COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Recognize and explain tertiary treatment processes commonly used to treat domestic and

    industrial waste, including effluent and solids disposal methods.

2.  Explain the laws and penalties governing wastewater treatment operations that apply to

    operators and facilities.

3.  Prepare for the SWRCB (State Water Resources Control Board) Wastewater Operator

    Certification Grade 2 exam.
