  1. 1. Is two stage GAC better than one stage GAC for removing PFAS at a DWTP? : Investigation of PFAS removal from drinking water using two stage granular activated carbon (GAC) filter

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Oliver Ekesiöö; [2023]
    Keywords : GAC; PFAS; drinking water treatment; two stage GAC;

    Abstract : The removal of 34 per- and polyfluoroalkyl substances (PFAS) were compared in a 1 stagegranular activated carbon (GAC) filtration to a 2 stage GAC filtration in a pilot study at adrinking water treatment plant (DWTP). The PFASs that were present in the water wereperfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluoropentanoic acid(PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), perfluorobutanesulfonic acid (PFBS), perfluoropentane sulfonic acid (PFPeS) and perfluorohexane sulfonic acid(PFHxS).

  3. 2. Yearly distribution and composition of per- and polyfluoroalkyl substances (PFAS) in Luleå wastewater treatment plant

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Moa Sjöberg; [2023]
    Keywords : PFAS; WWTP; Wastewater treatment; Consumer products; Precursors;

    Abstract : PFAS (per- and polyfluoroalkyl substances) are a large group of substances that are used in a large variety of products because of their unique water and dirt repellent properties. The substances are extremely persistent and can spread over large distances in groundwater, surface water, and in the air, which makes them an environmental and a health concern. READ MORE

  4. 3. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    University essay from KTH/Industriell bioteknologi

    Author : Emma Eriksson; [2023]
    Keywords : Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Abstract : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.
