  1. 1. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

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

    Författare :Abigail Huertas Herrera; [2021]
    Nyckelord :Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Sammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  2. 2. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Bhargav Reddy Elavarthi; [2021]
    Nyckelord :micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. LÄS MER

  3. 3. Relating the impacts of regenerative farming practices to soil health and carbon sequestration on Gotland, Sweden

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Laerke Daverkosen; Alena Holzknecht; [2021]
    Nyckelord :regenerative agriculture; soil health; carbon sequestration; Gotland Sweden ;

    Sammanfattning : Land degradation, greenhouse gas emissions and biodiversity loss through agriculture are some of the greatest challenges we are facing today. Fertile and productive soils are the basis of life on this planet and need to be protected and restored to support a growing population and lower negative impacts of climate change. LÄS MER

  4. 4. Bioekonomin och den biologiska mångfalden : de regionala skogsstrategiernas vägval mellan monetära värden och artrikedom

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Signe Samuelsson Propst; [2021]
    Nyckelord :regionala skogsstrategier; diskursanalys; WPR; biologisk mångfald; biodiversitet; bioekonomi;

    Sammanfattning : Uppsatsen undersöker, med hjälp av diskursanalytisk WPR-metod, hur tre regionala skogsstrategier förhåller sig till mål om biologisk mångfald i relation till det nationella skogsprogrammets vision om en växande bioekonomi. Den biologiska mångfalden framställs i strategierna som något krä-vande, som behöver mycket insatser för att bevaras. LÄS MER

  5. 5. Modeling wind-induced currents in lake Bolmen, Sweden, using TELEMAC 2D

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Prasanjaya Bandara Ekanayake; [2021]
    Nyckelord :Bolmen Lake; TELEMAC 2D; Wind induced currents; QGIS; Blue Kenue; Technology and Engineering;

    Sammanfattning : Transport and material intermixing within lake systems have a significant impact on lake water quality. However, since researchers are primarily concerned with biological, environmental, and ecological aspects, physics and hydrodynamic behavior in lake water currents frequently receive less attention.
