General Information

Main field: Water Resources Engineering Depth of study relative to the degree requirements: Second cycle, in-depth level of the course cannot be classified
Elective for: K4, MWLU1, V4-vr, W4-vr
Language of instruction: The course will be given in English

Aim

Future effluent requirements on wastewater treatment will be more stringent regarding nutrients as well as various micropollutants. At the same time there are high expectations on space- and energy efficient solutions.

The aim of the course is to:

• provide in-depth knowledge of principles and methods for mechanical, biological and chemical wastewater treatment
• provide tools to apply in selection and design of advanced wastewater treatment systems.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to suggest suitable treatment technologies for a wastewater stream with given prerquisites in terms of hydraulic loading, pollutant loading and effluent requirements.

Competences and skills
For a passing grade the student must

• based on given prerequisites and for municipal wastewater be able to: design activated sludge processes and biofilm processes
• based on given prerequisites and for municipal wastewater be able to: design tertiary treatment processes
• based on given prerequisites and for municipal wastewater be able to: design sludge handling systems
• based on given prerequisites and for municipal wastewater be able to: to provide principle designs for removal and degradation of micropollutants
• based on given prerequisites and for municipal wastewater be able to: orally and in writing present an advanced system for wastewater treatment to other students.
• based on given prerequisites and for municipal wastewater be able to: critically examine scientific papers within certain fields of wastewater treatment.

Judgement and approach
For a passing grade the student must

• be able to assess advantages and disadvantages connected to various (selected) treatment processes based on consequences on effluent water quality, foot-print, energy efficiency and handling of bio solids.
