  1. 1. Floating treatment wetlands for stormwater management : Plant species selection and influence of external factors for heavy metal and chloride removal in a cold climate

    Författare :Maria Schück; Maria Greger; Hans Brix; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Floating treatment wetlands; Phytodesalination; Rhizofiltration; Phytoremediation; Stormwater; Heavy metals; Chloride; Plant traits; Carex riparia; Carex pseudocyperus; Phalaris arundinacea; Flytande våtmarker; dagvatten; tungmetaller; klorid; fytoremediering; slokstarr; rörflen; jättestarr; växtfysiologi; Plant Physiology;

    Sammanfattning : Stormwater, which consists of rainwater and snowmelt, often contains pollutants from vehicle traffic, building materials, and industries. These pollutants include chloride and heavy metals, which can cause several environmental issues, such as being toxic to biota at elevated concentrations. LÄS MER

  2. 2. Components for area-efficient stormwater treatment systems

    Författare :Ivan Milovanovic; Annelie Hedström; Inga Herrmann; Jovan Despotovic; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater; VA-teknik; Urban Water Engineering;

    Sammanfattning : With progressing urbanisation, treatment of urban stormwater is a vital issue that should be addressed to ensure good water quality in receiving water bodies. Treatment may be performed near the source, with different filter systems using various filter materials, or by using an end-of-pipe method, e.g. a stormwater pond. LÄS MER

  3. 3. Watershed-based design of stormwater treatment facilities : model development and applications

    Författare :Thomas Larm; KTH; []
    Nyckelord :watershed; stormwater; runoff; pollutant transport; design criteria; constructed wetland; wet pond; filter strip; swale; reduction efficiency; monitoring program; StormTac;

  4. 4. Stormwater Ponds for Pollution Reduction

    Författare :Thomas Pettersson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; suspended solids; reduction; pollution; stormwater pond; flow modelling; FEM; field measurements; heavy metals; nutrients;

    Sammanfattning : Stormwater transports particulate-bound and soluble pollution from urban areas to receiving waters during rain events. Measurements have shown that open detention ponds, originally used for flood control, effectively reduce stormwater pollutant load and have therefore been increasingly used for stormwater treatment.

  5. 5. Reducing Stormwater Pollution - Performance of Retention Ponds and Street Sweeping

    Författare :Jonas German; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban runoff; street sweeping; removal processes; treatment; removal efficiency; sediment; stormwater; BMP; modelling; pond;

    Sammanfattning : Stormwater, in this study defined as surface runoff in urban areas, is known to transport large quantities of toxic substances to receiving waters. Therefore different practices to treat stormwater have been proposed. In Sweden retention ponds have become a common treatment method during the past decade. LÄS MER
