  1. 1. Coupling of Material Flow Analysis and Life Cycle Assessment to Analyze the Urban Metabolism of a Swedish City

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Maria Lívia Real de Almeida; [2022]
    Nyckelord :Urban Metabolism; Material and Energy Flow Analysis; Life Cycle Assessment; Environmental impact; Sustainable cities;

    Sammanfattning : Cities are responsible for an increasingly large share of environmental impacts linked to their resource consumption and production of waste. Understanding how the flows of materials and energy in urban systems contribute to environmental impacts is fundamental for urban sustainability. LÄS MER

  3. 2. Environmental Impacts of a Wastewater Treatment Plant – With Sidestream Deammonification

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Malin Ekman; [2020]
    Nyckelord :Deammonification; LCA; Life cycle assessment; WWTP; Wastewater treatment; Avloppsrening; Avloppsreningsverk; Deammonifikation; LCA; Livscykelanalys;

    Sammanfattning : Människan ger upphov till avloppsvatten varje dag. Kommunalt avloppsvatten är rikt på kol, kväve och fosfor, vilka har en stor miljöpåverkan. Vattenrening är i och med detta en nödvändighet för att minimera den antropogena inverkan på naturen och den biologiska mångfalden. LÄS MER

  4. 3. Sustainability assessment of potential wastewater treatment techniques in Tupiza, Bolivia

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Johanna Burström; [2020]

  5. 4. Partial denitrification as nitrite provider for mainstream anammox

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Felix Wallin Holmin; [2020]
    Nyckelord :Water engineering; Environmental engineering; Mainstream anammox; Partial denitrification; PDA; MBBR; Nitrogen removal; Vattenförsörjningsteknik; Avloppsteknik; Technology and Engineering;

    Sammanfattning : In traditional wastewater treatment, nitrogen is removed through the biological process combination of nitrification and denitrification. Although it is a well-established method, the need for aeration and possible addition of an external carbon source results in it being an energy-negative and costly process, thus making alternative methods for nitrogen removal compelling to examine.

  7. 5. Limiting microplastic pollution from municipal wastewater treatment : A circular economic approach

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jordy van Osch; [2020]
    Nyckelord :Microplastics; circular economy; wastewater treatment plant; resource recovery; Multi-criteria analysis;

    Sammanfattning : The increasing amount of microplastics found in the environment have underscored the urgency to identify, develop and deploy scenarios in which municipal wastewater treatment plants (MWWTPs) limit the release of urban microplastics into the environment. Simultaneously, the global trend towards a circular economy has defined the conditions for these scenarios in relation to the water-energy- nutrient nexus. LÄS MER
