Case Study: Aria FLEX Custom Systems – Sherbrooke, Canada

Case Study: Sherbrooke, Canada

Municipal Water Treatment – Drinking Water | North America: Sherbrooke, Quebec, Canada

 

The township of Sherbrooke in eastern Quebec was required to update its aging water treatment plant. 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. While the lake itself is protected and the water does not contain much organic matter, the plant’s drum filters were unable to meet the new safety regulations because they were solely capable of filtering algae. For a solution, time was of the essence as the plant was required to complete construction within Quebec’s stringent deadline in order to secure funding for the project.

 

Pall Water’s Aria FLEX custom water treatment system was selected following a successful pilot where it offered the best lifecycle costs and achieved the highest amount of water recovery. The robust membranes were able to meet drinking water requirements and the system was built to scale for future capacity needs.

  • The Challenge

    Sherbrooke needed to update its aging water treatment plant and find a solution that could be delivered and operational within a strict time limit. New regulations required Sherbrooke’s water treatment plant to reduce turbidity by meeting limits of 0.2 NTU from the previous limits of 5.0 NTU, thus requiring the plant to deploy a much more robust system to attain compliance. The system would also be required to achieve 0.1 NTU 95% of the time, and 0.2 NTU 100% of the time.

  • The Solution

    Pall Water’s Aria FLEX custom water treatment system was selected following a successful pre-install bid selection and a pilot where 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. Pall Water’s 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%.

  • The Results

    Not only was the Pall Water 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 was no longer able to meet Sherbrooke’s growing capacity needs. Pall’s 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.

  • Service & Maintenance: Aria CARE

    Initially, the Sherbrooke team was anxious about investing in innovative membrane technology, which was new at the time. However, the Pall Water team was very transparent, providing a hands-on pilot that quickly convinced the engineers to trust the technology after seeing results. Critical to the success of the pilot was Pall’s local approach and active role. With technicians that spoke French, the Pall Water team was able to avoid any language barriers and explain how the technology functioned, while helping operators get comfortable running the system.
