ENVL 506. Water and Wastewater Treatment Processes.                                                                                                  Fall 2002

2002-2004 Catalog Description:

Study of the fundamental principles used to treat both drinking water and wastewater.  Drinking water treatment principles include Stokes law for particle settling, theory of coagulation and flocculation, porous media filtration, and disinfection.  Principles  for wastewater treatment include reactor analyses, growth and degradation kinetics for biological oxidation processes anaerobic digestion of complex organics, and hindered and compression settling.  Three lectures.  Fall.  (Cr. 3). Prerequisite: ENGS 204.

Textbook: Unit Operations and Processes in Environmental Engineering, Reynolds and Richards, 4^th ed.      

Goal: The goal of this course is to learn, understand and be able to apply the fundamental principals and analytical tools needed to fully comprehend the major processes that are used to treat drinking water and wastewater.   The objectives that will help fulfill this goal are as follows:

Objectives:

1.      Fully understand the fundamental scientific, mathematic, and engineering principals that govern the unit processes used to treat drinking water and wastewater.

2.      Be able to apply relevant mathematical, scientific and engineering principals with regard to water and wastewater treatment processes.

3.      Be able to function in a team to solve engineering problems that are relevant to water and wastewater treatment.

4.      Be able to apply established engineering techniques and skills to the study of water and wastewater unit operations. 

5.      Be able to identify, formulate and solve engineering problems related to the design and operation of water and wastewater treatment processes.

6.      Gain an appreciation for the contemporary and regional water resource issues and the public health, political and economic factors that impact those issues.

7.      Understand the ethical and professional obligations of engineers and scientists who are instilled with the responsibility of preserving out water resources and protecting public health
