  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. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  4. 3. Influence of supercritical carbon dioxide (scco2) dyeing parameters on color fastness of polyester fabric dyed with disperse dye : A study towards minimizing the energy consumption of polyester (pet) fabric dyeing with azo disperse dye

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

    Author : Tapas Das; [2023]
    Keywords : Supercritical fluid dyeing; polyester PET fabric; coranger orange PE3330; color fastness; ideal dyeing conditions; eco-friendly;

    Abstract : Amid growing environmental concern and continuous depletion of natural resources (such as water), the textile industry is constantly searching for sustainable production process. Traditional dyeing processes, notorious for their enormous water consumption, have led society to search alternative dyeing method. READ MORE

  5. 4. Wastewater Treatment at Kraft Pulp Mills : Effect of temporary effluents and mitigation measures

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Hodda Shariatmadari; [2023]
    Keywords : ;

    Abstract : Large amount of water is used in the pulp-and-paper industry. Consequently, large amount of wastewater is produced in the various production processes. In general, the pollutants of concern involve organic compounds, nutrients, including nitrogen and phosphorous, suspended solids, and chlorinated compounds. READ MORE

  6. 5. Using microalgae for removing nutrients from RAS aquaculture effluents - a viable strategy? A case study.

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Samuel Karlsson; [2022-07-06]
    Keywords : ;

    Abstract : The increased global demand for fish has caused a tremendous increase in aquaculture production during the last decade, emphasising the importance of systems with a low climate footprint. One such system is a recirculating aquaculture system (RAS) which is land-based as opposed to traditional open systems. READ MORE
