  2. 1. Environmental impact of peat mining : Development of storm water treatment methods

    Author : Bjørn Kløve; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; drainage artificial floodplaines; phosphorus; suspended solids; nitrogen; erosion; peat mining; peak runoff controll; sedimentation; water treatment; water resources; hydrology; hydraulics; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. READ MORE

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

    Author : Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
    Keywords : 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 ;

    Abstract : 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. READ MORE

  5. 3. Inhibition of Nitrification in Municipal Wastewater - Sources, Effects, Evaluation and Remedies

    Author : Karin Jönsson; Vattenförsörjnings- och avloppsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Wastewater; Toxicity; Nitrification; Inhibition; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. READ MORE

  6. 4. Future trends in urban stormwater quality : effects of changes in climate, catchment characteristics and processes and socio-economic factors

    Author : Matthias Borris; Lian Lundy; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Climate change and progressing urbanization cause numerous environmental concerns, including the impacts on urban drainage. Such impacts were addressed during the last two decades with focus on hydraulic overloading of drainage systems and the means of overload remediation by stormwater management. READ MORE

  7. 5. Biotechnological treatment of chlorophenol-contaminated water

    Author : Hamid Zilouei; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; Bioteknik; kontroll av utsläpp; Miljöteknik; pollution control; Environmental technology; Cell-based biosensor; Fluorescence in situ hybridization; Bacterial community; Two-liquid phase partitioning bioreactor; Photolysis pretreatment; Biomonitoring; Fixed-biofilm reactors; Toxic organic pollutant; Biodegradation;

    Abstract : Widespread presence of toxic and persistent pollutants in the environment, even at low concentrations, causes risks of adverse effects to human health and the ecosystem. Biological methods for treatment of water streams and removal of persistent pollutants are of great interest due to their simplicity, low cost, and mild operational conditions without harmful by-products.
