  1. 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; 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

  2. 2. Coupled Hydrological and Microbiological Processes Controlling Denitrification in Constructed Wetlands

    Author : Johan Kjellin; Anders Wörman; Sara Hallin; Barbro Ulén; Björn Klöve; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Constructed wetland; Residence time; water flow modeling; denitrification rate; Tracer experiment; denitrifying bacteria community structure; Water in nature and society; Vatten i natur och samhälle;

    Abstract : Treatment wetlands play an important role in reducing nitrogen content in wastewater and agricultural run-off water. The main removal process is denitrification and the removal efficiency depends on the hydrological and microbiological features of the wetland, especially in terms of water residence times and denitrification rates.

  3. 3. Industrial by-products in treatment of metals from polluted water

    Author : Emma Nehrenheim; Lars Wester; Björn Klöve; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landfill leachate; water treatment; low cost sorbent; pine bark; field study; batch experiments; Environmental engineering; Miljöteknik;

    Abstract : Water treatment can be carried out effectively by passive, low cost methods, as an addition or alternative to existing advanced technology. Energy and resource use can be optimized (i.e. minimized) by reusing by-products from local or regional manufacturing of timber and steel. READ MORE

  4. 4. On-site wastewater treatment : Polonite and other filter materials for removal of metals, nitrogen and phosphorus

    Author : Agnieszka Renman; Per-Erik Jansson; Lars D. Hylander; Gunno Renman; Björn Klöve; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkaline materials; heavy metals; mechanisms; nutrient removal; sorption; speciation modelling; Environmental engineering; Miljöteknik;

    Abstract : Bed filters using reactive materials are an emerging technology for on-site wastewater treatment. Chemical reactions transfer contaminants from the aqueous to the solid phase. Phosphorus is removed from domestic wastewater by sorption to filter materials, which can then be recycled to agriculture as fertilisers and soil amendments. READ MORE
