  1. 1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Felicia Hagberg; [2024]
    Nyckelord :PFAS; PFCA; PFSA; stormwater; guidelines; foam fractionation; activated carbon; anion exchangers; PFAS; PFCA; PFSA; dagvatten; riktvärden; åtgärder; skumfraktionering; aktivt kol; jonbytare;

    Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

  3. 2. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  4. 3. Monte Carlo evaluation of static and dynamic 6FFF treatments - Evaluation of dose distributions calculated with AAA, Acuros XB, and Collapsed Cone (RayStation and DoseCheck)

    Master-uppsats,

    Författare :Alma Blombäck; [2023-02-23]
    Nyckelord :Medical physics; Monte Carlo; 6FFF; AAA; Acuros XB; DoseCheck; RayStation; DVH evaluation; flattening filter free;

    Sammanfattning : There are several benefits to removing the standard flattening filter and using so-called flattening filter free (FFF) treatments in external radiation therapy with photons. The main advantage is the possibility of significantly shortening the treatment time, de spite this FFF is not widely used yet. LÄS MER

  5. 4. EU-taxonomins bidrag till strategiskt hållbarhetsarbete : En omvärldsanalys och fallstudie inom vatten- och avloppsledning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Moa Toll; [2023]
    Nyckelord :EU-taxonomy; Taxonomy regulation; European Commission; Framework for Strategic Sustainable Development; FSSD; BREEAM Infrastructure; Activities; Criteria; Water and wastewater; W WW; Sustainability reporting; EU-taxonomi; Taxonomiförordning; Europa Kommissionen; Aktivitet; Kriterium; Miljömässigt hållbar; VA-ledning; Vatten- och avloppsledning; Hållbarhetsrapportering;

    Sammanfattning : Mankind has worked with the climate crisis and other sustainability issues since the 1990s, but this hasn’t had any desired effect. One of the problems relates to interpretations of the term sustainability. It has caused confusion, and work towards developing shared understandings is still an ongoing process. LÄS MER

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

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

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

    Sammanfattning : 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). LÄS MER
