ECTS

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.
