The use of activated carbon allows the biogas to reach the required quality for valorization, whether in cogeneration, purification, or bioGNV.

Activated carbon, used at the outlet of digesters, helps eliminate contaminants in the biogas, such as hydrogen sulfide (H2S) and many volatile organic compounds, which are corrosive to our engines (causing oil acidification).

For any order of activated carbon, please do not hesitate to contact us by email at sav@agripower-france.com.

The oil filters, present in thermal engines, must be changed at each engine oil change.

The air filters, present in cogeneration engines, must be changed regularly to ensure the proper air supply necessary for the perfect combustion of biogas in the thermal engine.

For any filter orders, please do not hesitate to contact us by email at sav@agripower-france.com.

Spark plugs must be replaced during each engine maintenance. This component is essential for the operation of the cogeneration engine.

A defective spark plug will prevent the proper start-up of the cogeneration, can clog the exhaust system, contribute to air pollution, and limit the operating power of the installation.

It is important to regularly check and adjust combustion equipment. Please contact Agripower FRANCE to order your maintenance consumables and to learn about our various maintenance contracts.

Oil is essential for the proper functioning of the cogeneration engine and to ensure an optimal lifespan. Here are the benefits of high-quality oil :

• Reduces valve wear

• Very little deposit on pistons and sludge formation

• Increases the lifespan of spark plugs

• Optimizes oil change intervals and lifecycle costs

• Reduces maintenance costs

Iron hydroxide is used to reduce the formation of hydrogen sulfide in the bioreactor of the anaerobic digestion unit. The high iron content and purity of this product will decrease the presence of hydrogen sulfide in the biogas.

Iron hydroxide is introduced into the digester via the insertion hopper or the input incorporation pump.

For any iron hydroxide orders, please do not hesitate to contact us by email at sav@agripower-france.com.

The inputs used for anaerobic digestion (slurry, manure, biowaste, sludge, etc.) do not all contain the necessary trace elements to optimize biogas production.

It may be necessary to add trace elements to the digester if there is a proven deficiency of certain trace elements. To determine this, we offer digestate analysis (the material undergoing digestion) to detect any deficiencies.

Depending on the type of deficiencies, we can then offer you a customized trace element treatment.

During fermentation, it can sometimes be challenging to break down components such as proteins, cellulose, starch, or hemicellulose. This can extend the time required to transform waste into biogas.

The addition of enzymes can effectively accelerate the decomposition process and enable the bacteria involved in biogas production to perform their work.

The enzymes offered by Agripower FRANCE will help reduce viscosity, increase mixing ability, and improve fluidity.

For any enzyme orders, please do not hesitate to contact us by email at sav@agripower-france.com.

If foam appears in the digester, we recommend using the non-mineral, silicone-free liquid antifoam treatment.

Our product will eliminate the substances that generate foam around the gas bubbles, destroying the foam layer on the surface of the digester.

For any questions and inquiries about foam formation, please do not hesitate to contact us to be guided by an expert.

For any antifoam orders, please do not hesitate to contact us by email at sav@agripower-france.com.

The agitator is the component that ensures the homogeneous mixing of organic materials inside the digester.

In case of an agitator malfunction, Agripower FRANCE can offer you a replacement for this part.

For any agitator orders and to learn about our various maintenance contracts, please do not hesitate to contact us by email at sav@agripower-france.com.

Pumps facilitate the transfer of liquid inputs and digestate from one tank to another.

In case of a malfunction, it is essential to replace this part. Agripower FRANCE offers you a replacement for this part.

For any pump orders and to learn about our various maintenance contracts, please do not hesitate to contact us by email at sav@agripower-france.com.

The heat exchanger ensures the transfer of heat between two fluids while preventing them from mixing.

In case of a malfunction, Agripower FRANCE offers you a replacement for this part.

For any heat exchanger orders and to learn about our various maintenance contracts, please do not hesitate to contact us by email at sav@agripower-france.com.

The thermal engine combined with a generator constitutes the cogeneration unit. The thermal engine uses biogas, purified of its harmful compounds (via activated carbon), as fuel. This drives the generator, which in turn produces electricity.

These engines require regular maintenance.

Agripower FRANCE can handle this maintenance and, during these interventions, Agripower FRANCE may carry out engine adjustments, such as valve timing or cylinder head replacement.

In case of a malfunction, we offer standard exchanges of reconditioned or new engines. Agripower FRANCE is committed to the circular economy and aims to reduce waste, which is why we strive to offer as many reconditioned parts as possible.

For any engine orders and to learn about our various maintenance contracts, please do not hesitate to contact us by email at sav@agripower-france.com.

The generator is the part of the cogeneration unit that, driven by the thermal engine, produces electricity. Therefore, the generator is a critical component within an anaerobic digestion unit, as it enables the generation of revenue from the anaerobic digestion unit. With Agripower FRANCE’s biomethanation installations operating over 8,000 hours per year, the generator is heavily used and may experience wear. Maintenance and replacements are therefore to be expected.

Agripower FRANCE's teams, with 10 years of experience, are capable of identifying signs of wear and can thus offer standard exchange solutions for reconditioned or new generators. Agripower FRANCE is committed to the circular economy and aims to reduce waste, which is why we strive to offer as many reconditioned parts as possible.
