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

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Fiber- och polymerteknologi

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

    Abstract : 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

    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

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  6. 5. Competition between Phase Separation and Micellization in a Coarse-Grained Protein Model with Two Components

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Fangxuan Lyu; [2022]
    Keywords : Physics and Astronomy;

    Abstract : Intrinsically disordered proteins (IDPs) are widely believed to play a key role in the for- mation of intracellular biomolecular condensates through liquid-liquid phase separation (LLPS). Furthermore, it has been shown in vitro that several IDPs are able to phase sepa- rate on their own. READ MORE
