  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  3. 2. 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

  4. 3. Intensification of lignocellulosic bioethanol production process using multi-staged membrane bioreactors

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

    Författare :Clarisse Uwinez; [2019]
    Nyckelord :Interconnected continuous hydrolysis and fermentation; lignocellulosic bioethanol; Membrane bioreactors; process intensification; lignin recovery; membrane fouling.;

    Sammanfattning : The exploitation of lignocellulosic materials with the aim of producing high value-added products will potentially counteract concerns related to the depletion of fossil resources or exponential population growth. Bioethanol produced from lignocellulosic agriculture residue exhibits promising alternative to the petroleum-based fossil fuel which reduces net emission of greenhouse gases (GHG). LÄS MER

  5. 4. Environmental Impact of Wastewater Treatment - A Study of Membrane Bioreactor and Iso-Disc Technologies from a Life Cycle Perspective

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Isabelle Zilling; Krister Lestander; [2019]
    Nyckelord :MBR technology; Iso-Disc technology; Life cycle assessment; Wastewater treatment; Conventional activated sludge process; Activated sludge process; Electricity mix; Technology and Engineering;

    Sammanfattning : This study evaluates and compares two different wastewater treatment technologies from a life cycle perspective. The evaluating technologies are Membrane Bioreactor (MBR) technology with a microfiltration membrane and Iso-Disc technology. LÄS MER

  7. 5. Development and evaluation of a pre-analytical device for liquid biopsy

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Nicole Yacoub; [2018]
    Nyckelord :;

    Sammanfattning : In this project, a novel method to discover and monitor cancer was studied. Tumoureducated platelets (TEPs) have shown the ability to take up tumour-derived secretedmembrane vesicles, which contain tumour RNA. Therefore they are of great interestfor detecting cancer and could potentially work as biomarkers. LÄS MER
