  1. 21. Utredning av avloppsprocessers påverkan på recipientens mikrobiologiska status

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

    Författare :Diana Arvidsson; [2019]
    Nyckelord :Microorganisms; wastewater; sand filter; disc filter; bathing water quality; Mikroorganismer; avloppsvatten; sandfilter; skivfilter; badvattenkvalité;

    Sammanfattning : Ett avloppsvatten innehåller olika föroreningar som påverkar recipientens vattenkvalitet. En förorening somreningsverken inte är optimerade för att reducera är mikroorganismer, som i recipienten påverkar bland annatbadvattenkvalitén. LÄS MER

  3. 22. Reuse of Treated Wastewater in Industrial Symbiosis

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Greta Bürger; [2019]
    Nyckelord :Wastewater; Reuse; Symbiosis; water engineering; environmental engineering; vattenförsörjningsteknik; avloppsteknik; Chemistry;

    Sammanfattning : Many regions around the world suffer from occasional or permanent droughts. Recent years have shown that although Sweden is not a water scarce country, it is vulnerable to dry peri- ods. LÄS MER

  4. 23. Numerical simulations of mixing for gas exhaust treatment

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Viktor Lahti; [2019]
    Nyckelord :;

    Sammanfattning : According to the World Health Organisation, nine out of ten people live in places with sub par air quality. Therefore, the study of the treatment of polluted air is from a global point of view of great importance, and a matter of life quality for both humans and as well as animals. LÄS MER

  5. 24. 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.

  7. 25. Ozonation of pharmaceutical residues in a wastewater treatment plant : Modeling the ozone demand based on a multivariate analysis of influential parameters

    Master-uppsats, Linköpings universitet/Teknisk biologi

    Författare :Erica Engberg; Emilia Johansson; [2018]
    Nyckelord :;

    Sammanfattning : Most pharmaceutical residues in wastewater treatment plants (WWTPs) end up in the hydrosphere where they cause negative effects on the aquatic life and might disrupt ecosystems. By implementing an ozonation step (treatment with ozone) in the wastewater treatment process, these pharmaceutical residues can be reduced. LÄS MER
