Water and Wastewater Disinfection
Course Pack: Advanced Disinfection Technologies: Chloramination, Ozone, and UV
Pros and Cons
Course Description
This module provides a detailed comparison of the pros and cons of water disinfection methods used in modern water treatment and wastewater treatment systems. Learners will explore the benefits and limitations of chlorine disinfection, chloramines, chlorine dioxide, ozone disinfection, and UV disinfection, gaining a clear understanding of how each method impacts water quality, pathogen removal, operational efficiency, and regulatory compliance.
The course covers essential water treatment disinfection concepts, including CT calculations, disinfectant dosage requirements, residual maintenance, and factors that influence disinfection effectiveness. Participants will examine the advantages and disadvantages of each technology, such as byproduct formation, chemical handling and safety concerns, monitoring requirements, maintenance needs, and overall treatment costs. The training also reviews compliance standards, performance optimization strategies, and key considerations for selecting the most effective water disinfection system for specific treatment objectives. By the end of the module, learners will have the knowledge needed to evaluate and implement appropriate water and wastewater disinfection methods that support safe, reliable, and compliant treatment operations.
