  4. 3. Pathways of pollutants in stormwater systems

    Författare :Kristin Karlsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : The choice of stormwater procedures will affect the pathways of the water and its pollutants, since different stormwater facilities reduce different types of substances and fractions to varying degrees. Traditional stormwater handling has mainly been emphasised to transport the water from the cities. LÄS MER
