Biological biogas desulfurization: natural bacteria remove H₂S without caustic soda, ferric chloride or activated carbon. What used to be waste is now energy and profit.
Natural sulfur-oxidizing bacteria of the family Thiobacillus. Acidithiobacillus oxidizes hydrogen sulfide (H₂S), the main contaminant in biogas, and works in synergy with Ferrooxidans for complete desulfurization. These bacteria are safe and environmentally friendly.
The bacteria attach to a special packing media and form a biofilm, a living layer where biogas is cleaned continuously. They only need water for moisture, nutrients (nitrogen, phosphorus and minerals) and a controlled dose of oxygen. They thrive at acidic pH, so no pH adjustment is needed.
AttachmentMicrocoloniesProtective matrixMature biofilm
Biological desulfurization produces sulfate (SO₄), which leaves through the drain, and elemental sulfur, which sticks to the packing media. With QSR®, the tank is filled with water and compressed air is injected: the packing is washed inside the tank, like a giant washing machine.
At a wastewater treatment plant the waste mix changes constantly: flow, contaminant load and H₂S fluctuate, with high and low seasons. Rigid chemical systems cannot cope with these swings and require constant manual adjustments.
Biogasclean adapts on its own, thanks to its biological flexibility and automatic operation. At a standard plant in Oregon, designed for 643 SCFM and up to 3,000 ppm of H₂S in a 14 × 31 ft FRP tank, the H₂S load varied between −21% and +32% every 15 minutes and the system kept operating.

BiogasBiomethaneLiquid biomethane
Modular systems designed and built by Cycle0 / Biogasclean, with no external licenses. From waste to final fuel in a single plant: biogas goes from a local fuel to a product that can be sold nationally and internationally.
CO₂ + H₂ → CH₄
Converts the CO₂ in biogas into additional methane with 97–98% purity, maximizing biomethane production.
Biogas enters with 4,000 ppm of H₂S and leaves with less than 50 ppm, over 98.75% removal without chemicals. Oxygen is dosed precisely (less than 22 Nm³/h, 92% purity) and residual O₂ stays below 0.3%. CO₂ is then removed to obtain grid-quality biomethane.
