Pumping solutions for biogas applications
Biogas producers play a critical role in the transition to greener energy, thus contributing to environmental protection.
PCM offers robust and high-performance biogas pumping solutions, specially designed to meet the requirements of biogas plants, facilitating the recovery of organic waste.
Challenges in biogas applications
PCM pumping solutions in the process of Biogas Production
Storage and transfer of raw materials
Before they are introduced into the digesters, raw materials such as slurry, manure and food waste are stored. These materials are often very dense, viscous, and abrasive, requiring robust pumping solutions.
Digester feed and fermentation
Organic matter is sent to digesters where it ferments and produces gas. To facilitate fermentation, part of the fluid can be transferred from one digester to another, allowing the process to be started in another digester. At this stage, the organic matter is not fully digested, so the transferred fluid is particle-laden and highly viscous.
Recirculation
The digestate is pumped into the digesters and then fed back into the hopper pump body. Mixing the raw materials with the digestate liquefies the mixture for easy transfer. A high proportion of dry matter in the raw materials can cause clogging during transfer to the digesters.

Hygienization
Pasteurization or sanitization is a crucial step to ensure the safety of certain raw materials, such as animal by-products that must be transferred from their storage area to the sanitization tank to be crushed, heated and treated, to eliminate pathogens before they are digested.
Transfer of digestate
After fermentation, the digestate must be transferred to the separating machines, to reduce the water content of the digestate.
Phase separation
The digestate is separated into solid and liquid fractions, making them easier to store and spread.
Digestate discharge
The liquid digestate is evacuated and then transferred to the fields to be spread and used as fertilizer in agriculture. This step may require transferring fluids over long distances.
