  1. 1. Evaluation of The Viral Reduction Potential using Ultrafiltration Membranes in the Drinking Water Treatment Process at Norrvatten

    Master-uppsats, KTH/Industriell bioteknologi

    Författare :Emma Eriksson; [2023]
    Nyckelord :Microbiological barrier; Ultrafiltration; NanoCeram filter; Drinking Water; Raw Water; Mikrobiologisk barriär; Ultrafiltering; NanoCeram filter; Dricksvatten; Råvatten;

    Sammanfattning : En pilotanläggning för ultrafiltering testas nu i Norrvattens reningsprocess för att undersöka ifall den kan användas som en tredje mikrobiologisk barriär i reningsprocessen. Målet med detta projekt är att testa membranets kapacitet att filtrera bort viruspartiklar men även membranet generella reduktionsförmåga för andra mikrobiologiska och kemiska kontamineringar.

  3. 2. Groundwater flow modelling to address hydrogeological response of a contaminated site to remediation measures at Hjortsberga, southern Sweden

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Adam Johansson; [2020]
    Nyckelord :PCP; Groundwater modelling; Permeable reactive barrier; Hjortsberga sawmill; Earth and Environmental Sciences;

    Sammanfattning : Pentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. LÄS MER

  4. 3. Mapping of Bacteria with Flow Cytometry – before, during and after treatment of drinking water

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Mikael Danielsson; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In order to produce drinking water of high quality, surface water works apply extensive treatment processes. In this study, flow cytometry and heterotrophic plate counting was utilized to study water quality before, during and after treatment in Görvälnverket in Stockholm, Sweden. LÄS MER
