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).

   University essay from SLU/Department of Molecular Sciences

   Author : Julia Söderberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

   Abstract : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. READ MORE

4. 3. Future sludge management from a sustainability perspective

   University essay from KTH/Proteinvetenskap

   Author : Ebba Simensen; [2023]
   Keywords : Sludge management; Waterworks sludge; Drinking water treatment; LCA; MCDA; Slamhantering; Vattenverksslam; Dirksvattenrening; LCA; MKA;

   Abstract : Syftet med projektet är att undersöka effekten av att leda över vattenverksslam från Norrvattens vattenverk, Görvälnverket, till Käppalaverkets reningsverk som ett steg i en mer hållbar slamhantering. Detta slamhanterings alternativ jämförs med en framtida lokal slamhantering vid Görvälnverket. READ MORE

5. 4. Evaluation of PFAS removal from nanofiltration membrane concentrate using foam fractionation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : William Stefansson; [2022]
   Keywords : PFAS; Aeration foam fractionation; Nanofiltration membrane; DWTP; Surfactant; PFAS; Skumfraktionering; Nanofiltration; Vattenverk; Surfaktant;

   Abstract : 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. READ MORE
