The aim of the course is to provide participants with

  1. an overview of different types of constructed wetland systems, their applicability and their limitations
  2. a thorough understanding of the processes of importance for the transformation and removal of nutrients and various pollutants in wetlands,
  3. the capability to prepare draft designs of constructed wetland systems for specific application using commonly accepted design tools
  4.  an overview of current research needs, methodologies and options.

Learning outcomes and competences

At the end of the course the participants will be able to:

  1. characterize biogeochemical processes of importance for nutrient removal in wetlands,
  2. describe the functional role of different types of wetland plants in wetlands,
  3. describe different types of constructed wetland systems, their applicability and limitations,
  4. characterize the hydraulics of constructed wetland systems
  5. characterize pollutant removal pathways and removal kinetics
  6. prepare initial draft designs of constructed wetland systems for wastewater treatment

The course will provide an overview of the ecology of freshwater wetlands including hydrology, wetland soil biogeochemistry, and wetland plant ecophysiology. The processes responsible for the transformation of organic matter, nutrients and micropollutants such as pharmaceuticals and personal care products in the wetland environment will be described. The state-of-the-art in design techniques based on hydraulics and pollutant removal models in different types of constructed wetland systems will be demonstrated. Practical design guidelines and management aspects such as system layout, compartmentalization, substrate selection, inlet and outlet structures, plant selection and planting will be presented. The use of constructed wetland for the treatment of different types of wastewaters, such as domestic and different types of industrial wastewaters, will be demonstrated through case-stories from around the World, including systems established in different climate (cold-temperate areas, sub-tropics and tropics, arid and semiarid areas).

Teaching curriculum
Teaching will be mainly through lectures. However, theoretical exercises and plenary discussions will also be arranged where participants will be required to prepare designs of wetland systems for the treatment of various types of contaminated water based on case-stories, and using existing design tools. Systems dealt with include surface flow and subsurface flow treatment wetlands, vertical flow systems, intensified constructed wetland systems, evaporative zero-discharge systems, free-floating macrophyte treatment systems, sludge treatment reed beds, stormwater treatment systems, and in-catchment agricultural runoff treatment systems. Excursions to full-scale constructed wetland systems will be arranged.

Teaching will be in English

Location and time
The course will be held at the Mols Laboratory in the Mols Bjerge National park.

Arrival the 18th June in the afternoon; departure the 24th of June after breakfast.

Pass/fail on the basis of satisfactory participation in the course and on the written report that has to be prepared and submitted one week after the course. Prior to the course, each participant will be asked to prepare a poster addressing the main parts of their own research.

Target group
The target group for the course is young researchers and PhD-students with projects related to processes in aquatic and wetland environments addressing environmental issues and ecological engineering options. First priority is given to GSST PhD-students.
