Objectives: |
1. To develop a
theoretical basis for determining the composition of natural water and the
behavior of chemical processes used in the treatment of waters and
wastewaters including consideration of variables that affect the above
systems; |
|
|
2. To show how the
principles can be applied to understanding the chemistry of natural waters
and treatment systems; |
|
|
3. To provide the student
with the background necessary to use the current prevailing approach to water
chemistry as presented by Stumm & Morgan, and many others. |
|
Outcomes: |
1. Ability to interpret
and predict acid/base behavior, and metal-ligand complexation of natural
waters and wastewaters. |
|
|
2. Ability to interpret
oxidation/reduction reactions and precipitation/dissolution of minerals and
amorphous solids in waters, and predict equilibrium tendencies |
|
|
3. Ability to solve
problems in groups and present the solutions orally |
|
|
4. Ability to use current
software for solving water chemistry problems |
|
|
5. Ability to understand
and communicate new developments in
water chemistry |
|
Outcome Measures |
1. Weekly homework
problems on principles covered in class |
|
and Assessment: |
2. Two 2-hr long exams of
a comprehensive nature testing comprehension from homeworks, class lectures,
and readings. |
|
|
3. Miscellaneous computer
assignments and review papers testing the student’s ability to extend general
course principles to other types of problems |
|
|
4. In-class evaluation by
oral participation and problem-solving. |
