Keeping Biogas Purification Systems Efficient with Sulphur Pumps | Global Pumps

Written by Carmen Vilchez | 25 November 2025

Hydrogen sulfide (H₂S) is one of the biggest challenges in biogas production. While biogas efficiently converts organic waste into energy, the presence of H₂S makes the gas corrosive and harmful to equipment. Removing H₂S during purification is essential to protect pipes, engines, and other components, ensuring safe and efficient biogas use.


How is sulphur sludge formed in biogas systems?

During biogas sulphurisation, H₂S is converted into sulphur sludge — a thick, sticky slurry that collects in the bioreactor. If this sludge is not removed promptly:

  • It can clog the system

  • Reduce overall process efficiency

  • Increase maintenance costs

  • Create a bottleneck in biogas operations

 

How do peristaltic sulphur pumps solve this problem?

Our peristaltic sulphur pumps efficiently transport sulphur sludge out of the bioreactor, ensuring smooth H₂S removal and allowing recovered sulphur to be reused as high-quality organic fertilizer.

 

WA Project Example:

For a recent biogas project, we delivered Dura 45 pumps with C5 coating. These pumps provide long-lasting corrosion protection and are ready to handle sulphur sludge in the purification system reliably.

WA project delivered: Dura 45 pumps, C5-coated for long-lasting protection, are ready to move sulphur sludge in a sulphur removal system within the biogas purification setup.

 

Why peristaltic pumps are ideal for H₂S removal:

  • Handles tough sludge: Thick, abrasive sulphur slurry passes through without clogging

  • Gentle and reliable: Ensures continuous flow without damaging equipment

  • Corrosion-resistant: Built to handle compounds produced during H₂S removal

  • Easy to maintain: Simple hose replacement reduces downtime

 

Which industries benefit from these pumps?

Our peristaltic pumps are suited for wastewater treatment, biomethane, and oil & gas industries, providing a reliable solution for handling chemicals and sludges.
