  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. Utilization of Biomethane in Decarbonising India´s Energy Mix

    Master-uppsats, KTH/Energiteknik

    Författare :Niraj Ravindra Kunkulol; [2023]
    Nyckelord :Anaerobic digestion; biogas; biomethane; membrane filtration; pressure swing adsorption; Anaerob rötning; biogas; biometan; membranfiltrering; trycksvängadsorption;

    Sammanfattning : This thesis investigates the potential of biomethane production in India, the impact of its integration into the energy mix, and the corresponding Greenhouse Gases (GHG) emission and potential reduction. India, with its huge population and being an agriculturally rich country, produces gigantic amounts of biodegradable waste from various sources such as Municipal Solid Waste (MSW),agricultural waste, animal husbandry, sugar industry, etc. LÄS MER

  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. 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

  7. 5. Platelet function after storage in leukocyte : reduced whole blood and preheating to 37°C

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Alma Bolmsvik; Sofia Bjelkvik; [2023]
    Nyckelord :Blood platelets; blood transfusion; flow cytometry; blood cell count; platelet membrane glycoproteins; platelet activation.;

    Sammanfattning : Introduction: Whole blood transfusions are indicated for the resuscitation of patients with hemorrhagic trauma. In Sweden, whole blood is stored for 14 days at 4°C. If possible, refrigerated blood is rewarmed to 37°C before transfusion to avoid hypothermia. Platelets contribute to hemostasis and can be activated with several pathways. LÄS MER
