Every biogas plant requires a customized concept to remove hydrogen sulfide. We are happy to help find the solution that best suits the task, of course in collaboration with our customers.
We also have a biological filter material available that can be used to advantage immediately before activated carbon and in many cases can completely replace activated carbon. This biological material can handle the moisture in the gas and there is no need to cool the gas before filtration. With this filter material you reduce the CO2 footprint considerably and reduce power consumption. The content of H2s can not be higher than with activated carbon, but this filter material is, for example, suitable for purifying the biogas / CO2 gas down to a minimum of H2S.
