Water and Wastewater Disinfection
Course Pack: Dechlorination & Advanced Oxidation
Measuring Delivery Doses
Course Description
This module provides Measuring Delivery Doses training, equipping operators with the skills needed to perform accurate chemical-dose calculations, evaluate deterioration rates, and understand the equipment used to deliver hypochlorite and other dechlorination chemicals. Learners explore pump sizing, injection-point selection, and mixing effectiveness to ensure reliable chemical performance. Through this Measuring Delivery Doses training, operators gain practical troubleshooting skills for identifying and resolving common feed-system issues, including flow interruptions, dosing inconsistencies, and pump performance problems.
Learning Objectives
1) Perform dose calculations for chlorine/dechlorination
2) Interpret deterioration rates
3) Select proper dosing hardware
4) Evaluate mixing and injection locations
5) Troubleshoot pump and flow issues
Agenda
1) Principles of chemical dose calculation and their application to treatment control
2) Estimation of oxidant or disinfectant deterioration rates to support accurate dosing
3) Overview of flow‑control hardware and operational considerations for feed systems
4) Selection of appropriate injection points to ensure effective mixing and treatment performance
5) Pump sizing, routine maintenance practices, and troubleshooting of common feed‑system issues
Target audience
