  1. 16. Urban Stormwater Treatment with Ultrafiltration and Pulsatile Fluid Flow

    Författare :Saida Kaykhaii; Inga Herrmann; Annelie Hedström; Ekaterina Sokolova; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : Stormwater can be a potential water resource if it is treated, and the quality meets the demand, depending on the application. Various nutrients and pollutants, for example microorganisms can enter stormwater and can vary depending on time and place, as the contaminants come from different sources. LÄS MER

  3. 17. Generation of urban runoff : Seasonal and climate change perspective

    Författare :Shahab Moghadas; Claes Hernebring; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Runoff generation in cold regions is characterized by snowmelt contributions to runoff during the periods of thawing and changing runoff patterns due to frozen ground. This thesis project aimed at addressing these challenges by advancing the procedures for winter urban runoff computations and the assessment of control measures during the winter/spring period, when the snowmelt and frozen soils dominantly impact runoff generation in the current and future climates.

  4. 18. An evaluation of sources contributing to urban runoff pollution

    Författare :Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER

  5. 19. 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.
