A. Knowledge
- Ability to understand the operation and contaminant removal processes in these systems.
- Basic knowledge about the advantages and disadvantages of natural treatment in comparison with common activated sludge treatment.
- Basic knowledge about the design criteria of the different natural treatment systems.
B. Skills
- Knows the operation of the different natural treatment systems.
- Knows the legal background of application.
- Understand the processes leading to decrease contaminant concentrations during the treatment process.
- Ability to make corrections if disorder operation occurs.
C. Attitudes
- Cooperates with the teacher and fellow students in expanding the knowledge.
- Open to use the IT possibilities.
