  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).

  2. 2. 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

    Author : Hiwa Oveisy; [2023]
    Keywords : drinking water; in-line coagulation; inline coagulation; jar test; membrane filtration; NOM removal; treatment; ultrafiltration; behandling; dricksvatten; inlinekoagulering; krusprov; membranfiltrering; NOM-borttagning; onlinekoagulering; ultrafiltrering;

    Abstract : Abstract The removal of Natural Organic Matter (NOM) from water supplies is crucial for the provision of clean, safe drinking water. Lab-scale experiments have been extensively utilized in water treatment facilities to optimize this process. The most used lab-scale method is known as jar test. READ MORE

  3. 3. Evaluation of two-stage GAC filtration for PFAS reduction in drinking water

    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. 4. Implementation of an automatic tangential flow filtration system for latex immunoassay production

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

    Author : Filippa Stolpe; Sofia Kullander; [2023]
    Keywords : biotechnology; bioprocess; diagnostics; production; TFF; tangential flow filtration; blood clots; automation; antibodies; latex immunoassay; LIA;

    Abstract : To diagnose patients suffering from blood clotting disorders latex immununoassays (LIA) can be used. A time consuming manual tangential flow filtration (TFF) process suggests the implementation of an automatic TFF system to improve the efficiency, profitability, and expandability of the production facility of LIA at Nordic Biomarker.

  5. 5. Towards low carbon buildings: A case study in Sweden

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Keywords : Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.
