  3. 2. Stormwater Ponds for Pollution Reduction

    Författare :Thomas Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.

  4. 3. When the Rubber Meets the Road -Ecotoxicological Hazard and Risk Assessment of Tire Wear Particles

    Författare :Anna Wik; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tire wear; tire particles; rubber; leaching tests; ecotoxicity tests; Daphnia magna; Ceriodaphnia dubia; Pseudokirchneriella subcapitata; Danio rerio; toxicity identification evaluation; detention ponds; hazard assessment; risk assessment;

    Sammanfattning : Large amounts of rubber particles are dispersed into the environment due to tire wear. The rubber contains a wide range of chemicals, including several of environmental concern. The purpose of this th.. LÄS MER

  7. 5. Three-Dimensional Simulation and Physical Modelling of Flows in Detention Tanks - Studies of Flow Pattern, Residence Time and Sedimentation

    Författare :Åsa Adamsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tracer study; pond; numerical simulation; particle tracking; CFD; bed shear stress; storage tank; stormwater; detention tank; flow pattern;

    Sammanfattning : Improving effluent water quality to receiving waters using stormwater ponds and storage tanks is acknowledged to be an effective method. The performance of the method depends however on flow conditions such as velocity distribution, short-circuiting currents and the volume through which the influent water flows, the so called effective volume.
