Water and Wastewater Disinfection
Course Pack: Chlorine Dioxide Disinfection and Monitoring
Let’s Dig Deeper! (ClO2)
Course Description
This module explores advanced chlorine dioxide applications in water treatment, focusing on the performance benefits, operational considerations, and practical uses of chlorine dioxide (ClO₂) as an effective disinfection and oxidation solution. Learners will examine how chlorine dioxide applications improve disinfection efficiency, enhance taste and odor control, and support biofilm management in water systems.
The course covers real-world applications of chlorine dioxide, including treatment challenges, operational limitations, dosing considerations, and system performance factors. Participants will also compare chlorine dioxide with other oxidants and disinfection methods to understand its advantages, effectiveness, and role in modern water treatment operations. Through practical examples and industry-focused insights, operators will gain the knowledge needed to evaluate and optimize chlorine dioxide water treatment applications for safe, reliable, and efficient disinfection performance.
