CSO provides a range of Desulphurisation systems to remove hydrogen sulfide from Biogas. The G2G system is designed specifically for gas-to-grid applications where oxygen levels need to be restricted, the system does not utilize any chemicals and only requires a water supply for cleaning. The BIOC system is designed for CHP applications where oxygen levels are not a consideration and process water is available. CSO also offers dry chemical and ferric dosing systems for smaller flow/load applications.
