Hamel WTP, Victoriaville – Drinking Water Treatment

To maintain the highest possible water quality, the Hamel Water Treatment Plant integrates ozone into two essential stages of its drinking water treatment process. The first stage is pre-oxidation, where ozone helps improve flocculation and clarification. By breaking down organic matter and aiding particle aggregation, ozone enhances the efficiency of the clarification process while reducing the overall need for chemical coagulants. This step ensures that the plant can achieve optimal water clarity with a more sustainable chemical footprint.

The second stage is intermediate ozonation, a powerful and reliable method for water disinfection. Ozone effectively inactivates a broad range of microorganisms, including bacteria, viruses, and protozoa, providing an additional layer of protection beyond traditional chlorination. By integrating ozone at multiple points in the process, the plant ensures consistent water quality, taste, and safety for residents throughout the year.

In 2023, the City of Victoriaville approved a major upgrade to the plant’s ozonation system, demonstrating the central role that ozone technology plays in their long-term water strategy. As part of this modernization effort, the facility installed a new Primozone ozone system with a capacity of 8.64 kg/h. This high-efficiency system is designed not only to improve operational reliability but also to support the plant’s future expansion. With this upgrade, the Hamel plant is expected to be capable of treating nearly 42 million liters of water per day, more than tripling its current average output.
