Biogas Production and the Importance of Pumps & Systems
Biogas production is a complex process that involves the anaerobic digestion of organic materials, such as agricultural waste, manure, and food waste. This process requires the movement and management of various substrates and byproducts throughout different stages, including feeding the digester, fermenter, recirculating digestate, and handling the output. The efficiency and reliability of these operations are heavily dependent on the quality of the pumping systems used.

Benefits: Protects downstream equipment from blockages, reduces maintenance costs, improves the efficiency of downstream processes, and handles large solids with ease.
Applications in Biogas Production
Pre-Treatment Process
- Feedstock Handling and Preparation: In biogas plants, organic waste materials such as agricultural residues, food waste, and manure need to be homogeneously mixed and prepared for digestion. NETZSCH N.Mac or M-Ovas Grinding Systems are used to shred the fibrous matter or solids in the raw feed and feeds to NEMO® progressing cavity pumps for consistent and reliable feed into the digester, preventing blockages and maintaining a steady flow process.
Gas Production Process
- Feeding the Digester: The pre-treated substrate is fed into the anaerobic digester where microbial activity breaks it down to produce biogas. The NEMO Progressing cavity pumps or TORNADO Rotary Lobe Pumps based on the space availability, can be used to feed the substrate into the digester at controlled rates, ensuring optimal loading and avoiding overloading flow.
- Recirculation: Within the digester, maintaining proper mixing and preventing sedimentation is essential for efficient biogas production. NEMO Progressing Cavity pumps facilitate the recirculation of the substrate, enhancing contact between the microorganisms and the organic material, thus improving biogas yield.
- Slurry Transfer: As the digestion process continues, the digested slurry needs to be periodically removed and transferred to storage or further treatment. Again, NEMO Progressing cavity pumps or TORNADO Rotary Lobe Pumps are employed for the efficient transfer of this sludge, handling its high viscosity and solids content effectively.
Gas Purification Process
- Condensate Removal: Biogas produced in the digester contains moisture that needs to be removed to prevent damage to downstream equipment. The NEMO Progressing Cavity pumps convey chilled water and assist the process in the removal of condensate from the biogas, ensuring it is dry before further purification steps.
- CBG to CNG Upgrading: CNG production focuses on increasing methane content and eliminating impurities from Compressed Biogas (CBG). Impurities such as H2S, CO2, and N2 are removed to achieve 96% methane purity. During this process, biogas is compressed to a pressure of 9-12 bar and fed into the desorption column. Chilled water is continuously introduced at a constant volume and pressure to separate the H2S, CO2, and N2 gases. The NEMO Progressing Cavity Pump is employed to reliably deliver the water at a consistent volume and pressure, facilitating the removal of these impurities.
