  1. 21. Modelling control strategies for chemical phosphorus removal at Tivoli wastewater treatment plant

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Sara Rosendahl; [2021]
    Nyckelord :Wastewater treatment plant; phosphorus precipitation; control strategy; feedforward; feedback; ASM2d and primary clarifier model.;

    Sammanfattning : Wastewater compose an environmental risk as it contains high levels of nutrients, including phosphorus. Wastewater treatment plants (WWTPs) reduce phosphorus by using coagulants that precipitate soluble phosphate into metal phosphate, which is separated by settling. LÄS MER

  2. 22. Separation of microfibers from laundry waste water by hydrocyclone : In cooperation with Electrolux Professional

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Anna Cecilia Carolina Lorentzon; [2021]
    Nyckelord :microfiber separation; microfibre separation; hydrocyclone; hydrocyclonic separation; microfibers; microfibres; laundry effluent; laundry waste water; laundry wastewater;

    Sammanfattning : Microfibers, textile fibres shorter than 5 mm, and are shed from fabrics during wear and released into the laundry effluent during washing. When passed through the wastewater treatment plant (WWTP), they adsorb toxins, heavy metals and pathogens before being released into the environment. LÄS MER

  3. 23. Bromatreducering i den biologiska denitrifikationsprocessen – påverkan av bromat och nitrat

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Sandra Fransson; [2021]
    Nyckelord :Vattenrening; Bromat; Denitrifikation; Vattenförsörjnings- och avloppsteknik; Technology and Engineering;

    Sammanfattning : Behovet av att rena avloppsvatten från mikroföroreningar, såsom läkemedelsrester, har uppmärksammats de senaste åren då analysmetoderna har förbättrats och kunskapen om riskerna kring utsläppen har ökat. Detta har ökat intresset för att implementera ozonering som ett avancerat reningssteg på avloppsreningsverk i Sverige och i andra länder. LÄS MER

  4. 24. Removal of per- and polyfluoroalkyl substances(PFAS) from contaminated leachate usingaeration foam fractionation

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Axel Krögerström; [2021]
    Nyckelord :PFAS; Foam Fractionation; Leachate; Removal Efficiency; Wastewater Treatment;

    Sammanfattning : Leachate from landfills is contaminated in many ways and per- and polyfluoroalkyl substances (PFAS)-contamination is one of them. Recent studies have demonstrated the environmental and human concerns of PFAS. Therefore, the treatment of leachate is important. LÄS MER

  5. 25. Influence of Climate Change on Building Effluent Wastewater Temperature in Stockholm by 2040

    Master-uppsats, KTH/Energiteknik; KTH/Farkostteknik och Solidmekanik

    Författare :Sorhenn Gourhand Martin; [2021]
    Nyckelord :;

    Sammanfattning : This report aims to give predictions of Stockholm’s region climate (especially temperature and precipitations) by 2040 and describe the consequences of possible climate changes on the building effluent water temperature and flowrate. First, I did an extensive review of the literature about climate change and climate prediction in Stockholm’s area in order to suggest probable climate scenarios for 2040, using climatic data from the reference period 1960-1990.
