ECTS
5
Prerequisites
Main purpose
- To create an understanding of the activated sludge process and advanced wastewater treatment.
- Through information retrieval, discussions, presentations, and group works to provide the student with knowledge current topics related to biological treatment of wastewater.
Knowledge
- Concepts and assessment methods involved in providing basic understanding of activated sludge process and the possibility of achieving biological cleaning of wastewater.
- Usage and application of design models and constructions.
- Knowledge of the impact on the biological process from outside factors.
- Ability to find needed constructions and process to create the wanted level of treatment.
Skills
- Able to calculate an activated sludge process tank with removal of organic matter, nitrogen and phosphor.
- Standards for sludge characterization
- Analytical methods in identifying needed treatment of the wastewater.
- Principles and application of advanced as well as simple treatment methods
- Functioning skills necessary to get a satisfying profit from working in groups
Competences
- Characterize different treatment methods with respect to physical, chemical and microbiological parameters
- Evaluate wastewater data and from this being able to describe a suitable cleaning method
- Present results to the actual client in a clear and simplified way
- Analyze a situation with inefficient treatment and find a way of improving this using learned treatment methods and skills.
Topics
- Dimensioning and designing of a wastewater plant with nitrification.
- Dimensioning and designing of a wastewater plant with denitrification
- Dimensioning and designing of a wastewater plant with biological phosphor removal.
- Knowledge of oxygen consumption and aeration systems.
- Knowledge of simple types of green wastewater treatment plants.
- Understand principles of optimized constructions concerning energy consumption and impact from weather conditions.
Teaching methods and study activities
Lectures followed up by assignments, individual information retrieval, data analysis, report writing in groups, discussions in groups assisted by the lecturer, presentations, self-study, homework assignments.
137,5 hours of work for the student.
Study Activity Model
According to the Study Activity Model, the workload is divided as follows:
Category 1, Initiated by the lecturer with the participation of lecturer and students: 40 hours - 29%
Category 2: Initiated by lecturer with participation of students: 40 hours – 29%
Category 3: Initiated by students with participation of students: 37.5 hours – 27 %
Category 4: Initiated by students with the participation of lecturer and students: 20 hours – 15%
