1. Techno-Economic Analysis of Dye Separation in Textile Recycling
Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresursläraSammanfattning : 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
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 ekonomiSammanfattning : 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
3. Effekten av flyktiga fettsyror (VFA) på tillväxten av mikroalger
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : 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
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 teknikSammanfattning : 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
