  1. 1. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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.
