  1. 16. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies

    Författare :Magda Wilewska-Bien; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; washing; filtration; MSW; cyclone ash; : leaching; fly ash; MSWI ash;

    Sammanfattning : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. LÄS MER

  3. 17. Humidification Processes in Gas Turbine Cycles

    Författare :Marcus Thern; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; applied thermodynamics; Thermal engineering; Energiforskning; Energy research; HAT; Biomass; Biofuel; Humidification; Evaporation; Evaporative gas turbine ; Humid air turbine ; Termisk teknik; termodynamik;

    Sammanfattning : The global climate change caused by emissions of greenhouse gases from combustion processes has been recognized as a continuously growing problem and much research focuses on improving the environmental performance of gas turbines. The potential of improving gas turbine component efficiencies has become smaller each decade and therefore, thermodynamic cycles have become more interesting for power producing units. LÄS MER

  4. 18. Developing and optimizing processes for biological nitrogen removal from tannery wastewaters in Ethiopia

    Författare :Seyoum Leta; Gunnel Dalhammar; Jes Ia Cour Jenson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; biological nitrogen and supphide removal; dntififying bacteria; nitrade-reducing; sulphuroxidizing bacteria; nitrate uptake rate; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : In Ethiopia industrial effluents containing high contents of organic matter, nitrogen and heavy metals are discharged into inland surface waters with little or no pre-treatment. Significant pollution concerns related to these effluents include dissolved oxygen depletion, toxicity and eutrophication of the receiving waters. LÄS MER

  5. 19. Solar Heating with Seasonal Storage. Some Aspects of the Design and Evaluation of Systems with Water Storage

    Författare :Jan-Olof Dalenbäck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar heating; water storage; solar power; simulation;

    Sammanfattning : The report provides a basis for detailed design and evaluation of future solar heating plants with an insulated seasonal water storage. The importance of careful design and plant commissioning is pointed out and a system simulation model for future analyses of system performance is provided. A general evaluation methodology is presented. LÄS MER

  7. 20. Assessment of a partial nitritation/Anammox system for nitrogen removal

    Författare :Luiza Gut; Elzbieta Plaza; Joanna Surmacz-Gorska; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofilm; Deammonification; Nitrogen removal; Oxygen Uptake Rate OUR ; Partial nitritation Anammox system; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This thesis evaluates the performance of a deammonification system designed as a two-step tech-nology consisting of an initial partial nitritation followed by an Anammox process. Operation of a technical-scale pilot plant at the Himmerfjärden Wastewater Treatment Plant (Grödinge, Swe-den) has been assessed. LÄS MER
