Haskoning Announces First Full-Scale Ephyra® Sludge Digestion Project in Canada
International engineering firm, Haskoning, is set to implement its innovative Ephyra sludge digestion technology in Courtice for the Regional Municipality of Durham in Ontario. By retrofitting existing infrastructure, it will significantly boost the region’s sludge digestion capacity and efficiency. Driven by rapid population growth in the Greater Toronto area, the Regional Municipality of Durham is experiencing a significant rise in wastewater and sludge volumes. Traditionally, meeting these demands would require the construction of new, large-scale digesters, incurring substantial capital expenditure and lengthy planning and regulatory approvals. Ephyra offers a transformative alternative by allowing the Region of Durham to expand its processing capacity without building new assets. The technology enables the conversion of existing digesters into a high efficiency configuration, effectively doubling processing capacity within the same physical footprint. Although new to the Canadian market, Ephyra has already been successfully selected or implemented at 18 full-scale facilities across Europe, where it has proven to enhance both digestion capacity and gas production. At the heart of the Ephyra system is a unique configuration which divides an existing digester into three distinct compartments. Each compartment is designed to target different microbial processes in the breakdown of sludge – a method known as ‘phase separation’. This approach enables faster and more efficient digestion. “Ephyra allows municipalities to both significantly increase their sludge processing capacity without major new investments, and dramatically improve operational benefits by producing more biogas and breaking down more sludge. This project demonstrates how cutting-edge technology can overcome regulatory and capacity challenges while ensuring long-term environmental compliance and efficiency for communities,” commented Danny Traksel, sales director BioResources at Haskoning. Ephyra was successfully piloted in a project with the Region of Waterloo at the Waterloo Wastewater Treatment Plant (WWTP). This initiative was supported and validated by independent 3rd-party analysis from the University of Waterloo and led by Professor Wayne Parker, a leading professional in Canadian sludge management. The results confirmed Ephyra's strong performance and reliability. Additionally, Ephyra’s phase separation technology led to a 15-25% increase in biogas production and a 20-40% improvement in sludge breakdown compared to conventional digestion methods. These gains translate into higher operational revenues from renewable energy generation and lower costs for sludge disposal. For the implementation of Ephyra at Courtice Water Pollution Control Plant (WPCP), Haskoning will work together with CIMA+, a leading Canadian consultancy firm. CIMA+ has expressed strong enthusiasm for the project and sees significant potential for Ephyra across Ontario and Canada. “We see tremendous value in this technology for wastewater treatment plants throughout the Greater Toronto area,” said Troy Briggs, executive vice president of Infrastructure, at CIMA+. “Whether retrofitting aging infrastructure, expanding capacity at existing facilities, or designing new plants.”
