1. 1. Möjligheten att minska metallhalten i lakvatten med sulfatreducerande bakterier

   Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

   Författare :Sofie Sunesson; [2020]
   Nyckelord :Metals; Landfill; Leachate; SRB; Precipitation; Sulfide; Applied microbiology; Teknisk mikrobiologi; Earth and Environmental Sciences; Technology and Engineering;

   Sammanfattning : Anaerobic treatment of landfill leachate using sulphide precipitation was tested at pilot scale for the purpose of heavy metal removal. The emission of leachate is heavily regulated by Swedish authority and the overall concentrations of heavy metals is expected to rise as landfills contain less organic matter. LÄS MER

3. 2. Fate of Heavy Metals in Waste to Energy (WtE) Processes

   Kandidat-uppsats, KTH/Skolan för kemivetenskap (CHE)

   Författare :Ninus Chamoun; Viktor Kjellvertz; William Mahajan; Yuanchao Song; [2016]
   Nyckelord :Wastewater treatment; Removal of heavy metals; Precipitation; Condensate treatment; Modelling with PHREEQC and Medusa;

   Sammanfattning : This study was made to increase the understanding of how heavy metals in the aqueous phase are removed at low initial concentrations in different pH and Eh values. The reaction that has been studied is mainly hydroxide precipitation and adsorption in a condensate treatment. LÄS MER

4. 3. Arsenic Removal From Flue Gas Condensate with Ferrihydrite Precipitation.

   Master-uppsats, KTH/Mark- och vattenteknik

   Författare :Louise Waldenström; [2014]
   Nyckelord :Waste wood; Pressure-treated wood; Flue gas condensate; Arsenic removal by precipitation; Ferrihydrite; TMT 15;

   Sammanfattning : At the Idbäcken combined heat and power (CHP) plant waste wood is combusted. The flue gas from the combustion is condensed and heavy metals and other toxic species ends up in the condensate water. LÄS MER
