  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. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

    Författare :Ryoi Takamatsu; [2023]
    Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

  4. 3. Effekten av flyktiga fettsyror (VFA) på tillväxten av mikroalger

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Raghad Kattan; Lina Kaakeh; [2023]
    Nyckelord :Mikroalger; anaerob jäsning; VFA; avloppsvatten;

    Sammanfattning : Anaerob jäsning antas vara en bra och effektiv metod för behandling av organiskt avfall. Avloppsvatten från denna process är mer utmanande beroende främst på dess höga innehåll av bland annat flyktiga fettsyror (VFA). LÄS MER

  5. 4. DEVELOPING METHODS FOR WATER QUALITY MEASUREMENT : Using machine learning and remote sensing to predict absorbance with multispectral imaging

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Ola Bratt; [2023]
    Nyckelord :Remote Sensing; Multivariate Analysis; Machine Learning; GIS; Spectroscopy; Spectral imaging; Multispectral imaging; Water Quality;

    Sammanfattning : Water resources play an important role in society and fulfill various functions such as providing drinking water, supporting industrial production and enhancing the overall landscape. Water bodies, such as rivers and lakes, are particularly important in this context. LÄS MER

  7. 5. Dioxins: An Easy Problem to Solve or a Hard-Fought Battle for the Environment? a Case Study of How and Why the Pulp and Paper Industry in Sweden Transitioned Away From Chlorine-Bleaching

    Master-uppsats, Lunds universitet/Sociologiska institutionen; Lunds universitet/Sociologi

    Författare :Marcus Aronsson; [2023]
    Nyckelord :environmental sociology; ecological modernization; treadmill of production; middle-range; industrial transition; Social Sciences;

    Sammanfattning : The situation for the environment is in many ways dire. However, amidst all the negative environmental developments it is easy to neglect the successes that have actually happened. LÄS MER
