1. 11. Nitrifyers in constructed wetlands treating landfill leachates

   Författare :Carina Sundberg; Per-Eric Lindgren; Karin Sundblad-Tonderski; Jenny Stendahl; Hans Brix; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Landfill leachate is produced many years after a landfill site closes. Hence, treatment by “natural methods”, as e.g. constructed wetlands, with low management requirements is attractive. LÄS MER

3. 12. Environmental impact of ashes used in a landfill cover construction

   Författare :Igor Travar; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

   Sammanfattning : The landfilling ban for combustible waste in EU countries and the extended use of bio fuels in heat and electricity production will result in an increasing generation of incineration residues, such as fly ash and bottom ash. Instead of landfilling, ashes used as a construction material in, e.g. LÄS MER

4. 13. Strategy for Monitoring Organic Pollutants in Waste Water with Focus on Improved Sample Preparation

   Författare :Staffan Bergström; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Miljökemi; Environmental chemistry; Analytisk kemi; Analytical chemistry; Membrane extraction; Sample preparation; Organic pollutants; Monitoring strategy; Landfill leachate;

   Sammanfattning : Strategy and methodology is presented for the analysis of organic pollutants, with the purpose of evaluating treatment procedures for landfill leachate. Today, many investigations of treatment procedures are focusing on the measurement of water quality parameters such as chemical and biochemical oxygen demand, (COD and BOD), and total organic carbon, (TOC) when assessing the organic compounds in waste waters.

5. 14. Leaching and Transformation of Flame Retardants and Plasticizers under Simulated Landfill Conditions

   Författare :Maritha Hörsing; Bo H. Svensson; Susanne Jonsson; Anna Karlsson; Cynthia de Wit; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DEHP; BBP; tetrabromobisphenol A; TBBPA; TBBPA-DAE; TBBPA-DBPE; TBBPA-DHEE; Proban; Pyrovatex; Melamine; Environmental chemistry; Miljökemi;

   Sammanfattning : Many products used in our everyday life contain chemicals added to give them specific properties. Flame retardants (FRs) are added to prevent or retard fires in textiles, plastics etc., while plasticizers are supplied to make plastics more flexible. LÄS MER

7. 15. Comparative study on different Anammox systems

   Författare :Grzegorz Cema; Elżbieta Płaza; Joanna Surmacz-Górska; Karl-Heinz Rosenwinkel; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anammox; biofilm system; landfill leachate; nitrogen removal; reject water; removal rates; Environmental engineering; Miljöteknik;

   Sammanfattning : The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements’ removal, in comparison with the past. LÄS MER
