  1. 6. Wastewater treatment in constructed wetlands Effects of vegetation, hydraulics and data analysis methods

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Hristina Bodin; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; constructed wetland; free water surface flow; wastewater treatment; Kenya; Sweden; vegetation; harvest; Cyperus papyrus; Echinochloa pyramidalis; mass load; phosphorus; ammonium; suspended solids; pollutant removal; hydraulics; residence time distribution; data analysis methods; Konstgjorda våtmarker; avloppsvatten; vattenrening; fosfor; ammonium; partiklar; Kenya; Sverige; växter; Cyperus papyrus; Echinochloa pyramidalis; skörd; hydraulik; dataanalysmetod;

    Sammanfattning : Degradation of water resources has become one of the most pressing global concerns currently facing mankind. Constructed Wetlands (CWs) represent a concept to combat deterioration of water resources by acting as buffers between wastewater and receiving water bodies. LÄS MER

  2. 7. Antibiotic Resistance in Wastewater Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Stefan Börjesson; Linköpings universitet.; Linköpings universitet.; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MRSA; SCCmec; spa typing; Staphylococcus aureus; methicillin; B-lactam; aminoglycoside; tetracycline; antibiotic; wastewater; wastewater treatment plant; NATURAL SCIENCES Biology Organism biology Microbiology; NATURVETENSKAP Biologi Organismbiologi Mikrobiologi;

    Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER

  3. 8. Application of magnetic nanoparticles and reactive filter materials for wastewater treatment

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reactive filter materials; magnetic nanoparticles; wastewater treatment process; nutrient reduction; sludge water content; toxicity of magnetic nanoparticles;

    Sammanfattning : Lately sewage wastewater treatment processes (WWTP) are facing challenges due to strict regulations in quality of effluent standards and waste production. The reuse of wastewater treatment effluents is rapidly gaining attention as a means of achieving sustainable water supply. Therefore, new methods are required to achieve an efficient WWTP. LÄS MER

  4. 9. Anammox-based systems for nitrogen removal from mainstream municipal wastewater

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Andriy Malovanyy; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wastewater; Nitrogen removal; Ion exchange; Deammonification; Anammox; Mainstream; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Nitrogen removal from municipal wastewater with the application of deammonification process offers an operational cost reduction, especially if it is combined with a maximal use of organic content of wastewater for biogas production. In this thesis, two approaches for integration of the deammonification process into the municipal wastewater treatment scheme were studied. LÄS MER

  5. 10. Anaerobic digestion in the kraft pulp and paper industry Challenges and possibilities for implementation

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Eva-Maria Ekstrand; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulp and paper; anaerobic digestion; fibre sludge; activated sludge; condensates; bleaching wastewater; wastewater treatment; methane; degradability; nutrient recirculation; Pappers- och massa; anaerob nedbrytning; fiberslam; aktivt slam; kondensat; vattenrening; metan; nedbrytbarhet; näringsåterföring;

    Sammanfattning : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.
