The city of Maryville, Missouri, is making waves with its ambitious plan to overhaul its water treatment system. With a new $50 million facility planned at Mozingo Lake, this project is set to be the first in Missouri to implement ozone and biofiltration technology. At Oxidation Technologies, we’re excited to see ozone play a critical role in ensuring clean, high-quality drinking water for the community.
Why the Change?
Maryville’s current water treatment plant, built in 1958, has been struggling with modern water quality challenges, including algae blooms and geosmin contamination. Geosmin, a compound released from dying algae, has caused significant taste and odor issues in the city’s water supply. With levels reaching 2,200 nanograms per liter in Mozingo Lake—over 100 times the detectable threshold—it became clear that a new solution was needed.
Ozone and Biofiltration: A Game-Changer
After extensive testing and collaboration with HDR and Missouri DNR, a pilot ozone and biofiltration system was launched in 2022 to determine the most effective treatment method. The results were overwhelmingly positive, proving that ozone oxidation paired with biofilters is the best way to remove contaminants and improve water quality.
How Does Ozone Improve Water Treatment?
- Powerful Oxidation: Ozone breaks down organic matter, bacteria, and viruses, making it one of the most effective disinfectants available.
- Geosmin and Toxin Removal: Unlike traditional methods, ozone effectively destroys geosmin, eliminating taste and odor issues.
- Reduced Chemical Use: By replacing chlorine-heavy treatment processes, ozone minimizes the formation of harmful disinfection byproducts.
- Enhanced Biofiltration: Ozone pre-treats the water, allowing biofilters to remove remaining organic compounds more efficiently.
A Timeline for Progress
The city has laid out an aggressive timeline to get the new treatment plant operational by August 2027. Key milestones include:
- Feb. 2025: Maryville voters decide on a $50 million bond to secure state revolving fund loans.
- Nov. 2025: Construction begins.
- Aug. 2027: The new facility goes online.
With Missouri DNR’s strong support and HDR’s extensive experience, this project is poised to set a new standard for water treatment across the state.
Ozone: The Future of Water Treatment
Maryville’s investment in ozone technology reflects a growing trend in municipal water treatment. As water quality challenges become more complex, ozone’s ability to tackle emerging contaminants makes it a critical tool for the future. At Oxidation Technologies, we’re proud to support ozone-based solutions that improve water quality while reducing reliance on harsh chemicals.
Stay tuned as this groundbreaking project develops, and let’s celebrate Maryville’s leadership in bringing cutting-edge water treatment technology to Missouri!
