  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).

    Abstract : Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. READ MORE

  5. 5. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE
