  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. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Martin Åsell; [2024]
    Keywords : Inflow and Infiltration; I I; CNN; Linear regression;

    Abstract : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. READ MORE

  4. 3. Kvillebäcken : analys och gestaltningsförslag - me[d]andra strukturer och processer

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Louise Stigsson Rigné; Emil Vernersson; [2024]
    Keywords : Urbanekologi; landskapsarkitektur; hydrologi; vattendrag; naturbaserade lösningar; blågrön infrastruktur;

    Abstract : I byggandet av hållbara städer är utveckling av blågrön infrastruktur högaktuell, och inom detta faller stort fokus på utveckling av urbana vattendrags ekologi, vattenkvalitet, och förmåga att omhänderta konsekvenser av klimatförändringar. Få vattendrag uppnår miljökvalitetsnormerna, och platsspecifika utmaningar finns i varje vattendrag. READ MORE

  5. 4. Invasive plant species in southwest Sweden: Evaluation methods of removal by empirical study and literature review

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Carl-Johan Dekker; [2023-08-07]
    Keywords : Invasive alien species; management; nature conservation; biodiversity;

    Abstract : Invasive alien species (IAS), are one of the five biggest threats to biodiversity worldwide. An instrument for biodiversity protection in Sweden is the establishment and management of nature reserves. The goal of nature reserves is to protect valuable nature and rare species to preserve biodiversity. READ MORE

  6. 5. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dominika Kiesling; [2023]
    Keywords : oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Abstract : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.
