Exjobbsförslag våren 2021: Jämförelse mellan metoder för karakterisering av organiskt material i avloppsvatten
Master’s thesis proposal spring 2021
Comparison of methods for fractionation of organic matter in municipal wastewater
Knowledge about the characteristics of the organic matter in raw municipal wastewater improves design, operation and mathematical modelling of physical-chemical and biological wastewater treatment methods. However, an evaluation and comparison of different methods for fractionation of soluble, colloidal and suspended organic matter and characterisation of their biodegradability in wastewater are lacking for Swedish conditions.
NSVA, a municipal association operating the water and wastewater works in seven municipalities in northwestern Scania, and RISE Research Institutes of Sweden have just started a research project to develop a real-time model based decision support tool for the Öresund Wastewater Treatment Plant (WWTP). One milestone in the project is to build a calibrated and validated a process model of the WWTP.
The main aim of this project is to evaluate and compare different methods for fractionation of soluble, colloidal and suspended organic matter and characterisation of their biodegradability in municipal wastewater.
The fractionation of organic matter is performed by coagulation-flocculation and/or filtration. The biodegradability is analysed by chemical analyses and/or respirometry. The laboratory work is performed at the Öresund WWTP in Helsingborg.
Previous experience of laboratory work is a prerequisite for the project.
