Course contents:


Cold and temperate climates have special challenges when it comes to the management of water, water supply and wastewater treatment. Some of the most pristine environments are located in colder climates and the pollution of water by emerging contaminents, in addition to the nutrients, is an increasing challenge. Most treatment processes are temperature dependent, requiring additional volume and time due to the slowing down of conventional processes at lower temperatures. Water distribution and sewer systems need special care to minimise operational problems during winters and snow melting periods. Climate change often negatively impacts these conditions further.  

Course contents:

Lectures on: Water quality status, Water resources management, Water treatment, Wastewater treatment related to Cold Climates - including arctic and tempered climates, and impact of climate change.

Project report/scientific writing.

Excursions: to water and wastewater treatment plants focusing on challenges and solution in cold climates.  

Learning outcome:

Knowledge: students will have an extended understanding of cold climate conditions related  pollution states and management, treatment and operational aspects of treatment systems.

Professional skills: Students shall be able to make conceptual designs for water supply and wastewater treatment systems addressing the challenges in cold climates. They shall be able to carry out a literature review using modern scientific databases and the internet and to prepare a well-structured project report.

General competence: students shall have an extended understanding of the pollution trends in cold climates and specialised techniques to manage challenges related to water supply and wastewater treatment processes. They will be able to identify the advantages/weaknesses in current systems and propose improvements based on modern practices.

Learning activities:
(1) Lectures (2) analytical work in small teams, (3) excursion to the treatment plant(s) to learn how the unit processes are integrated and their operational challenges. (4) instructions and hands-on practice in the usage of scientific databases and reporting. 
Teaching support:
By email or pre-agreed meetings with lecturers
