Scottish Water WWTP becomes self-sufficient

Utility Scottish Water is progressing towards energy self-sufficiency at its Seafield Wastewater Treatment Works.

Utility Scottish Water is progressing towards energy self-sufficiency at its Seafield Wastewater Treatment Works. Last year, the site was generating 85 percent of its own energy after Veolia boosted the renewable energy derived from a combination anaerobic digestion of sludge and biogas fired combined heat and power (CHP). Measures installed to date at the site include a thermal hydrolysis process that has increased biogas production by around 10 percent and investment in an additional CHP unit to provide greater energy generation and to take advantage of the additional biogas. Recent estimates indicate that the water industry could be self-sustaining for electricity by harnessing the 11 billion litre annual flow of wastewater.
