In 2014, the City of Sherbrooke, Quebec, sought to upgrade its water treatment plant sourcing from the Magog River. The existing ozone equipment had reached the end of its operational life, necessitating a replacement to ensure effective disinfection and maintenance of water quality standards. After evaluating available options, Sherbrooke selected Pinnacle Ozone Solutions’ Zenith series ozone generator system for its superior functionality and cost-effectiveness. The installation included three Zenith 20X ozone generator platforms, each capable of producing approximately 280 pounds of ozone per day (5.3 kg/hr). This modular design not only met the current ozone demand but also allowed for up to 15% future expansion by adding new ozone cells if required. The system was configured to operate with two units active and one on standby, ensuring redundancy and reliability.
Background
The Sherbrooke water treatment plant historically utilized ozone technology to address seasonal organics, color, taste, and odor issues in its water supply. By 2014, the existing ozone equipment had reached the end of its operational life, necessitating a replacement to ensure continued effective disinfection of pathogens and maintenance of water quality standards. After evaluating available options, Sherbrooke selected Pinnacle Ozone Solutions’ Zenith series ozone generator system for its superior functionality and cost-effectiveness.

Approach
The installation included three Zenith 20X ozone generator platforms, each capable of producing approximately 280 pounds of ozone per day (5.3 kg/hr). This modular design not only met the current ozone demand but also allowed for up to 15% future expansion by adding new ozone cells if required. The system was configured to operate with two units active and one on standby, ensuring redundancy and reliability. Integration into the existing operations was seamless, as the new system replaced the outdated equipment without significant modifications. Pinnacle’s Ozone-On-Demand technology enabled precise, real-time control of ozone production, automatically adjusting output to match the plant’s varying demands.
Results
Since its commissioning in the spring of 2014, the Pinnacle ozone system has exceeded expectations in performance, reliability, and operating costs. The advanced design of the Zenith series, featuring maintenance-free ozone cells and high energy efficiency, resulted in significant operational savings. The system’s ability to produce consistent ozone concentrations at any turndown level improved ozone transfer efficiency across all operating points. An unexpected benefit was the reduction in operational expenses compared to the previous system. The plant experienced lower maintenance requirements and seamless control, reducing overall labor costs. The reliability and efficiency of the new system have ensured compliance with water quality standards while optimizing resource use.
