                        stripping, and membrane) for water and wastewater treatment.

 

Prerequisite:   unit operations in water and wastewater treatment, calculus, water chemistry, and ordinary

                        differential equations.

Course Policy:

 

For on-campus students, homework is due by 5 pm One week after the day it was assigned unless specified otherwise. For outreach students, one extra week is given to compensate postal delivery. Homework solution will be posted on the bulletin board outside my office on the following day or mailed to you (outreach students). Late homework will NOT be graded.

 

University, college, and/or department policies will be applied.
