  1. 11. Hälsorisker och kostnader i samband med avsaltat dricksvatten

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

    Författare :Virginia Rahmani; [2022]
    Nyckelord :desalinated drinking water; desalination plant; healthrisks; desalination process; cost; Avsaltat dricskvatten; avsaltningsanläggningar; hälsorisker; avsaltninsprocesser; kostnader;

    Sammanfattning : I takt med att vattenbristen ökar har flera länder börjat använda avsaltning, en innovation som framställer rent men mineralfattigt vatten, för att möta vattenbehoven. Detta kandidatarbete ämnar att bidra med vidare kunskap kring avsaltat dricksvatten med bakgrund till tidigare forksning. LÄS MER

  3. 12. Challenges and opportunities with shared data for Water Treatment Plants

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Johanna Bredhe; Abdulahi Ismail Hashi; [2022]
    Nyckelord :water treatment plants; shared data; water treatment processes; oxidation; chemical treatment; filtration; disinfection; open data; vattenverk; delade data; vattenreningsprocesser; oxidation; kemisk fällning; filtration; desinfektion; öppna data;

    Sammanfattning : The Swedish water sector faces many challenges in terms of climate change, worn out facilities and distribution systems as many of them were built in the 50-, 60- and 70s, but also increased cyber security concerns. Collaborations between different actors are therefore required to address these challenges. LÄS MER

  4. 13. Life Cycle Assessment of a small scale, solar driven HVR water purification system

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Sharang Kolathur; [2022]
    Nyckelord :life cycle assessment; air gap membrane distillation; solar energy; levelized cost; grid operated system; livscykelanalys; luftgapmembrandestillation; solenergi; utjämnade kostnader; nätdrivet system;

    Sammanfattning : Water purification systems have made access to drinking water easier by treating water sources which previously could not be used for drinking. Such systems however require energy and materials to build and operate which means they have environmental impacts. LÄS MER

  5. 14. Dynamics of Hydro-power Development in Nepal: Water-Energy-Food Security Prospect

    Master-uppsats,

    Författare :Jaya Lal Neupane; [2022]
    Nyckelord :Sustainable Development; Sustainable Hydropower; WEF Security; Benefit-sharing; Trade-offs; Benefits;

    Sammanfattning : This thesis concerns with water, energy, and food (WEF) security in Nepal in relation to hydropower development. Hydropower is challenging to WEF security in three ways: First, the focus is only on energy generation which overlooks the impacts on land, forest, water and biodiversity. LÄS MER

  7. 15. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Klara Lindqvist; [2022]
    Nyckelord :Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Sammanfattning : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. LÄS MER
