  1. 1. Electrochemical oxidation of PFAS in soil conditions : Using Boron-doped diamond electrodes and iron electrodes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Alexander Öhberg; [2022]
    Nyckelord :PFAS ELECTROCHEMICAL OXIDATION IN-SITU DESTRUCTION MINERALISATION REMOVAL;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a rising topic in the field of contaminated sites around the world, with destruction of these being an area in dire need of innovation. Previous experiments of destructive character have been proven efficient using boron doped diamond electrodes (BDD) in small scale electrochemical cells. LÄS MER

  3. 2. Potential policy projects for decreasing fluoride concentrations in the groundwater of Aguascalientes, Mexico : a cost-benefit analysis

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Elice Fällström; [2022]
    Nyckelord :aguascalientes; cost-benefit analysis; fluoride removal; centre pivot irrigation; sustainable development; environmental policy;

    Sammanfattning : Reductions in groundwater quality due to aquifer depletion is a growing issue globally and will become more prominent with continued climate change and population growth. Dry regions are particularly vulnerable to this issue due to their reliance on groundwater for water supply. LÄS MER

  4. 3. Fluoride removal by low-cost adsorbents

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Fredrik Bernheim; [2022]
    Nyckelord :Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Sammanfattning : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. LÄS MER

  5. 4. Removal of Arsenic in Ground Water from Northern Burkina Faso through Adsorption with Granular Ferric Hydroxide : A SIDA Minor Field Study at the Department of Chemistry, University of Ouagadougou

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Hannes Öckerman; Emma Lundin; [2013]
    Nyckelord :Burkina Faso; arsenic; Granular Ferric Hydroxide; adsorption; column test; drinking water; ground water; self-regeneration;

    Sammanfattning : The need of making arsenic contaminated ground water potable is urgent in parts of Burkina Faso. An implementation of a treatment design using Granular Ferric Hydroxide (GFH) is under development. Water from a tube-well in Lilgomdé, Yatenga province, Burkina Faso, has been treated with the adsorbent GFH through column experiments. LÄS MER

  7. 5. Enhancing the capacity of seeds as turbidity removal agents in water treatment. : A Minor Field Study.

    Master-uppsats, KTH/Miljögeokemi och ekoteknik

    Författare :Annika Blix; [2011]
    Nyckelord :drinking water treatment; natural coagulants; Parkinosnia aculeata; Vigna unguiculata;

    Sammanfattning : The aim of this master’s thesis was to investigate if defattening of Parkinsonia aculeata (in swahili “mkeketa”) and Vigna unguiculata (in swahili “choroko”) would enhance the capacity of the seed’s properties in removing suspended particles from surface water. The seeds are used in local traditional treatment of drinking water in Tanzania. LÄS MER
