    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sofia Mile; [2023]
    Nyckelord :Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Sammanfattning : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. LÄS MER

  3. 2. Study of mixing and exchange in a drinking water reservoir using CFD modeling

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

    Författare :Nadja Rabizadeh; [2023]
    Nyckelord :CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Sammanfattning : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. LÄS MER

  4. 3. Insamling av dagvatten för toalettspolning i Sverige : Undersökning av befintliga system i Celsiushuset och Sergelhusen med avseende på effektivitet, drift och användarupplevelse

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Simon Larsson; Martin Lindkvist; [2023]
    Nyckelord :Dagvatten; dagvatteninsamling; vattenrening; nederbörd; toalettspolning; återanvändning av regnvatten;

    Sammanfattning : Collecting rainwater for use in toilets is currently uncommon in Sweden. Technology for treatingrainwater and using it for toilet flushing is only found in three buildings in Sweden today. Twoof these buildings are Celsiushuset in Uppsala and Sergelhusen in Stockholm. LÄS MER

  5. 4. Potential for Enhanced Biological Phosphorus Removal in an activated sludge system for greywater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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.

  7. 5. Spatial patterns of Dissolved Organic Matter in Swedish Surface Waters

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Anna Lackner; [2022]
    Nyckelord :Dissolved Organic Matter; Brownification; Digital Mapping; Soil Moisture; Stream Length;

    Sammanfattning : Dissolved organic matter (DOM) in surface water has been widely studied, in part due to its significance for aquatic ecology and drinking water quality. Across Sweden, increases in the total organic carbon (TOC) concentrations and color of surface waters, known as brownification, were noted in the decades before and after year 2000, though recent analysis has found widespread DOM increase to have ceased after 2010.
