Type installationPurePac Arctic Medium

Oulu, Finland

The Oulu project is a PurePac Arctic and is designed to withstand extreme arctic weather, cold climate up to –40°C and a snow-load of one meter high. The biogas produced from sewage sludge and food industry waste streams is upgraded to biomethane through Bright’s PurePac system.

This PurePac Arctic Medium purifies 640 Nm³ biogas to roughly 400 Nm³ biomethane per hour which is used as Compressed Natural Gas (CNG).
