  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

  2. 2. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Hana Faulds; [2023]
    Keywords : Cyanobacteria; pigments; microalgae; wastewater treatment; biotechnology; Technology and Engineering; Biology and Life Sciences;

    Abstract : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

  3. 3. Finding ways of optimizing coagulant dosage, for a more sustainable wastewater treatment process

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Hanna Sjöman; [2023]
    Keywords : Wastewater treatment process; coagulant dosage; COD; machine learning; water and environmental engineering; Technology and Engineering;

    Abstract : The wastewater treatment process at Oatly consists of several treatment steps of which, two are chemical treatment steps involving coagulation followed by flotation to remove phosphorous and COD. The coagulant dosage is mainly determined based on the operator’s experience and supported using results from jar tests. READ MORE

    Abstract : Freshwater scarcity leads to serious effects on the socioeconomic and commercial development of a country. The management of freshwater resources will be one of the most pressing issues of this millennium making it a catalyst for war and peace. READ MORE

  5. 5. IMPLEMENTATION OF NITROGEN RECOVERY AT WASTEWATER TREATMENT PLANTS TO COMPLEMENT ARTIFICIAL FERTILISER PRODUCTION : An investigation of the nitrogen recovery potential, energy consumption and environmental impacts at Kungsängens wastewater treatment plant in Västerås, Sweden

    University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Author : Cassandra Kestran; Olivia Larsson; [2023]
    Keywords : Ammonia stripping; Eutrophication; Fertiliser production; Gas permeable membrane; Haber-Bosch; Nitrogen management; Nitrogen recovery technologies; Nitrogen removal; Reject water;

    Abstract : As Kungsängens wastewater treatment plant is considering a move, it opens up a possibility to implement nitrogen recovery technologies that comply with current and future legislative requirements. Nitrogen recovery offers simultaneous treatment of wastewater and collection of concentrated ammonia products for fertiliser production. READ MORE
