Webinar | Chlorine Disinfection Control - DPD vs Amp

Chlorine is a powerful disinfectant that has played a critical role in municipal water treatment for over a century and is one of the most important tools for protecting public health. However, ensuring effective disinfection without creating harmful by-products requires careful monitoring and control.

Watch a technical deep dive into chlorine disinfection, exploring the chemistry, monitoring requirements, and sensor technologies that drive reliable water quality. This session will compare DPD-based analyzers and amperometric sensors, helping you understand when and why to measure free vs. total chlorine in both drinking water and wastewater applications.

What You’ll Learn:

• The role of chlorine in disinfection and factors affecting its behavior

• Differences between free and total chlorine—and when each should be measured

• Principles, strengths, and limitations of DPD and amperometric technologies

• Guidance for selecting the right monitoring approach for your facility

• Best practices for chlorine dosing, calibration, and maintenance

Who Should Watch:

Operators, engineers, and water quality professionals are responsible for monitoring and complying with disinfection standards in drinking water and wastewater systems.

Learning Outcomes:

By the end of this webinar, you’ll be able to:

• Understand free vs. total chlorine differences and when to monitor each parameter

• Compare DPD and amperometric systems, recognizing appropriate use cases and considerations

• Apply monitoring and dosing strategies for improved process control in drinking water and wastewater applications.
