Water and Wastewater Disinfection
Course Pack: Sodium Hypochlorite
Let the Secrets Begin
Course Description
This module introduces the operational use of hypochlorite disinfectants,
emphasizing chemical properties, stability, and safety requirements across storage and feed
systems. Learners examine product-quality variability, temperature and strength degradation,
and best practices for compatible pumps, materials, and equipment. The course supports safe,
consistent, and compliant hypochlorite application in water and wastewater treatment
processes.
Learning Objectives
1) Explain hypochlorite chemistry and disinfection principles
2) Identify safety risks and mitigation practices when handling hypochlorites
3) Recognize challenges from inconsistent retail hypochlorite products
4) Evaluate delivery quality including temperature and storage impacts
5) Apply best practices for pumps, hardware, and system compatibility
Agenda
