  1. 16. The possibilities of recycling wash water at Vidinge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Julia Mauritzson; [2020]
    Nyckelord :reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Sammanfattning : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. LÄS MER

  3. 17. Screening of per- and polyfluoroalkyl substances (PFASs) in drinking water in Sweden

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

    Författare :Erik Gunnars; [2020]
    Nyckelord :PFASs; drinking water; per- and polyfluoroalkyl substances; persistent organic pollutants; PFOA; PFOS;

    Sammanfattning : Worldwide use of per- and polyfluoroalkyl substances (PFASs), both legacy and past, are problematic due to their persistent nature. To date, PFASs are of high concern since they have been found not only in the environment but also in animals, plants and humans. LÄS MER

  4. 18. Per- and Polyfluoroalkyl Substances (PFASs) Removal from Landfill Leachate : Efficiency Evaluation in Column Experiments

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

    Författare :Emelie Johnson; [2019]
    Nyckelord :;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are known for their wide spread in the environment, their persistent properties and their ability of biomagnification through the food chain. With properties such as oil and water repellence, temperature resistance and a long lifespan they have been frequently used in various areas, e.g. LÄS MER

  5. 19. Hur hanteras algblomning i dricksvattentäkt – en undersökning av algblomning i Bondsjön, Härnösands kommun, och förslag till åtgärder

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Johanna Sjölund; [2019]
    Nyckelord :algblomning; cyanobakterier; cyanotoxin; vattenrening; aktivt kolfilter; membranfilter;

    Sammanfattning : Algal blooms are a common phenomenon in lakes and seas in and around Sweden and poses a problem when found in a drinking water source. Some cyanobacteria can produce toxins which can be with a health problem. To get a safe drinking water it is necessary to be able to remove the toxins from the incoming water. LÄS MER

  7. 20. Possibilities for removal of micropollutants in small-scale wastewater treatment - methods and multi-criteria analysis

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

    Författare :Anqi Li; [2018]
    Nyckelord :pharmaceuticals; column experiment; removal efficiency; absorbents;

    Sammanfattning : The quality of worlds’ water resources is facing new challenges, for instance detectable concentration of various trace contaminants under the term micropollutants is discharging into water bodies from both municipal wastewater treatment plants and from on-site wastewater facilities. A project called RedMic aim at identifying and quantifying emissions of micropollutants from on-site wastewater treatments as a basis for providing innovative treatment technologies to reduce potential risks for groundwater and surface water contamination.
