Using its bolted steel tank technology, APRO provides reliable, durable installations tailored to the needs of both industrial clients and local government.

Our Solutions for Methanisation, Digestion, and Fermentation

Anaerobic Digesters

Our steel digesters are designed to optimise biogas production while ensuring the stability of the biological process. Compatible with various types of roofs and agitators, they offer robustness and flexibility for all types of effluents.

Hydrolysis Tanks

APRO Industrie hydrolysis tanks facilitate the initial stage of organic matter degradation, which is essential for maximising methanisation efficiency. Their modular design enables them to be seamlessly integrated within the unit.

Post-Digesters

Our post-digesters facilitate continued fermentation following the primary digestion process. This enables maximum energy recovery from the substrate while ensuring the stability of the digestate.

Digestate Storage

Our storage tanks have a capacity of up to 10,000 m³ of digestate. Thanks to their coated steel construction, they offer excellent resistance to aggressive environments and the mechanical stresses associated with large volumes.

Sludge Tanks and Degassing Towers

APRO Industrie also designs sludge tanks and degassing towers. These are key components for complete methanisation installations, ensuring site safety and performance.

Technical Features of Our Solutions

Thanks to their bolted steel construction, our tanks can be built up to 45 metres in diameter and 30 metres in height, with a diameter-to-height ratio greater than 0.3. A variety of coatings provide optimal resistance to corrosive gases and high temperatures. They offer quick assembly, a service life of over 30 years and minimal maintenance.

FAQs - Methanisation, Digestion, and Fermentation

Our customers often wonder about the capacity, maintenance, and operating conditions of our equipment. Here are some answers to the most common questions to guide you in your project.

What is the maximum capacity of methanisation, digestion, and fermentation solutions?

Our digesters and digestate storage units have a capacity of up to 10,000 m³. Thanks to their modular design, they can be adapted to suit your needs.

How are methanisation, digestion, and fermentation tanks maintained?

The bolted steel structure provides easy access to the equipment, ensuring that maintenance is simple and infrequent. The high-quality materials ensure a service life of over 30 years with minimal maintenance.

What are the optimal conditions for methanisation, digestion, and fermentation?

Our solutions are designed to work with various effluents under different temperature and composition conditions (e.g. chlorides and H₂S). The choice of coating is adapted to these constraints to ensure optimal performance.
