Course contents:

This course prepares graduates to apply water and wastewater treatment technologies in practice. This course forms a solid basis for the advanced course THT 310.

The course includes four study modules. The division into modules is based on the differentiation between "process" and "technology". The process produces the benefit; whereas technology provides the capability to deploy such a process and establish processes in the form of a system that is easy for operators to follow.

Module 1 introduces the subject:

  • Global status and challenges in the water sector
  • International, European, and Norwegian legislation in water supply and wastewater management
  • Water and wastewater quality aspects and chemistry

Module 2 is about processes applied in both water and wastewater treatment:

  • Physical, chemical, physical-chemical, and biological treatment processes

Modules 3 and 4 are about technologies used in water and wastewater treatment:

  • Removal of particles and phosphates
  • Natural organic matter removal
  • Removal of organic matter and nutrients
  • Membrane biological reactors
  • Removal of dissolved solids
  • Disinfection
  • Industrial wastewater treatment
  • Water-smart circular economy
  • Residuals management, biosolids processing, treatment of sludges
  • Dealing with emissions

Modules 3 and 4 include two parts of the course assignment: one on drinking water treatment and another on wastewater treatment.

In this course, you will be working on the application of the existing designs, selecting, and justifying the application of treatment processes and technological units. You will be able to follow-up one of your case-studies developed in this course (water or wastewater treatment) in the advanced course (THT 310) with detailed calculations

Learning outcome:

At the end of this course, graduates will be able to:

  • define major challenges in the water sector and possible technological solutions
  • list international, European, and Norwegian water and wastewater regulations
  • recognise water and wastewater quality parameters as well as main water and wastewater treatment processes
  • characterise water and wastewater quality
  • describe the main technologies of water and wastewater treatment
  • explain the chemistry and physics behind the main water and wastewater treatment processes
  • identify the applicability of main water and wastewater treatment technologies
  • choose applicable water and wastewater treatment technologies
  • analyse water and wastewater treatment flowsheets
  • categorise and compare unit processes
  • evaluate the efficiency of water and wastewater treatment technologies
  • synthesize water and wastewater treatment sequences
Learning activities:
Lectures. term papers, excursions to treatment facilities.
Teaching support:
Course responsible offers academic supervision during office hours, after appointment.

A basic course in chemistry, for example KJM100 (Chemistry)
Recommended prerequisites:
A basic course in microbiology is recommended, for example equivalent to BIO130 Microbiology.
Mandatory activity:
Excursions to treatment plants and term paper. Term paper shall be submitted as a written report and if needed also presented in the plenum.
3-hour written digital examination counts for 60% of the final mark. The exam may include MCQ and/or essay-type questions. The term papers will count for 40% of the final mark.
Nominal workload:
For a course of 10 credits, ca. 250 hours of work in total is normally to be expected. That means that in addition to structured teaching, ca. 6-7 hours of work must be expected per week.
Entrance requirements:
Special requirements in Science
Type of course:
Lectures: ca. 50 hours. Excursion: ca. 4 hours. Term papers.
The course is designed for Master"s students in the Water and environmental technology program, 2- year MSc program on Sustainable water and sanitation, as well as other water-related courses (food sciences, etc).
The external and internal examiner jointly prepare the exam questions and the correction manual. The external examiner reviews the internal examiner's examination results by correcting a random sample of candidate's exams as a calibration according to the Department's guidelines for examination markings.
Allowed examination aids: B1 Calculator handed out, no other aids
Examination details: Combined assessment: Letter grades
