  1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  3. 2. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Linnea Sjökvist; [2023]
    Nyckelord :Membrane filtration; ultrafiltration; PHA; polyhydroxyalkanoates; chemical engineering; Technology and Engineering;

    Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER

  4. 3. 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

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Dagvatten blir badvatten : ett gestaltningsförslag på en baddamm i Gränbyparken med naturlig rening

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Urban and Rural Development

    Författare :Ludvig Pärlefors Prado; [2023]
    Nyckelord :Baddamm; dagvattenrening; naturlig pool; hållbar dagvattenhantering;

    Sammanfattning : Att rena och fördröja dagvatten sker i allt högre grad lokalt. Då dagvattenanläggningarna kommer närmare inpå den bebyggda miljön och i kontakt med stadens invånare, får landskapsarkitekten en viktig roll, genom att utforma öppna dagvattenlösningar. LÄS MER

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

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Söderberg; [2023]
    Nyckelord :Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

    Sammanfattning : 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. LÄS MER
