Hamel WTP, Victoriaville – Drinking Water Treatment

Victoriaville’s Hamel Water Treatment Plant plays a vital role in securing clean, safe drinking water for the community. The facility processes water drawn from the Beaudet Reservoir, a man-made basin created in 1976 following the damming of the Bulstrode River. Today, the plant serves as the city’s primary hub for drinking water treatment, ensuring consistently high-quality water for residents. On average, it treats nearly 12 million liters of water every day.

Objective

Pre-oxidation: enhance downstream flocculation and clarification, reduce the use of treatment chemicals, improve water taste and odor.

Intermediate ozonation: earn disinfection credits thus reducing the use of chlorine to that needed to establish a residual in the distribution network.

“Thank you for your hard work and your commitment to designing, delivering, and operating your technology. Your attention to detail is remarkable. We are truly dealing with people of great quality, the Primozone team.”

– Catherine Longpre, Mabarex

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.

Micropollutant removal with ozone, Birmensdorf

The Birmensdorf Wastewater Treatment Plant, located in Switzerland, has been in operation since July 1973. It serves several municipalities, including Aesch, Birmensdorf, Bonstetten, Stallikon, Uitikon, Wettswil, and parts of Aeugstertal. As part of a long-term development plan extending to the year 2035, the plant underwent a significant expansion between 2013 and 2018. This upgrade increased its treatment capacity to serve up to 33,000 population equivalents.

In response to the revised water protection legislation in Switzerland, the Birmensdorf facility has recently been modernized with an advanced treatment stage specifically designed to remove micropollutants from wastewater. These substances, which include trace pharmaceuticals and personal care products, are increasingly recognized as environmental contaminants that conventional treatment methods cannot fully eliminate.

To meet these new requirements, the plant implemented ozone treatment—a proven and efficient method for advanced wastewater purification. Ozone, a powerful oxidizing agent, breaks down complex organic compounds and significantly reduces micropollutant concentrations.

Objective

Reduce micropollutants in wastewater through ozonation and contribute to a safe and healthy environment for operators working on site.

“Together with Rheno AG, Primozone supply, install and commission ozone systems in a easy and safe way.”

Joined start up with experts from Primozone together with the application experts at Rheno.

At Birmensdorf, the ozone system was designed to treat a continuous wastewater flow of 464 liters per second. For this purpose, two ozone generators (model GM36) were installed, with a total ozone production capacity of 4.4 kilograms of ozone per hour. The ozone is evenly distributed into the water through high-performance ceramic diffusers, ensuring maximum contact and effective treatment.

The project was carried out by Rheno AG, which managed the detailed engineering, equipment delivery, installation, and commissioning of the ozone stage. This upgrade not only enhances the plant’s treatment performance but also ensures compliance with stricter environmental standards and contributes to long-term water protection in the region
