Water and Wastewater Disinfection
Course Pack: UV Disinfection Systems and Chlorine Alternatives
UV, How Does It Differ?
Course Description
This module explores UV water disinfection methods and compares them with traditional chlorine water disinfection systems used in water and wastewater treatment. Learners will gain a thorough understanding of UV technology, including system designs, components, performance characteristics, and operational requirements, while examining how UV disinfection differs from chlorine-based treatment in effectiveness, maintenance, and long-term operation.
The course covers essential topics such as UV lamp technologies, fouling prevention, cleaning procedures, routine maintenance, and electrical safety practices that support reliable system performance. Participants will also evaluate the advantages and limitations of UV water disinfection and chlorine water disinfection, including pathogen inactivation, chemical handling requirements, residual protection, operating costs, and regulatory considerations. Through practical examples and real-world applications, learners will develop the knowledge needed to assess, operate, and optimize water disinfection systems while selecting the most appropriate treatment method for specific water quality and operational goals.
