  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. Modelling Micropollutant Removal Through Ozonation in Wastewater

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maximiliano Andrés Oportus Foster; [2023]
    Nyckelord :Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. LÄS MER

  4. 3. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Amanda Carlund; [2023]
    Nyckelord :;

    Sammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER

  5. 4. BSF-colony management efficiency at a large scale fly larvae composting company in Kenya – A field study

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hilda Anderberg; [2023]
    Nyckelord :Black soldier fly composting; BSF-colony; industrial scale; parasitic wasps; Amerikansk vapenfluga; fluglarvskompostering; storskaligt; parasitsteklar;

    Sammanfattning : The majority of organic waste globally is either dumped or placed on landfills, which can result in spreading of disease and pests, methane gas emissions, the deterioration of landscapes and odour pollution. One of the solutions to poor organic waste management is to create value from waste. LÄS MER

  7. 5. Värme från gruvvatten : En undersökning av olika metoder för att kunna hämta värme ur vattnet som pumpas upp ur gruvorna

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Glas Mathilda; [2023]
    Nyckelord :gruvvatten; värmepump; värmeväxlare; kollektor;

    Sammanfattning : Boliden Mineral AB - Boliden Mines is a company that carries out continuous improvement work in the energy and environmental area. During this degree project, the possibility of making use of waste heat from the mine water that is pumped out of the Renström mine was evaluated. LÄS MER
