  1. 6. PFAS in a Swedish wastewater treatment plant : An analysis of the effectiveness of major treatment steps on 33 PFAS

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonatan Forsberg; [2022]
    Keywords : Northern Sweden; PFAS; municipal WWTP; MBBR; GAC;

    Abstract : Wastewater treatment plants (WWTP) are known spreaders of per- and polyfluoroalkyl substances (PFAS) into the environment. Luleå University of Technology is conducting a yearlong study in which PFAS concentrations in the different treatment steps are measured at Uddebo treatment plant. READ MORE

  3. 7. Nitrogen removal in MBBR : Investigating the effect of temperature

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rediet Tezera Tafese; [2022]
    Keywords : Wastewater; Nitrogen removal; Nitrification; Denitrification; MBBR; Cold temperature; Avloppsvatten; Kväverening; Nitrifikation; Denitrifikation; MBBR; låg temperatur;

    Abstract : 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. 8. Effect of biofilm thickness and carrier type on the performance of anaerobic moving bed biofilm reactors (AnMBBRs)

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Astrid Hermansson; [2020]
    Keywords : Anaerobic; wastewater treatment; AnMBBR; MBBR; biofilm thickness; carrier; organic removal; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Abstract : 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. READ MORE

  5. 9. Volatile fatty acid production and application as external carbon source for denitrification

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Cora Michelle Döhler; [2020]
    Keywords : VFAs; co-fermentation; primary sludge; food waste; denitrification; external carbon source; MBBR;

    Abstract : 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.

  6. 10. Considerations for the Establishment of an Anaerobic Biofilm in an AnMBBR

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Emma Månsson; [2020]
    Keywords : Anaerobic; MBBR; biofilm; carrier; methane; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Behandling av avloppsvatten för att avlägsna ämnen som kan ha en negativ påverkan på den mänskliga hälsan och naturen är mycket viktigt innan vattnet återanvänds eller släpps ut i naturen. Intresset för anaerob vattenrening har ökat eftersom det är ett bra komplement till aeroba processer, samt för att det producerar energi i form av metangas. READ MORE
