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

    Author : Emma Nehrenheim; Lars Wester; Björn Klöve; Mälardalens högskola; []
    Keywords : 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. 7. Role of soil organic matter for immobilisation of metals : treatment of leachate from MSWI bottom ashes

    Author : Jurate Kumpiene; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : In this thesis, the focus is laid on the ability of natural organic matter (OM) to serve as a metal stabilising agent. The metal contaminants investigated arise from the MSWI bottom ash leachate. Besides the high content of metals, elevated pH and salinity are characteristic for ash leachate that, in turn, can alter the functionality of OM. READ MORE

  5. 8. Modern landfill leachates – quality and treatment

    Author : Hanna Modin; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heavy metals; European Landfill Directive; Biodegradation; Landfill leachate; Leaching tests; Multivariate data analysis; Organic matter; Sorption filters;

    Abstract : Waste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. READ MORE

  6. 9. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry

    Author : Henric Svensson; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood leachate; Log yard runoff; Stormwater; Toxicity; Artemia salina; Vibrio fischeri; Constructed wetlands; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials.

  7. 10. Use of chemical denitrification for nitrogen removal from landfill leachates

    Author : Aleksandra Nikolic; KTH; []
    Keywords : Chemical denitrification; conductivity; evaporation drying; freezing thawing; leachate; nitrogen removal;

    Abstract : Landfill leachate usually has a high concentration ofammonium nitrogen and heavy metals, but too low alkalinitycontent for full biological nitrification, as well as a too lowconcentration of biologically degradable organic carbon forbiological denitrification, and at the same time very variablecomposition (quantity and quality) with time. These factorsresult in serious problems for treating leachate with existingsystems. READ MORE
