Prerequisite course: 014322
Credit points: 2.5Weekly learning duration: Lecture – 2 h; Laboratory – 2 h


Course description and objectives:
The goal of the course is to teach basic techniques of laboratory tests of water and wastewater treatment engineering-related issues. The lab exercises simulate water and wastewater treatment processes. The laboratory work includes several selected tests and experiments of chemical, physical and physico-chemical methods which related to water quality control processes, water sources, and treatment processes of water, wastewater and sludges (biosolids).


Learning achievements
By successful graduation students will master basic techniques of laboratory tests related to water, wastewater and treatment of both, and gain practical experience (in laboratory scale) of several treatment processes of water and wastewater.


Necessary equipment:

Each student should bring along at least:
• Laboratory notebook (hard cover) with student name on it. EVERYTHING you do in the lab should be written in the notebook (we reserve the right to go over your notebooks).
• Attach the lab safety instructions to the first page of the notebook.
• Pen, pencil, eraser, small ruler, and calculator.
• Permanent marker
• Safety equipment (will be provided)


Student evaluation and grade composition
1. Attendance is mandatory (lectures, lab, quizzes)
1.1 Absence from lab or quiz –justified reason (e.g. IDF reserve service) and authorized by course professor. New date for supplementary lab or quiz must be set immediately .
1.2 Unjustified absence – Zero (0) grade would be given for lab/quiz.
1.3 You have to be on time – Being late more than 10 minutes – Attendance to the lab will not be permitted and 0 will be given on the quiz and on the lab report.
2. Quizzes – At the beginning of each lab session, a short quiz will be given (closed notebooks, 10 minutes) on the subjects that will be studied in the lab (up to 10 quizzes).
3. Reports – reports should be submitted up to two weeks from completion of the lab.
• Report should be submitted in pairs.
• Submission should follow the given instructions.
• Report should be submitted through the Moodle.
• Points will be deducted for late submissions (2 points per day)
4. Grade composition
Laboratory reports 70%
Quizzes 30% – n-1 best grades will be considered (n – number of quizzes)

Academic integrity
Group learning and discussion of the course materials given in the lectures and lab exercise is encouraged.
Nevertheless, we would like to emphasize – Copying laboratory reports or quizzes is not “group learning” but CHEATING. If caught cheating – 0 will be given and the mark will be included in the final grade
