Keeping Biogas Purification Systems Efficient with Sulphur Pumps | Global Pumps

Written by Carmen Vilchez | 25 November 2025

Biogas production is an efficient way to turn organic waste into energy, but it comes with a challenge: hydrogen sulfide (H₂S). This corrosive gas must be removed in a biogas purification system before the gas can be safely used, as it can damage pipes, engines, and other equipment.

During the biogas sulphurisation system process, H₂S is converted into sulphur sludge, a thick, sticky slurry that accumulates in the bioreactor. If this sludge is not removed promptly, it can clog the system, reduce efficiency, and increase maintenance costs, creating a significant bottleneck in biogas operations.

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.

This is where our peristaltic sulphur pumps play a key role. They efficiently move the sulphur sludge out of the bioreactor, keeping biogas H2S removal running smoothly while allowing the recovered sulphur to be safely reused as high-quality organic fertilizer.

 

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 the system.

  • Corrosion-resistant: Designed to handle compounds produced during H₂S removal from biogas.

  • Easy to maintain: Minimal downtime thanks to simple hose replacement.

 

If you operate in wastewater treatment, biomethane, or oil & gas industries and need a reliable way to handle chemicals and sludges, our peristaltic pumps are designed for the job. Contact us today to learn more about our solutions.
