What type of H₂S adsorbent do I need for biogas purification?

There are different adsorption methods to remove H₂S from biogas: solid media, biological scrubbing or chemical scrubbing. Selecting the appropriate one depends on parameters such as flowrate and H₂S concentration. In general terms, fixed iron bed solid media, such as SULFURTRAP^® , are used for low flow rates and low H₂S levels.
