  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. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Wessén; [2023]
    Nyckelord :Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Sammanfattning : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  4. 3. 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

  5. 4. Method development of magnetic cell isolation and DNA extraction of small cell populations from Ficoll-separated hematopoietic cells

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Dominika Debowska; [2023]
    Nyckelord :Clonal haematopoiesis of indeterminate potential CHIP ; hematopoietic stem cell; automated cell separation; silica-membrane-based nucleic acid purification.;

    Sammanfattning : Clonal haematopoiesis of indeterminate potential, or CHIP are a family of mutations present in the general population. CHIP-mutations are prevalent in the haematopoietic stem cells and in the more mature cell populations, T-lymphocytes, B-lymphocytes and myeloid cells (CD3+, CD19+ and CD33+ cells) in blood. LÄS MER

  7. 5. Investigation of flux dependence on viscosity in ultrafiltration

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Peter Bourghardt; [2023]
    Nyckelord :ultrafiltration; viscosity; molasess; konjac glucomannan; comsol; LabStak M39; membrane; filtration; chemical engineering; Chemistry;

    Sammanfattning : This project aims to compare the effect of viscosity on flux for high viscosity liquids. The performance of two different viscous solutions was studied in a plate-and-frame membrane module. LÄS MER
