1. 1. Thermal degradation of PFAS in solid matter

   University essay from KTH/Kemi

   Author : Tuqa Al-Badri; [2024]
   Keywords : PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

   Abstract : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. READ MORE

3. 2. 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

4. 3. 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).

5. 4. Investigating the Adsorption of Per- and Polyfluoroalkyl Substances on Amine-functionalized Mesoporous Carbons

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : MOJISOLA SALISU; [2023]
   Keywords : Mesoporous carbon; PFOA; PFOS; PFAS; Rose Bengal; Adsorption;

   Abstract : Water pollution is a profound ecological concern, exerting detrimental effects on human well-being, ecological systems, and animal life. Among the emerging contaminants that critically influence water quality and have garnered substantial scientific interest in recent times are per- and polyfluoroalkyl substances (PFAS). READ MORE

6. 5. Investigation of unknown groundwater flows to two leachate ponds at Hovgården

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Katja Nordström; [2023]
   Keywords : landfill; leachate; principle component analysis; PCA; polishing pond;

   Abstract : The leaching of groundwater into two polishing ponds, the last step in the wastewater treatment process on Hovgarden waste facility, was examined. The focus of this study was to analyse the PFAS composition profile (fingerprint) to trace the leaching groundwater. READ MORE
