About this course
The focus of this course is on water and wastewater treatment technologies.
Students will learn about processes and technologies for designing and upgrading water and wastewater treatment plants. The capstone assignment is to design water and wastewater treatment plants upgrades based on two respective case studies.
The goal of this course is to enable students
- to justify the selection of processes and
- to propose technologies of water and wastewater treatment for design and upgrade of treatment plants.
Knowledge of processes used for water and wastewater treatment and the ability to propose respective technologies will be the basis for evaluating student performance in the course.
Topics covered in the course:
- Introduction to water and wastewater treatment technology
- From water crisis to a water-wise world
- Water supply and wastewater management in Norway and Europe
- Physical and chemical quality of water and wastewater characteristics
- Microbiological quality of water
- Micropollutants and emerging water quality challenges
- Coagulation-flocculation and chemical precipitation
- Gravity separation
- Depth filtration
- Micro- and ultrafiltration
- Flotation
- Adsorption
- Ion exchange
- Reverse osmosis and nanofiltration
- Disinfection
- Conventional and advanced oxidation
- Biological treatment
- Aeration and stripping
- Emerging processes
- Principles of control and automation
- Correction of aggressivity and remineralisation
- Residuals management and sludge treatment
- Future challenges and opportunities
Learning outcome
At the end of this course, students will know:
- global context and status of the water sector
- essential water quality indicators and wastewater characteristics
- common physical, chemical, physical-chemical, and biological processes applied in the water sector
- examples of water and wastewater treatment technologies
and will be able to
- characterise the source water quality and wastewater characteristics and define treated water quality goals and standards
- perform predesign studies, including process selection and development of design criteria
- propose design alternatives for the selected processes
This course is offered as synchronous: it runs in real-time with students and instructors attending together.
The course contains technical lectures, readings, technical excursions, keynotes and workshops involving serious games and digital collaboration tools.
All instructors offer individual or group consultations in-person or online by appointment via email.
Students with special needs are entitled to special arrangements for their exams.
Please contact the special needs office for more information.
- A basic course in chemistry or water chemistry, for example KJM100 (Chemistry) or KJM220 (Water Chemistry).
- A basic course in microbiology is recommended, for example equivalent to BIO130 Microbiology
Combined assessment, based on:
- Capstone project (term paper), which counts for 60 %
- Digital campus-based written exam (3 hours) during the exam period, which counts for 40 %. The exam can include both multiple-choice questions and other questions. Aids code B1 (distributed calculator, no other aids).
Grading rule: A - F
Term paper Grading: Letter grades Written exam Grading: Letter grades Permitted aids: B1 Calculator handed out, no other aids- The external and internal examiner jointly prepare the exam questions and the grading guide. The external examiner reviews the internal examiner's assessment of a random sample of candidates as a calibration at certain intervals according to the faculty's guidelines for exam grading.
- Two field trips (technical excursions) and the capstone project (term paper) are mandatory. The capstone project counts towards the final grade.
- The course is designed for master's students in the Water and environmental engineering program as well as other water-related programs (environmental science, food sciences, etc).
The organized teaching time includes:
- Lectures: Four hours per week
- Exercise and supervision sessions: Two hours per week
- Field trips: Two half days
- REALFAG (special requirements in science)
