulate the process of the biogas plant.


Multiples Uses

Portable digester AD-20

  • Laboratories

For R & D projects like the development of feedstock recipes for digestion to the optimization of operational parameters.


  • Schools/Training

Excellent training system producing biogas in real time, offers an engaging education experience for students on the best practices of waste management and energy production. The AD-20 can produce up to 5 L of biogas with 1h of operation.


  • Pilot plant

A simulation tool for full scale biogas plant. Assesses the biogas yield of new substrates and evaluates the synergy effect of inputs variation on daily operation of the plant.



The AD-20 portable digester is robust, reliable, and versatile
