Water and Wastewater Disinfection
Course Pack: Dechlorination & Advanced Oxidation
High vs. Low Strength Hypochlorite
Course Description
This module provides High vs Low Strength Hypochlorite training, comparing the characteristics, applications, and handling requirements of high- and low-strength hypochlorite solutions. Learners explore dechlorination methods using sulfite, vitamin C, and peroxide, along with refractometry techniques for verifying chemical strength. Through this High vs Low Strength Hypochlorite training, operators gain practical knowledge of method selection, safety considerations, combustion-hazard prevention, spill response, and monitoring practices that support effective and compliant chemical management.
Learning Objectives
1) Compare various dechlorination chemicals
2) Use refractometry for strength measurement
3) Identify spontaneous combustion risks
4) Evaluate pros/cons of methods
5) Apply safe spill management procedures
Agenda
1) Overview of sulfite, vitamin C, and peroxide as dechlorination agents and their treatment roles
2) Fundamental refractometry principles for monitoring solution strength and process control
3) Recognition and prevention of combustion hazards associated with oxidizing and reducing agents
4) Criteria for selecting appropriate dechlorination and measurement methods based on system needs
5) Safety practices for spill response and application of operational scenarios to reinforce compliant procedures
Target audience
Operators performing dechlorination, hypochlorite handling, or strength-verification testing.
