Overview
This introductory course for industrial and municipal wastewater treatment processes will cover principles that wastewater operators need to be successful at their jobs. The course will be packed with knowledge starting with the Code of Federal Regulations and ISO standards for protecting the environment. Discussions on how wastewater treatment processes differ from industrial to municipal, what equipment is needed for successful treatment of wastewater, and how to test wastewater for treatment efficiencies and safety will be highlighted. Math, as always, plays an important role in successful wastewater treatment. Basic math formulas needed in wastewater treatment will be reviewed. Additionally, the course will explore the chemicals needed for wastewater treatment and how to determine their dosing using bench testing. Upon completion of this course, attendees will have a basic understanding of the principles of wastewater treatment to carry them forward.
