Water and Wastewater Treatment MLJ610

By completion of the course the student should know fundamental principles for treatment methods for potable water and municipal wastewater. This includes quantiotative analysis based on mass and energy balances for design and operation of mechanical, chemical and biological wastewater treatment unit processes. Students will also be able to evaluate sound applications and processing of produced solids, and know the principles for solids management in the circular bioeconomy.

Learning outcome
The students should know the basic principles of mechanical, chemical and biological methods for treatment of drinking and different types of wastewater. The student is able to do laboratory analyses of the most common parameters associated with wastewater treatment (SS, BOD, N, P, color, total and coliform bacteria) and perform simple laboratory tests for characterization and treatment evaluation of different wastewater methods. Furthermore, students will be able to design and dimension wastewater treatment unit processes based on mass- and energy balances, including steady state modelling. This includes all classes of sedimentation, gas absorption, coagulation and flocculation, disinfection, advanced oxidation, biological treatment by suspended and biofilm biomass, aerobic and anaerobic sludge treatment. Students will also be able to evaluate sound applications and processing of produced solids, and know the principles for solids management in the circular bioeconomy.
Fundamental and advanced knowledge of mechanisms for biological, chemical and mechanical methods for treatment of potable water and municipal wastewater is covered. Through lectures, coursework and laboratory exercises students will gain knowledge and competences to be used for design calculations and operational optimization of primary, secondary, tertiary and advanced tertiary treatment processes based on first principles.
Required prerequisite knowledge
Recommended prerequisites
MLJ530 Environmental Process Analysis
MLJ530 Environmental Process Analysis or similar course, and basic chemistry as required for admission to MSc Environmental Engineering

Written midterm, lab-assignments and a final written exam

Form of assessment Weight Duration Marks Aid
Written midterm 25/100 2 Hours A - F Approved, basic calculator Dictionary
Lab-assignments 35/100 A - F
Written exam 40/100 4 Hours A - F Dictionary Valid calculator

Course teacher sets final mark: Written mid-term exam counts 25% and written final exam counts 40%. Laboratory exercises count 35%. Both laboratory reports, written mid-term exam and written final exam must be passed to have a final grade.If the laboratory exercises or mid term is evaluated to a non-passing grade, the student can re-sit these the next semester the course is taught. Retake exam (final exam only) follow the faculty's ordinary schedule.

Coursework requirements

Completion of mandatory lab assignments are to be made at the times and in the groups that are assigned and published on Canvas. Absence due to illness or for other reasons must be communicated to the laboratory personnel as soon as possible. One cannot expect that provisions for completion of the lab assignments at other times can be made, unless prior arrangements with the laboratory personnel have been agreed.

Failure to complete the assigned labs on time or not having them approved will result in barring from taking the final course exam.
