Water and Wastewater Disinfection
Course Pack: Chloramination
Residual Based Measurements
Course Description
This module provides an in-depth look at residual measurements in chloraminated water systems, focusing on accurate monitoring, testing challenges, and factors that influence disinfectant stability. Learners will explore how residual measurements help operators evaluate water quality, maintain treatment effectiveness, and identify potential issues within distribution systems.
The course examines key topics such as nitrification indicators, microbial impacts, residual decay, chemical balance, and corrective actions used to maintain reliable disinfection performance. Participants will gain a better understanding of how operational conditions affect residual levels and how proper monitoring practices support effective water treatment residual measurements. Through practical examples and system considerations, operators will learn strategies for improving measurement accuracy, maintaining disinfectant control, and optimizing chloraminated system performance.
Learning Objectives
1) Measure chlorine/chloramine residuals accurately
