  1. 21. Bluegreengrey (BGG) solution for future climate and flood-resilient urban drainage network by enhancing the natural hydrological cycle

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Adnan Asif Rifat; [2023]
    Nyckelord :Bluegreengrey; Sustainable stormwater; Basement flooding; Urban flooding; Pipe Network; BGG; Climate change; Hydrology; Mike .; Technology and Engineering;

    Sammanfattning : A loop of urbanization, increasing impervious surface in urban areas, increasing temperature, rainfall, surface runoff and flooding, and lack of new spaces have been adding challenges to urban drainage systems for decades. The climate change impacts are exposing the existing vulnerable conventional urban drainage systems to more challenges in the future. LÄS MER

  3. 22. Upptagshastigheter av metaller med salix

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Anton Lilja; [2023]
    Nyckelord :phytoremediation; phytoextraction; salix; metals; landfill leachate; leachate management; fytosanering; fytoextraktion; salix; metaller; deponilakvatten; lakvattenhantering;

    Sammanfattning : Phytoremediation is a technology that can be used in several ways to remediate polluted soils and water. Today, phytoremediation is viewed by many as a technology in the development phase and therefore it is important to evaluate existing facilities to create more support for future establishment.

  4. 23. 3D CFD Simulations of Hydrogen Engine Combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Hao Liu; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the trend of decarbonization, the transport sector is exploring possibilities of fossil fuel free solutions. Hydrogen can be a potential fuel for future engine applications. In this work, the concept of H2 HPDI is investigated, where a pilot diesel injection ignites the hydrogen jet. LÄS MER

  5. 24. Distributionssystem för lågtempereradfjärrvärme i framtida bostadsområden : Fallstudie för stadsomvandlingsprojektet Näringen iGävle

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

    Författare :Oskar Olsson; [2023]
    Nyckelord :4th generation district heating; distribution systems; simulation; energy efficiency; cascading;

    Sammanfattning : In Europe, the prices of natural gas and electricity reached an all-time high during 2022. An approach tomitigate these high prices is to expand the district heating systems in urban areas, this will reduceelectric load as well as to increase the power production in combined heat and power plants.

  7. 25. A Toxic Legacy? : A Study of PFAS Leakage from Landfills in the Eastern Part of Mälaren

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

    Författare :Elsa Hård af Segerstad; [2023]
    Nyckelord :Landfills; PFAS; Leachate; Mälaren-Görväln; Östra Mälaren Water Protection Area; Norrvatten; Drinking Water; Characterisation; Risk Assessment; Deponier; PFAS; Lakvatten; Mälaren-Görväln; Östra Mälarens vattenskyddsområde; Norrvatten; Dricksvatten; Karakterisering; Riskbedömning;

    Sammanfattning : The growing concern around per- and polyfluoroalkyl substances (PFAS) and their negative health and environmental effects have lately become more apparent which also is reflected in the new, more strict regulations of permitted levels of PFAS in drinking water extracted from water resources. However, many point sources of PFAS pollution to the environment and to water resources are still not identified and assessed for risk. LÄS MER
