Documentation

Application Sheet - Digesters / Biogas Tanks

With expertise dating back to 1987, APRO Industrie designs and builds tailor-made solutions for digestion and fermentation. Using its bolted steel tank technology, APRO provides reliable, durable installations tailored to the needs of both industrial clients and local authorities.

Our Solutions for Digestion and Fermentation

Digesters

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

Hydrolysis Tanks

APRO Industrie hydrolysis tanksfacilitate the initial breakdown of organic matter, which is essential for maximising digestion efficiency. Their modular design enables them to be seamlessly integrated within the unit.

Post-Digesters

Our post-digesters facilitate continued anaerobic digestion following the primary digestion process. This enables maximum energy recovery from the feedstock while ensuring the stabilisation of the digestate.

Digestate Storage

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

Sludge Tanks

APRO Industrie also designs sludge tanks. These are key components for complete anaerobic digestion plants 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 excellent resistance to corrosive gases and high temperatures. They offer fast installation, a service life of over 30 years and low maintenance requirements.

FAQs - 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 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 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 digestion and fermentation?

Our solutions are designed to operate with a wide range of effluents under different temperature and composition conditions (e.g. chlorides and H₂S). The choice of coating is selected to suit these operating conditions to ensure optimal performance.
