    Sammanfattning : Per- and polyfluorinated substances (PFASs) have become an urgent topic in the water treatment industry in recent years as a consequence of new scientific discoveries of the correlation between the ingestion of some PFASs and their toxicity in humans and other organisms. PFASs are synthetic compounds present in a variety of products. LÄS MER

  3. 2. 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

  4. 3. Treatment of per- and polyfluoroalkylsubstance (PFAS)-contaminated waterusing aeration foam collection

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Ylva Kjellgren; [2020]
    Nyckelord :PFAS; aeration foam collection; landfill leachate treatment; WWTP;

    Sammanfattning : Landfills are potential sources for PFASs and treatment techniques for landfill leachate are urgently needed. Foam fractionation is an aeration technique which utilizes the tendency of PFASs to escape the liquid phase and build foam. The foam is harvested and with it the contamination. LÄS MER
