Detailed study of filtration, disinfection, and membrane technologies for producing high-quality drinking water.
About this course
WATR 2190 Advanced Water Treatment Processes moves beyond basic treatment to examine the technologies required for producing safe, high-quality drinking water. You will explore the chemical and physical principles behind filtration, disinfection, and membrane separation. The course covers the operation of rapid sand filters, activated carbon adsorption, and advanced oxidation processes.
Membrane technologies, including reverse osmosis and ultrafiltration, are a major focus. You will learn how to select the right membrane process for specific contaminant profiles and how to manage issues like fouling and concentrate disposal. The course also covers modern disinfection methods, comparing chlorine-based treatments with ultraviolet and ozone systems.
Who takes this course
This course is required for students in the Water & Wastewater Technician program. It is typically offered in the third term of the program, after students have completed their foundational chemistry and water cycle studies.
