Why Sherbrooke, Quebec Chose Pinnacle Zenith Ozone Generators To Boost Water Treatment Efficiency

In 2014, the City of Sherbrooke, Quebec, recognized the need to upgrade its water treatment plant sourcing from the Magog River. The facility’s existing ozone equipment had reached the end of its operational life, threatening its ability to maintain consistent disinfection and water quality standards. After evaluating multiple options, Sherbrooke selected Pinnacle Ozone Solutions’ Zenith series ozone generator system for its performance, reliability, and cost-effectiveness.

The installation included three Zenith 20X platforms, each producing approximately 280 pounds of ozone per day (5.3 kg/hr). The modular design allowed two units to operate while one remained on standby, ensuring redundancy and uninterrupted operation. Additionally, the system accommodated up to 15% future expansion by adding new ozone cells, providing flexibility for growing demand. Pinnacle’s Ozone-On-Demand technology enabled precise, real-time adjustments, automatically matching ozone output to the plant’s variable operational needs.

Since commissioning, the Zenith system has delivered exceptional results. Its maintenance-free ozone cells and high energy efficiency have reduced operational costs while improving reliability. The system consistently maintains target ozone concentrations across all turndown levels, enhancing mass transfer efficiency and optimizing water treatment. Labor requirements and maintenance downtime have decreased significantly, allowing operators to focus on other critical tasks.

By combining advanced technology, operational efficiency, and future-ready scalability, Pinnacle’s Zenith series has enabled the Sherbrooke water treatment plant to maintain regulatory compliance, improve water quality, and reduce costs—demonstrating a modern, sustainable approach to municipal ozone treatment.
