Success Story: Pyure’s Hydroxyl-Generating Technology Reduces Hydrogen Sulfide Emissions in Wastewater Treatment Facilities

Tackling Odor Control Challenges

Two wastewater treatment facilities in Ontario—the City of Sarnia’s Devine Street Sewage Pumping Station and the Courtice region’s Water Pollution Control Plant (WPCP)—faced significant challenges with hydrogen sulfide emissions (H2S). These emissions led to severe odor control issues. The City of Sarnia experienced numerous complaints from nearby property owners due to odors emanating from a newly expanded 56,000 L sanitary sewage pumping station. Similarly, the Courtice WPCP struggled with H2S release in its upper vault, causing odor problems and corrosive contamination within its treatment spaces. These issues impacted community well-being and posed risks to the infrastructure’s integrity.

Pyure’s Innovative Solution

Both facilities turned to Pyure’s hydroxyl-generating technology to address these challenges. This innovative solution employs natural hydroxyls and oxidants to neutralize odors. Learn how Pyure works here.

City of Sarnia

The City of Sarnia implemented a trial of the system, which proved successful, leading to the purchase and permanent installation. The results were remarkable, significantly reducing hydrogen sulfide emissions and effectively addressing the odor problem.

Courtice WPCP

At the Courtice WPCP, introducing hydroxyl generators reduced H2S concentrations in the affected area. This mitigation of odor also reduced corrosive damage. Both regions deployed Pyure’s controlled systems, which use sensors to measure specific parameters, allowing the units to start and stop hydroxyl production, ensuring optimized equipment lifespan and energy efficiency.

Benefits to Customers

Pyure’s hydroxyl-generating technology provided several critical benefits to the City of Sarnia and the Courtice region:

Effective Odor Elimination: The most immediate impact was the elimination of odors, which directly addressed complaints from nearby residents and improved the quality of life in surrounding areas.

Infrastructure Longevity: By reducing corrosive contamination, the lifespan of the facilities’ infrastructure was extended, resulting in long-term cost savings and operational efficiencies.

Energy Efficiency: The controlled systems optimize energy usage, contributing to sustainable operations.

Small Footprint and Cost-Effectiveness: Pyure’s system has a small footprint and lower costs compared to traditional wastewater H2S management solutions, making it a sustainable and effective option for wastewater treatment facilities.


Implementing Pyure’s hydroxyl-generating technology has demonstrated remarkable efficacy in reducing hydrogen sulfide emissions in wastewater treatment facilities. The success stories from the City of Sarnia and the Courtice WPCP highlight the technology’s ability to mitigate odors and corrosive contamination effectively.

The immediate benefits of odor elimination and improved community well-being, combined with the long-term advantages of extended infrastructure lifespan and operational efficiencies, result in an impressive return on investment (ROI) for facilities adopting this solution. With its small footprint and cost-effectiveness compared to traditional methods, Pyure’s technology offers a highly efficient and sustainable approach to managing hydrogen sulfide emissions in wastewater treatment facilities.
