COURSE OVERVIEW

This practical and highly-interactive course includes various practical sessions and exercises. Theory learnt will be applied using our state-of-the-art simulators. 

 

This course is designed to provide participants with a detailed and up-to-date overview of Chlorine Dioxide (ClO₂) Disinfection Systems. It covers the water disinfection technologies, chlorine dioxide (ClO₂) basics and mechanism of disinfection by ClO₂; the stability under various pH and temperature conditions, reactions with organic and inorganic substances, formation and control of by-products and influence of water quality on reactivity; the acceptable limits in drinking water, health effects of ClO₂ and byproducts, environmental impact of discharge and ecotoxicology and aquatic risk; the ClO₂ generation methods, ClO₂ generation equipment and technologies and storage and delivery considerations; the typical schematic of ClO₂ disinfection system, placement of sensors and injection points and design considerations; and the flow integration into water systems. 

 

Further, the course will also the sizing and dosing calculations, material selection and compatibility and online monitoring and measurement; the PLC-based dosing control, feedback and feed-forward loops, alarm systems and interlocks and integration into plant DCS/SCADA; the process optimization techniques, residual management and compliance, alarm management and safety interlocks; the proper maintenance and calibration procedures and daily operation procedures; the low ClO₂ yield or dosing errors, sensor drift and calibration issues, pipeline scaling and corrosion; and the alarms and system malfunctions. 

During this interactive course, participants will learn the root cause analysis of failures, process deviation and correction and maintenance logs and failure trends; the ClO₂ gas leak handling, chemical spill containment, system isolation protocols, emergency PPE and response kits; the operator safety and PPE requirements, training and competency development and integration with desalination and RO systems; the power plant water systems covering cooling tower disinfection, boiler feedwater applications, legionella control strategies and ClO₂ compatibility with power equipment; auditing and inspecting ClO₂ systems; and the regulations and documentation including advanced topics in ClO₂ disinfection.
