This online course deals with the basic principles of wastewater treatment in constructed wetlands and enables the participants at the end of the course to make a proper design of their own wetland system for wastewater treatment.
Participants complete the course in a period of about four months (16 weeks) with a workload of 140 hours. A participant is expected to spend about 8 hours per week on reading, discussion and assignments. The course is sub-divided into 3 modules and a written assignment.
Within the course, each module starts and ends on a specified day. Generally, a subject takes 3 weeks. Within this period, the participant is free to study in his or her own time. Questions with regard to the subject can be posted on the discussion forum, eliciting responses from fellow participants. The teachers also regularly comment on the questions posted on this forum.
Each subject ends with assignments for which participants have to use their newly acquired knowledge and interact with the teacher and the other participants using the discussion platform of the online learning environment. Participation will be assessed on the basis of tutor assignments, contribution to the online discussion assignments and the final paper. Upon successful completion of the course, participants will receive a Course Certificate issued by IHE Delft.
