Advanced Water and Wastewater Engineering (5 cr)

Objectives (course unit)

After completing this course student knows about the major physical, chemical and biological water and wastewater treatment units, such as sedimentation, filtration, coagulation/flocculation, activated sludge, N and P removal, membrane processes, ion exchange, advanced oxidation processes. He/she can perform mass balance calculations related to the units. Knows various natural wastewater treatment systems and the alternative wastewater management options. Can perform simple design of a water/wastewater treatment system for a specific situation.

Content (course unit)

Physical, chemical, and biological unit operations used in water and wastewater treatment, drinking water production, wastewater treatment, and sludge processing, laboratory exercises: activated sludge analysis, activated sludge process, coagulation and flocculation.

Prerequisites (course unit)

You will be handling real activated sludge during the course, due to which you should be up to date with the Tetanus vaccination before the laboratories.

This course is primarily aimed for the IDEE students and Double Degree students. Before taking this course you should have the Water and Sanitation course and all basic chemistry courses done. Exchange students planning to take the course, has to have experience and training in working in laboratory and should have an introductory water treatment and chemistry courses done before taking this course. If you are an exchange student and you do not have studies the aforementioned courses, you are advised to take Water and Sanitation course instead of this course.

Exam schedules

Exam at the end of the course.

Evaluation methods and criteria

The course consists of lectures and discussions, exercises, field excursion of which students write report, compulsory laboratory exercise (follow up of a pilot wastewater treatment plant during a study-period: periodical sampling, sample analyses) and exam. The course grade is formed taking in consideration the achievments from assignment and the exam, quality of laboratory report and activity and interest shown throughout the course.

Assessment scale

0-5

Teaching methods

Teach-in, field excursion, assignments,laboratory work, group work, exam

Learning materials

All lecture materials and laboratory instructions are available in Tabula. In addition, there are several good sources available for learning more about the water and wastewater engineering. One very thorough one is a book by George Tchobanoglous (1987). We recommend you to use e-books available in TAMK library, for example a book by Stephenson and Stuetz (2009) is a good source and can be accessed as an e-book.

Assessment criteria - fail (0) (Not in use, Look at the Assessment criteria above)

Student participated in the laboratory exercises and the exam. Overall the achieved competence is insufficient.
This means that
-some of the assignments were done acceptably
-the student is not familiar with the basic concepts discussed during the course
-can perform the laboratory measurements and experiments under supervision
-has no basic skills in reporting the results of the measurements and experiments
-seldom and inactive participation in the lectures

Assessment criteria - satisfactory (1-2) (Not in use, Look at the Assessment criteria above)

Student participated in the laboratory exercises and the exam. Overall the achieved competence is sufficient but narrow.
This means that
-some of the assignments were done acceptably
-the student is familiar with the basic concepts discussed during the course but often makes mistakes when applying them
-can perform the laboratory measurements and experiments under supervision
-has basic skills in reporting the results of the measurements and experiments
-seldom and inactive participation in the lectures

Assessment criteria - good (3-4) (Not in use, Look at the Assessment criteria above)

Student participated in the laboratory exercises and the exam. Overall the achieved competence is structural. This means that:
-most of the assignments were done and accepted
-exam shows that the student is familiar with the concepts discussed during the course and can apply them in most of the situations
-is fluent in the basic concepts and phenomena related to the subjects discussed during the course
-can solve model exercise and new exercises correctly
-can perform laboratory measurements and experiments independently
-the reporting of the laboratory results shows that the student attends to apply the theoretical knowledge in explaining the results
-student is clearly motivated and interested in the subjects discussed

Assessment criteria - excellent (5) (Not in use, Look at the Assessment criteria above)

Student participated in the laboratory exercises and the exam. Overall the achieved competence is wide. This means that:
-the assignments were done excellently
-student is fluent in the basic concepts and phenomena related to the subjects discussed during the course
-can solve model exercise and new exercises correctly, shows creativity in solving tasks
- can perform simple laboratory measurements and experiments independently
-the reporting of the laboratory results shows that the student can apply the theoretical knowledge in explaining the results
-student is clearly motivated and interested in the subjects discussed, eventually brings up new subject of interest
