The township of Sherbrooke in eastern Quebec chose Aria FLEX custom water treatment system from Aria Filtra to update its aging water treatment plant.
The township of Sherbrooke in eastern Quebec was required to update its aging water treatment plant and find a solution that could be delivered and operational within a strict time limit. The existing drum filter microstrainers system was unable to meet new drinking water regulations set by the Ministry of Environment. The plant, which serves 145,000 residents, uses source water from Memphremagog Lake, which is protected and has water that does not contain much organic matter. However, the plant’s drum filters were unable to meet the new safety regulations because they were solely capable of filtering algae. For a solution, the plant was required to complete construction within Quebec’s stringent deadline in order to secure funding for the project.
Aria FLEX custom water treatment system from Aria Filtra® was selected following a successful preinstall bid and a pilot, in which it offered the best lifecycle costs and achieved the highest amount of water recovery, at 99.5%, compared to other systems. Reducing cryptosporidium and giardia was another key element of this project. Our membranes provided 4 log reductions beyond the 3 log reductions that were required of the city. With this reduction of solids, the robust Aria FLEX system has been able to reduce chlorination by 40%.
Not only was the Aria Filtra system able to meet drinking water standards and achieve compliance, but it was also able to exceed the plant’s original capacity of 81,000 m³/d, which had reached its limit and could no longer meet Sherbrooke’s growing capacity needs. The Aria FLEX membrane system is currently capable of producing 96,200 m³/d, but the system is poised to scale for a maximum capacity of 101,610 m³/d.
Case Study: Meeting New Drinking Water Regulations and Increased Capacity Needs with Robust Membranes
“From day one of the Aria Filtra pilot, the team at Sherbrooke's water treatment plant felt like a valued customer. While initially anxious about the prospect of implementing a new membrane technology—which no other cities in Québec were using at the time—our operators were convinced within the first few days of the pilot, due to how easy the system was to operate and the noticeable high quality of the water.” - Luc Larrivee, commander in chief for Water, Sherbrooke Water Treatment Plant
