  1. 16. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anna Träff; [2022]
    Nyckelord :Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

    Sammanfattning : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. LÄS MER
