Canada’s Waterloo region has selected Suez’s ZeeLung technology for what will be the world’s largest membrane aerated biofilm reactor (MABR) system at the Hespeler Wastewater Treatment Plant in Ontario.

“This is a first-of-its-kind project for Canada that will demonstrate ZeeLung’s benefits: the ability to quickly and easily upgrade existing wastewater treatment plants on a cost-effective basis, with little disruption to on-going operations,” said Kevin Cassidy, executive vice president engineered systems for Suez Water Technologies & Solutions. “The technology allows customers to increase the treatment capacity of their plants, for a better water quality in a compact footprint while also reducing energy consumption.”

This new contract follows an 8-month pilot which demonstrated the ZeeLung technology and refined the design for full-scale implementation. The 9.34 MLD upgrade will be commissioned in 2021.
