1. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. LÄS MER
2. Pilot scale partial denitratation coupled anammox: an evaluation
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. LÄS MER
3. Nitrogen removal in MBBR : Investigating the effect of temperature
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The project undertaken in this thesis was performed at MittSverige Vatten och Avfall (MSVA) in cooperation with the Swedish Environmental Research Institute (IVL). The effect of temperature on nitrogen removal using moving bed biofilm reactor (MBBR) was controlled using two separate lines by investigating the influence of temperature on nitrification, pre-denitrification, and post- denitrification in a pilot plant scale.

4. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. LÄS MER
5. Volatile fatty acid production and application as external carbon source for denitrification
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.
