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.
Fluence continues expansion in China
Fluence Corporation has signed a framework agreement to deliver six Smart Packaged wastewater treatment plants based on Fluence’s MABR technology (C-MABR) with partner Jiangsu Jinzi Environmental Science and Technology Company. The wastewater treatment projects are part of a public/private partnership in China’s Guizhou province. The agreement encompasses a total of six wastewater plants designed to deploy Containerised Smart Packaged MABR (C-MABR) technology ranging between 600 to 1,000 m3/day. The plants, which are part of a multi-million-dollar order, are expected to be delivered, installed and become operational during 2018.
