  1. 1. Pyrolysis of Municipal Sewage Sludge to get a phosphorus rich char residue for soil improvement

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahin Shamim; [2023]
    Nyckelord :Sewage Sludge-Phosphorus-Pyrolysis- Heavy metals; Cadmium; Lead; Nickle; Copper; Chromium; Zinc; Biochar; Heating value; Fertilizer- Thermal conversion;

    Sammanfattning : Sewage sludge is a byproduct of wastewater treatment plants. It is a kind of waste. however, it contains several valuable nutrients like phosphorous and nitrogen that are used to rich the soil as a fertilizer compound. LÄS MER

  3. 2. Identification of Vanadium-Binding Ligands in White Wine

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

    Författare :Freja T Trybom; [2023]
    Nyckelord :Vanadium; LD converter slag; wine; food waste; recycling.;

    Sammanfattning : Vanadin är en värdefull metall och kan lakas ur LD (Linz-Donawitz)-slagg med hjälp av vin. Ligander i vinet som lakar vanadin från LD-slagg studerades i denna rapport med mål att identifiera några av deras egenskaper såsom apparent molekylmassa och spektral information. 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. Analyzing components of barrier coatings in different fractions during a repulping process.

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

    Författare :Evelina Särnholm; [2021]
    Nyckelord :ICP-MS; MP-AES; GC-MS; repulping process; paper; poly ethylene-co-acrylic acid ;

    Sammanfattning : During paper manufacturing, coating and adhesives are added to paper and cardboard to improve quality and durability. When the paper is later recycled or becoming new paper, the coatings may pollute the water used in the recycling process. Thus, it is important to know in which fraction these coatings finish during the process. LÄS MER

  7. 5. Investigation of the Metal Content in Cress Seedlings fed with increased Concentration of Lead & Iron Solutions

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

    Författare :Nikita Burton; [2020]
    Nyckelord :Cress; iron; lead; metals; acidified digestion; MP-AES; ICP-MS;

    Sammanfattning : Metals are essential nutrients for plant health, but not all metals are necessary and can sometimes be harmful towards plants depending on factors such as species, elemental composition in the soil and concentration of a metal. Iron (Fe), which is one of the most abundant metals in the earth’s crust is also one the most important nutrients for plant growth, as it is responsible for metabolism. LÄS MER
