Course Objective: To teach learners about treatment processes targeted for removal of specific contaminants or other undesirable substances from drinking water with main focus on iron and manganese removal and water softening.
This course, part of the Water Treatment Fundamentals bundle, focuses on specific water treatment processes. 4 Contact Hours (or 0.4 CEUs) will be granted upon completion of this course.
Disclosure: None
