  4. 2. Coagulation process characteristics and pollutant removal from urban runoff

    Author : Fredrik Nyström; Inga Herrmann; Annelie Hedström; Maria Viklander; Michael Cimbritz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stormwater; urban snowmelt; road runoff; coagulation flocculation sedimentation; coagulation characteristics; coagulation mechanism; treatment efficiency; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Abstract : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies.  The treatment function of  SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles.

  5. 3. Contribution of stormwater ponds for road runoff to aquatic biodiversity

    Author : Zhenhua Sun; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; road salt; stormwater ponds; water quality; sediments; road runoff; metals; pond size; aquatic biodiversity;

    Abstract : The increased recognition that roads may impair the aquatic environment and ecosystems has led to a shift from conventional drainage systems toward blue-green solutions such as stormwater ponds. Research on blue-green stormwater solutions has until now mainly focused on water quantity and quality. READ MORE

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

    Author : Jonas German; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; urban runoff; street sweeping; removal processes; treatment; removal efficiency; sediment; stormwater; BMP; modelling; pond;

    Abstract : 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. READ MORE

  7. 5. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies

    Author : Anna Markiewicz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic pollutants; nanoparticles; stormwater; sorption filters; road dust; emulsions; washwater; vehicle wash; road runoff; microparticles; sweepsand; colloids; street sweeping;

    Abstract : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. READ MORE
