Gas collection cover will help power pulp mill
2014-09-06 -- Work is wrapping up on GTI's involvement with the Slave Lake Pulp project.
The custom-designed cover and liner system complements the design of the anaerobic reactor selected to pretreat the pulp mill’s wastewater.
GTI’s gastight cover will capture the biogas from anaerobic treatment of the mill effluent and deliver the gas for use in three electrical generators. The power generated will greatly offset the plant operating costs. At the same time, the cover protects against the release of greenhouse gases and negative odors associated with effluent treatment.
The reactor cover is insulated, which will help maintain the proper temperature for anaerobic digestion through the cold winter months of northern Alberta.
The durable and buoyant design allows operators at the mill to walk on the cover and have easy access to built-in sampling ports. The cover also has an efficient rainwater collection and drainage system.
