Water and Wastewater Disinfection
Course Pack: Chloramination
A Continued Look at the Use of Chloramination
Course Description
This module provides an advanced look at chloramination practices in water treatment systems, focusing on maintaining effective chloramine formation, stability, and disinfection performance. Learners will explore key aspects of chloramination, including chemical ratios, residual species measurement, and strategies for optimizing chloramine systems.
The course covers important operational considerations such as managing raw-water ammonia, applying ammonia removal protocols, controlling chloramine residuals, and reducing free ammonia levels to achieve improved system performance. Participants will gain practical knowledge of how proper monitoring, adjustment, and maintenance practices support reliable chloramination in water treatment. Through applied examples and operational insights, operators will learn how to optimize chloramine processes, improve water quality, and maintain effective disinfectant control across distribution systems.
