  1. 1. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Amanda Carlund; [2023]
    Keywords : ;

    Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

  3. 2. 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).

  4. 3. PFAS in a Swedish wastewater treatment plant : An analysis of the effectiveness of major treatment steps on 33 PFAS

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

    Author : Jonatan Forsberg; [2022]
    Keywords : Northern Sweden; PFAS; municipal WWTP; MBBR; GAC;

    Abstract : Wastewater treatment plants (WWTP) are known spreaders of per- and polyfluoroalkyl substances (PFAS) into the environment. Luleå University of Technology is conducting a yearlong study in which PFAS concentrations in the different treatment steps are measured at Uddebo treatment plant. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emelie Johnson; [2019]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Sorption of perfluorinated and polyfluorinated alkylated substances (PFASs) in the subsurface of an industrial site in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Carl Sköld; [2019]
    Keywords : Sorption; soil-water partitioning; Kd; PFOS; PFOA; PFHxS; Sorption; fördelningskoefficient; Kd; PFOS; PFOA; PFHxS;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of emerging chemicals which havereceived increasing attention due to their toxicity, persistent properties, and global distribution.In this study, sorption coefficients (Kd and KOC) of PFASs in an industrial site in Sweden wereevaluated.
