BION - Model SIGMA -Removal of Hydrogen Sulfide (H2S) Filtration Media

BION SIGMA is a product for the removal of hydrogen sulfide (H2S). It consists of an iron hydroxide, Fe(OH)3, supported on a mixture of porous clays. BION SIGMA has been developed to work efficiently with biogas that has 90% or less relative humidity. In the absence of oxygen, BION SIGMA shows a higher H2S adsorption capacity than activated carbon impregnated with potassium hydroxide. BION SIGMA stands out for avoiding corrosion problems in equipment and minimizing the risk of fire thanks to its ignition temperature.
