    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sofia Mile; [2023]
    Keywords : Chemical Engineering; Water and Environmental Engineering; Water Treatment; Coagulation Flocculation; Sludge Recirculation; Technology and Engineering;

    Abstract : Drinking water is crucial in our everyday life. As with many other processes, it is important to produce water of drinking quality in a sustainable manner. This can occur by e.g. READ MORE

  3. 2. How brownification and eutrophication effects a drinking water source – with Lake Bolmen, Sweden, in focus

    University essay from Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Stina Stomberg; [2022]
    Keywords : brownification; eutrophication effects; drinking water; phytoplankton; Lake Bolmen; mesocosm; Earth and Environmental Sciences;

    Abstract : The ongoing human impact in form of deforestation, urbanization and intense agriculture is affecting the natural hydrology and our freshwater lakes negatively. Both eutrophication and brownification has seen to increase with the ongoing environmental change which can potentially have large impact on our freshwater ecosystems. READ MORE

  4. 3. Greenhouse gas emissions from three large lakes during the autumn 2020

    University essay from Linköpings universitet/Institutionen för tema

    Author : Veronica Bohlin; Anja Anderö Nordqvist; [2021]
    Keywords : methane; carbon dioxide; dissolved inorganic carbon; pCO2; flux chambers; large lakes; methane budget; carbon budget; GHGs; freshwater; spatiotemporal; ebullition; diffusion; autumn; metan; koldioxid; upplöst oorganiskt kol; pCO2; kammarmetod; stora sjöar; metanbudget; koldioxidbudget; växthusgaser; sötvatten; spatiotemporal; ebullition; diffusion; höst;

    Abstract : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. READ MORE

  5. 4. Minskat fosforläckage från hästhagar : utvärdering av mockning som åtgärd och hästhållares syn på åtgärdsarbete för miljön

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sofia Nyström; [2021]
    Keywords : hästgödsel; näringsläckage; rasthagar; fosforläckage; häst; övergödning; Östersjön; mockning;

    Abstract : Östersjön är kraftigt påverkad av övergödning, som beror på att en för stor mängd näringsämnen tillförs havet. Övergödande ämnena kväve och fosfor kommer framför allt från våra jordbruksmarker och förs via urlakning och ytavrinning vidare till våra sjöar, vattendrag och till slut Östersjön. READ MORE

  6. 5. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sanna Sahlin; [2021]
    Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE
