  1. 1. Enhanced Biological Phosphorus Removal -Processes, Competing Substances and Tools for Operation of Wastewater Treatment Plants

    Författare :Eva Tykesson; Vattenförsörjnings- och avloppsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; pollution control; Environmental technology; chemical precipitation; glycogen accumulating organisms; polyphosphate accumulating organisms; wastewater treatment; biological phosphorus removal; kontroll av utsläpp;

    Sammanfattning : The idea of phosphorus removal at wastewater treatment plants is to transfer dissolved phosphorus into a solid phase. Together with the rest of the produced sludge it is then removed from the water, resulting in a decreased concentration of phosphorus in the effluent and the prevention of the eutrophication in the recipient.

  3. 2. Enhanced Biological Phosphorus Removal - Carbon Sources, Nitrate as Electron Acceptor, and Characterisation of the Sludge Community

    Författare :Magnus Christensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge; nitrate; carbon source; PAO; polyphosphate accumulating organisms; enhanced biological phosphorus removal; EBPR; characterisation; Biotechnology; Bioteknik;

    Sammanfattning : Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. LÄS MER

  4. 3. Microbial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems

    Författare :Lydia Ambakisye Mbwele; Gunnel Dalhmmar; Ingrid Faye; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater treatment; waste stabilisation ponds; activated sludge; biological phosphorus removal; tropical climate; A.hydrophylla; Bioengineering; Bioteknik;

    Sammanfattning : Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. LÄS MER

  5. 4. Characterization of Bacterial Biofilms for Wastewater Treatment

    Författare :Sofia Andersson; Gunnel Dalhammar; Bo Mattiasson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biofilm; extracellular polymeric substances; exopolysaccharides; interspecies interactions; wastewater treatment; denitrification; phosphorus removal; Microbiology; Mikrobiologi;

    Sammanfattning : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.

  7. 5. SBR-technology - use and potential applications for treatment of cold wastewater

    Författare :Stig Morling; Elzbieta Plaza; Jörgen Hanaeus; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent operation; Water temperature; nitrogen; phosphorus; SBR; reaction rates; Environmental engineering; Miljöteknik;

    Sammanfattning : Biological nutrient removal is used as an indicator of SBR performance at nine different SBRplants operated for a long period at low water temperatures (5 – 10oC). Typically needed aeratedSRT (Solids Residence Time) for complete nitrification is found to be in the range of 6 – 10 days. LÄS MER
