Average Course Rating

(4.48)

This course focuses on the fundamentals and applications of aerobic and anaerobic biological unit processes for the treatment of municipal wastewater, resource recovery from waste streams, and biological processes for drinking water production. The principles of activated sludge treatment, suspended and biofilm growth, biological nutrient removal, anaerobic treatment, solids handling and treatment, land treatment, and nutrient removal are presented. This course uses concepts from microbiology and the basic principles of stoichiometry, energetics, and microbial kinetics to support the design of biological unit processes. This course will meet with EN.570.646.

The best aspect of this course was the problems that were broken down into understandable segments for the benefit of the students. The course covered basic processes regarding wastewater treatment and gave students a comprehensive understanding of the operation procedure in a wastewater treatment plant. Some students felt the assignments were purposeful y excessive and too difficult to complete. One suggestion included shortening the study guides. Another suggestion was not making the final exam 135 cumulative. Prospective students should know that background knowledge in physiochemical treatment methods is beneficial.

The best aspects of this course were the well-structured lectures, the balance between technical work and design work, and the field trip to the waste water treatment plant. Many students cited the time needed to complete homework and the relatively low weight it was given as the worst aspect of the course. To improve the course, shorter homework with better examples or references and more group work were suggested. Prospective students should know that taking Engineering Microbiology first is quite beneficial, and this course has a fairly heavy workload.

Students enjoyed the interesting readings and intimate class size which facilitated relevant group discussion. Students appreciated gaining perspective from other students from diverse majors. Students felt that the readings were difficult and time consuming. Suggestions for improvement included having shorter class periods, assigned readings with a clearer perspective, and writing assignments due the day before so students are able to read classmates’ perspectives. Prospective students are encouraged to prepare for class discussion by thoroughly reading the assigned articles and taking notes on questions and ideas surrounding course topics.
