Content and learning outcomes

Course contents

Microorganisms can often, in an economical and efficient manner, purify water from impurities like organic material, nourishment substances and poison.  We study biological purification systems and their active key organisms in this course.  We also go through the techniques used to control their small organisms. 

The course consists of ten three-hour seminars where you will work in groups and listen to a shorter presentation from experts in the area.  In every seminar, a section from the book will be read in advance so that it may be discussed during the seminar. 

The labs correspond to 2 credit points.  The lab schedule will be posted at the start of the course.  You will, among other things, analyze microbiological processes in sewage water and isolate and identify bacteria in active sludge.

Intended learning outcomes

In order to pass the course, the student must:

  • participate actively in all of the seminars (or if the student can’t attend, there is the possibility to write a short paper on the seminar’s topic)
  • fulfill the lab course in a satisfactory manner
  • write a paper within one of the topic areas which is mentioned during the course.  This paper will be critiqued and opposed by one of your course mate
  • participate in the opposition and critique of another course mate
