Course Objective: To teach learners the principles and operation of individual processes of conventional drinking water treatment.
This course, part of the Water Treatment Fundamentals bundle, focuses on flash mixing, coagulation, flocculation and sedimentation. 4 Contact Hours (or 0.4 CEUs) will be granted upon completion of this course.
Disclosure: None
