  1. 1. Fluorescence probes: towards automatic coagulant dosing

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

    Författare :Daphné Lecellier; [2018]
    Nyckelord :Drinking water quality; Water treatment process; Coagulation; Microcystis aerugosa; algal organic matter; LC-OCD; EEM; powdered activated carbon; Alum;

    Sammanfattning : There is a current lack of accurate tools to determine the concentration of cyanobacteria in situ.  Besides, cyanobacterial blooms have to be carefully monitored in reservoirs as they are more frequent because of climate change and can lead to potential released of toxins, along with other components.

  3. 2. Application of 2D fluorescence spectroscopy on faecal pigments in water : characterization of wastewater fluorescence and potential indication of faecal pollution

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Bärbel Daub; [2017]
    Nyckelord :wastewater; faecal pollution; faecal pigment; fluorescence; urobilin; stercobilin;

    Sammanfattning : Drinking water pollution by faeces and associated enteric pathogens can cause serious health issues and outbreaks of diseases. A fast and reliable indication of faecal pollution is necessary to prevent the consumption of polluted water. LÄS MER

  4. 3. Organic matter properties and their relation to phosphorus and nitrogen concentrations in Swedish agricultural streams

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

    Författare :Betty Ehnvall; [2017]
    Nyckelord :dissolved organic matter; excitation-emission fluorescence spectroscopy; absorbance spectroscopy; eutrophication; biogeochemistry; absorbance index; fluorescence index;

    Sammanfattning : Many agricultural streams in Sweden exhibit high concentrations of nitrogen, phosphorus, suspended sediments and dissolved organic matter (DOM). Together these substances cause eutrophication in streams, rivers and eventually the Baltic Sea. The interactions between different fractions of DOM and nutrients are not very well understood. LÄS MER
