  1. 1. Evaluation of AI-method for measuring and characterizing particles on-line in drinking water treatment

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lovisa Ådén; [2023]
    Nyckelord :Turbidimeter; Particle meter; rapid filtration;

    Sammanfattning : The municipal association Norrvatten produces drinking water at Görväln WTP for approximately 700,000 residents in 14 member municipalities in the northern Stockholm region. To ensure the drinking water meets quality criteria, the water must be carefully monitored by the WTP. LÄS MER

  3. 2. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

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

    Författare :Honorine Uwera; [2020]
    Nyckelord :turbidity; suspended sediments; dissolved organic matter; optical measurements;

    Sammanfattning : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). LÄS MER

  4. 3. Do Clay Minerals affect the thickener operationin Chuquicamata mine, Calama, Chile?

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Chris Soto; [2020]
    Nyckelord :Mine; clay minerals; mineral processing;

    Sammanfattning : Chuquicamata mine mineralogy has been studied performing both X-Ray Diffraction (XRD) and X-RayFluorescence (XRF) to determine whether there is any influence in the thickener operations. Thetargeted minerals were the clay group because of their detrimental effect on mining operations asmodify the rheology of the suspensions. LÄS MER

  5. 4. Påverkan av Asellus aquaticus (sötvattensgråsugga) på resuspension av partiklar i våtmarker

    Kandidat-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Agnes Ekman Söderholm; [2011]
    Nyckelord :Asellus aquaticus; bioturbation; particles; resuspension; sediment; wetlands; Asellus aquaticus; bioturbation; partiklar; resuspension; sediment; våtmarker;

    Sammanfattning : Anlagda våtmarker i avrinningsområden från jordbruksmarker mottar ofta vatten med höga halter av partikelbunden fosfor. Den viktigaste processen för avskiljning av inkommande partikelbunden fosfor är sedimentation. LÄS MER

  7. 5. Aggregatstabilitet, jordbearbetning och fosforförluster i ett typområde på jordbruksmark

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Anna Melakari; [2005]
    Nyckelord :aggregatstabilitet; jordbearbetning; fosforförluster; jordbruksmark;

    Sammanfattning : Large amounts of phosphorus (P) are lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. LÄS MER
