In biogas extraction systems, FerroSorp® DG is often used for hydrosulfide separation. Since FerroSorp® DG is directly fed to the fermenting system together with the organic materials and then separates the hydrosulfide there, the biogas yield is hotter than in other processes (see process comparison).


In biogas systems from an electrical performance of 250 kW, FerroSorp® DG is usually delivered in big bags.
HERBST UMWELT TECHNIK offers a special conveyor and dosing system specifically for automated FerroSorp® DG withdrawal from the big bags and dosing of FerroSorp® DG in the storage container of the fermenting system or suspension reactor.


This system essentially includes the following assembly groups:


  • Big bag acceptance unit with electrical cable winch
  • Anti-congestion suction unit with suction lance, suction tube and electrical high-performance exhauster
  • Stainless steel storage container with level gauge and FerroSorp® DG dosing system in a performance range of 5 kg to 35 kg per cycle
  • Electrical control technology.

We provide the quality solution.
