One of the services of Biogas Plus is the supply of aquafer to reduce the sulfur concentration (H2S) in your biogas. Sulfur gas is harmful to your CHP if it is present to a high degree. In the event that you use green gas, there may not even be any sulfur in the biogas. Biogas Plus can offer you to dose aquafer in your digester, so that the sulfur is bound and is not released into your biogas. The sulfur thus remains in the liquid and goes along with the digestate.
