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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  3. 2. Ultrasonication of Spiral Wound Membranes to Mitigate Fouling in Reverse Osmosis

    University essay from KTH/Kemiteknik

    Author : Eliot Diklev; [2022]
    Keywords : Reverse Osmosis; Spiral Wound Membrane; Ultrasonication; Fouling; Omvänd Osmos; Spirallindat Membran; Ultraljudsbehandling; Igenslamning;

    Abstract : Syftet med den här studien var att undersöka en alternativ slamningsreducerande teknik till spolning, som effektivt kan ta bort biologisk påväxt. Ultraljud undersöktes som en möjlig metod för att ta bort igenslamningen från omvänd osmos med ett spirallindat membran. READ MORE

  4. 3. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnéa Petersson; [2020]
    Keywords : QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. READ MORE

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

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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). READ MORE

  6. 5. Integrating membrane filtration forwater reuse in tissue mill

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Ehsan Moslehi; [2018]
    Keywords : Membrane separation; Paper industry; Paper mill effluent; Water reuse ; Reverse Osmosis;

    Abstract : Water is an essential and indispensable component is the pulp- and paper production industry.The increase in energy costs, stricter environmental regulations and water resource shortageshave caused a reduction of the water footprint in the industry as well as an increase in waterrecycling and water circuit closure.
