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: 1) provide in-depth knowledge of principles and methods for mechanical, biological and chemical wastewater treatment 2) provide tools to apply in selection and design of advanced wastewater treatment systems.
Knowledge and Understanding
For a passing grade the doctoral student must be able to suggest suitable treatment technologies for a wastewater stream with given prerequisites in terms of hydraulic loading, pollutant loading and effluent requirements.
Competences and Skills
For a passing grade the doctoral student must based on given prerequisites and for municipal wastewater be able to design activated sludge processes and biofilm processes, design tertiary treatment processes, design sludge handling systems, provide principle designs for removal and degradation of micropollutants, orally and in writing present an advanced system for wastewater treatment to other students, and critically examine scientific papers within certain fields of wastewater treatment.
Judgement and Approach
For a passing grade the doctoral 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.
The design process - data evaluation and process selection The activated sludge process - principles and design Biofilm processes - principles and design Tertiary treatment - principles and design Membrane bioreactors and direct membrane filtration of raw wastewater Alternative nitrogen removal Sludge handling and anaerobic digestion - principles and design Removal of micropollutants Source sorting Urban infrastructure and stormwater treatment
