  1. 1. 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

  3. 2. Dynamic Control, Modeling and Sizing of Hybrid Power Plants : Investigating the optimum usage of energy storage for Fortum’s hydropower

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Klas Lindgren; [2023]
    Nyckelord :Hydropower Plants; Energy Storage Systems; Hybrid Units; Frequency Regulation; Modeling; XGBoost Regression; Vattenkraftverk; Energilagringsystem; Hybridkraftverk; Frekvensreglering; Modellering; XGBoost Regression;

    Sammanfattning : The rapidly evolving Nordic Power System demands enhanced flexibility and robustness in electricity production. The traditional role of hydropower plants in regulating the grid frequency has been challenged by new criteria for dynamic stability, which some units struggle to meet due to their relatively poor dynamic performance.

  4. 3. Evaluating the feasibility of implementing ecological flows at Fridafors Hydropower plant

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Michelle Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : Sweden’s almost 2200 hydropower plants and their attached dams are going to be re-licensed with regards to the new environmental legislations made by the government and EU’s water framework directive. As a solution to restore and improve the health of the Swedish riverine systems, a number of different mitigation measures are suggested. LÄS MER

  5. 4. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

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

    Författare :Eddie Blomström; [2022]
    Nyckelord :fishway; flow; hydraulics; HEC-RAS;

    Sammanfattning : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. LÄS MER

  7. 5. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Virginia Tosi; [2021]
    Nyckelord :Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Sammanfattning : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.
