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. Automation of a rotating bed reactor for PFAS remediation

   University essay from Umeå universitet/Institutionen för fysik

   Author : Axel Martin; [2023]
   Keywords : Programming; automation; experimentation; optimization;

   Abstract : Properties such as being water and oil repellent and being heat resistant make per- and polyflouroalkyl substances (PFAS) useful in a wide range of products. Since they do not break down in the environment, PFAS pollution makes it way back into drinking water and seafood. READ MORE

   Author : Madeleine Vikström; [2023]
   Keywords : PFAS4; drinking water production; dissolved air flotation; granular activated carbon filter; sludge management; PFAS4; dricksvattenproduktion; flotation; granulärt aktivt kolfilter; slamhantering;

   Abstract : Norrvatten är en av Sveriges största dricksvattenproducenter. Med ett ökande behov av en större produktionskapacitet och nya regleringar, planerar dem att förbättra sin reningsprocess. En aspekt som kräver omfattande undersökning är val av reningsmetod för att nå den nya gränsen från Livsmedelsverket för fyra PFAS kemikalier. READ MORE

5. 4. Optimizing Conditions of Coagulation for Removal of Natural Organic Matter (NOM) : Comparison of Removal Efficiency of NOM When Using Bench-Scale Inline Coagulation Over Ultrafiltration and Classical Jar Tests

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära
