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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  3. 12. Utvärdering av teknik relaterad till rening av PFASsom installerats med stödet av statsbidraget för bättrevattenhushållning

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Homera Bayati; [2023]
    Nyckelord :PFAS; Drinking water; Government grant; Water purification; Activated carbon; PFAS; Dricksvatten; Statsstöd; Vattenrening; Aktivt kol;

    Sammanfattning : Per- och polyfluorerade alkylsubstanser (PFAS) är vidd spridd och har upptäckts i miljön i Sverige och Europa (Naturskyddsföreningen, 2023). På vissa ställen har det uppmätts höga halter i vattentäkter för dricksvatten till exempel nära brandövningsplatser. LÄS MER

  4. 13. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER

  5. 14. Characterization of Cobalt Prussian Blue Analogue in Capacitive Deionization

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Zaid Akrawi; Twana Hassan Cheragwandi; [2022]
    Nyckelord :capacitive deionization; CDI; water purification; Prussian Blue; electrochemistry;

    Sammanfattning : Clean, drinkable water is nowadays taken for granted in most developed coun-tries. However, over two billion people in the world do not have access to drink-ing water. In an attempt to combat this, capacitive deionization (CDI) hasgained increased attention in recent years. LÄS MER

  7. 15. Reducing the environmental impact of new neighbourhoods during early planning stages using life cycle analysis (LCA) : Towards effective decision support tools for settlements projects

    Master-uppsats, KTH/Byggvetenskap

    Författare :Pierrick Francois Gervasi; [2022]
    Nyckelord :district LCA; residential neighbourhood; EPD; Urban Print; urban; modelling; normalization; weighing; planet boundaries.;

    Sammanfattning : Since the first warnings on the limits of planet Earth, 50 years ago, policies havenot been sufficient and fast enough to create a more sustainable world, which is todayillustrated by climate change, an increase in resource scarcity, and tremendousbiodiversity loss. Cities have been playing an important role in those environmentalconsequences, today accounting for 60% of greenhouse gases. LÄS MER
