for the removal of hydrogen sulfide from landfill gas and other methane gas mixtures.

Designed as a single or multipass biotrickling filter, the BIOREM Biogas Sweetening system utilizes special bacterial species tailored for the removal of H2S in oxygen deficient atmospheres.

The gas mixture is forced into intimate contact with a specially selected, high porosity media and the hydrogen sulfide is solubilized into the biofilm.

Special sulfur degrading bacteria use the H2S as a food source and convert into elemental sulfur and sulfate.
