CSO provide a range of Desulphurisation systems to remove hydrogen sulphide from Biogas. The G2G system is designed specifically for gas to grid applications where oxygen levels need to restricted, the system does not utilise 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 offer dry chemical and ferric dosing systems for smaller flow/load applications.
