The PowerRing biogas plant is our specially developed biogas plant to fit your needs!

Main Advantages:

  • Dry matter input of up to 25 %
  • Optimized mixing technology
  • Fully thermally insulated
  • Usage of ag-wastes like stover, crop residues, etc.

The PowerRing is a highly efficient, 2-stage biogas plant which is suitable for operation with almost all substrates. Power output ranges from 7,500 MMBTU to 150,000 MMBTU per digester per year and a biomethane production of 80m³/h to 500m³/h. The design is based on an external main digester and an internal post-digester. The main digester is a ring canal, thereby allowing a controlled plug flow.

The PowerRing digester is equipped with a reinforced concrete roof with full insulation that guarantees the highest levels of thermal efficiency. Due to the compact design of the plant, the tank can be simply scaled to the size required according to the desired output and the type and quantity of substrate.

A special characteristic of the PowerRing system is its outstanding agitation technology which has already proven its worth during long-term operation in several reference plants. Scientific studies using simulations have determined the ideal positioning of the agitators in order to achieve the best possible level of mixing and minimum energy consumption. Their ease of accessibility and external motors makes servicing the agitators a very simple procedure.

Solid substrates are fed into the main digester using a solid substrate feed system, while liquid substrates are pumped. Using gravity and with no additional energy input, the fermented material (digestate) leaves the main digester via spillways, first into the post-digester and then to the final storage or intermediate buffer. The PowerRing draws on an extremely low proportion of the power it generates thanks to the agitator technique, feed in system and overall design.

The plant is completely automated and controlled via a user-friendly operating system. All the measurements and parameters which are of greatest importance to the biogas process are logged, allowing the plant processes to be recorded and permanently monitored on an ongoing basis.
