CEE
690K ‑ ENVIRONMENTAL REACTION KINETICS
Spring Semester 2008
TuTh 1:00 (Mrst 15)
Course Description: CEE
690K: Environmental Reaction Kinetics. Environmental Engineers are increasingly
called upon to analyze the speed of pollutant conversion in chemical and
biological systems. These may be engineered systems such as water and
wastewater treatment plants, or natural systems, such as lakes and aquifers
receiving industrial pollution. This course examines the rates and kinetics of
a range of chemical and biological systems important to Environmental
Engineers. These systems are limited to the aqueous phase at atmospheric
pressure and near ambient temperature. The fundamentals of kinetic theory are
briefly covered. Mathematic simulation of kinetic systems and analysis of
kinetic data are examined. Several case studies of importance in Environmental
Engineering are explored in detail. Prerequisites are CEE 370, Chem 111, Chem
112 and CEE 680 or equivalent.

Objectives: 1. To become familiar with the fundamentals
of chemical kinetics.
2. To learn how to design
kinetic studies and interpret the results.
3. To understand the
theoretical impacts of changes in physical, chemical and biochemical conditions
on the anticipated rate of environmental processes, and
4. To gain detailed
understanding of the kinetics of a few selected processes of significance to
Environmental Engineers.
Prerequisites by Topic:
1. Basic understanding of
environmental engineering and the significance of environmental parameters
(e.g., CEE 370).
2. Knowledge of chemical equilibria in natural
waters (e.g., CE 680).
3. Understanding of chemical and biological systems
in Environmental Engineering (e.g,. CEE 371)
Goals: |
1. To provide a fundamental understanding of the means by which kinetic models are formulated so that the students are able to adapt existing models to new situations. |
|
2. To provide the students with some direct exposure to kinetic models currently used in environmental engineering practice. This will equip them with the knowledge to apply such models to help with design and operation of treatment systems |
|
3. To instruct as to how kinetic data can be analyzed and interpreted |
|
4. To show how kinetic models may be calibrated, verified, and applied to environmental engineering problems. |
|
5. To further develop the students’ skills at working in teams, and presenting results in the form of written engineering reports and oral presentations to clients or to the public. |
|
6. To acquaint the student with current issues in environmental kinetics; and to make them aware of the technical, political, ethical and sociological components of these issues. |
