The aim of the course is to build knowledge on the principles of wastewater treatment technologies. Wastewater characterization methods and the main wastewater treatment technologies based on chemical, physicochemical and biological processes are explained.

Written examination: 10 questions, 10 points each

Improvement of the grades B-E is allowed by repeating the exam with a prior arrangement with the teachers. The most recent exam result is always valid.
