Scotland Wastewater Facility Achieves 85% Energy Self-Sufficiency
The Seafield Wastewater Treatment Works plant in Scotland achieved a 85% energy self-sufficiency throughout 2017. The plant was able to successfully increase its onsite power generation from 55%.
To operate the system, an anaerobic digestion plant provides sludge that provides power along with biogas found at the plant itself. This specific powering approach allowed the plant to operate entirely independent of the grid at several points throughout the year.
The plant is able to utilize this sludge by employing a variety of methods to extract the power that it provides. Of the various processes utilized, the plant has increased its biogas output by 10% by implementing a thermal hydrolysis process while also installing an additional combined heat and power system to more efficiently use their increased biogas yield.
