  1. 1. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

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

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  3. 2. Treatment of Metals in Highway Runoff Water : Comparison of green infrastructures and filter material for stormwater treatment

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

    Författare :Fanny von Matérn; [2023]
    Nyckelord :Road runoff; heavy metals; constructed wetland; stormwater pond; vegetated filterstrip; vegetated swale; sandfilter; reactive filter material; Vägdagvatten; tungmetaller; anlagd våtmark; dagvattendam; översilningsyta; svackdike; sandfilter; reaktiva filtermaterial;

    Sammanfattning : Highway runoff transport high concentrations of heavy metals. As climate change affect the environment with for example increased storm events, the treatment of road runoff becomes more important. LÄS MER

  4. 3. Treatment of dissolved metals in highway runoff water : Pilot-scale trial with four reactive filter media and sand filter

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

    Författare :Serena Bianchi; [2021]
    Nyckelord :stormwater treatment; metal removal; adsorption; reactive filter media; sand filtration; Petrit-T; Polonite; D-Rainclean; Filtralite-P; de-icing salt; pressure drop; filter clogging; rening av dagvatten; avl ̈agsnande av metaller; adsorption; reaktiva filterme- dier; sandfiltrering; Petrit-T; Polonite; D-Rainclean; Filtralite-P; avisningssalt; tryckfall; filterstoppning;

    Sammanfattning : The increasing highway traffic is leading to higher and higher levels of pollutants in the stormwater, such as suspended solids, metals, oils, nutrients and PAH. This runoff water causes the degradation of water bodies quality, leading to increased interest in the treatment of highway runoff for the removal of contaminants. LÄS MER

  5. 4. Treatment of wash water from road tunnels.

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Lina Byman; [2012]
    Nyckelord :tunnel wash; wash water; water treatment; sedimentation; total suspended solids; highway runoff;

    Sammanfattning : Tunnels have become increasingly important in the development of road networks to meet rising transportation demands. Washing of road tunnels must be performed regularly to ensure traffic safety. The washing procedure generates significant amount of polluted wash water. LÄS MER

  7. 5. A preliminary work on highway runoff treatment design in Shanghai

    Magister-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :XIAO WANG; [2010]
    Nyckelord :highway runoff; constructed wetland; BMPs;

    Sammanfattning :  As highway runoff is one major source of non-point pollution in urban areas, removal of contaminants in runoff should be of great concern. In this paper, the necessity of highway runoff treatment in Shanghai was approved, systemic comparisons between runoff treatments were listed, detailed discussions on treatment approach selection were given based upon the availability of land.
