  1. 6. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  3. 7. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Mehrzad Ghassemi; [2022]
    Keywords : Greywater; EBPR; Phosphorus; Biological treatment; Water and environmental engineering; Technology and Engineering;

    Abstract : As the world's population grows, concerns about water scarcity and rising pollution such as phosphorus and nitrogen have increased significantly. Greywater has been considered by researchers as an ideal alternative to fresh water for decades, and several projects have been implemented to treat and recycle it for various reuse purposes.

  4. 8. Thermochemistry modelling applied to activated sludge process: Feasibility assessment

    University essay from KTH/Proteinvetenskap

    Author : Maylis Fournier; [2022]
    Keywords : activated sludge; modelling; thermodynamics; microbial growth; aktivt slam; modellering; termodynamik; mikrobiell tillväxt;

    Abstract : Aktivt slam är en biologisk process som används i stor utsträckning för rening av avloppsvatten, där bakterier som odlas under luftiga förhållanden avlägsnar organiska ämnen och näringsämnen från förorenat vatten. För industriell verksamhet modelleras denna process för att representera och förutsäga biologiska fenomen. READ MORE

  5. 9. Post-Denitrification on Sand Filter at Bromma Wastewater Treatment Plant

    University essay from KTH/Kemi

    Author : Emil Blocksjö; [2022]
    Keywords : Sand filter; Post-Denitrification; Nitrate; Nitrification; Wastewater; Sandfilter; Efterdenitrifikation; Nitrat; Nitrifikation; Avloppsvatten;

    Abstract : Examensarbetets syfte var att undersöka möjligheter till denitrifikation på sandfilter (SF) i industriell skala och hur det jämför sig med konventionella metoder för att uppnå denitrifikation och effekten av förändringen på processen vid Bromma reningsverk. Parametrar som undersöktes var rening av ammonium och nitrat, luftning, temperatur, pH, rening av fosfor, rening av organiskt material, rening av suspenderat material, förbigång av vatten vid SF och aktivslamanläggning (ASA), drifttider för SF:arna och total vattenbelastning på ASA och SF.

  6. 10. Investigation into the Removal of the By-product NDMA (N-Nitrosodimethylamine) from Ozonation Process in Wastewater Treatment

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Zehao Li; [2021]
    Keywords : Water resources engineering; Ozonation; NDMA; Wastewater; pharmaceutical; Diclofenac; Ibuprofen; Naproxen; Technology and Engineering;

    Abstract : In people’s modern life, daily usage of artificial compounds such as active pharmaceuticals ingredients (API) is usual. These compounds are likely to end up as micropollutants in the municipal wastewater. Municipal wastewater is the major source of pharmaceuticals in the aquatic environment. READ MORE
