  1. 1. Upflow anaerobic sludge blanket reactor modelling

    Detta är en avhandling från Stockholm : US-AB

    Författare :Raul Rodriguez; KTH.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; wastewater; anaerobic treatment; modelling; UASB reactor.; MEDICINE Chemistry; MEDICIN Kemi;

    Sammanfattning : Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The two principal advantages of anaerobic over aerobic treatment are the production of biogas, which can be used as fuel, and the lower rate of biomass production, which results in lower maintenance costs for the plant.

  2. 2. Study of precipitation in martensitic Fe-C-Cr alloys during tempering Experiments and modelling

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

    Författare :Ziyong Hou; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe-C-Cr alloy; Microstructure; Precipitates; Tempering of martensite; Electron microscopy; Modelling.; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Understanding the precipitation reaction is very important since precipitation hardening is one of the most effective strengthening mechanisms in metallic alloys. In martensitic steels, a tempering heat treatment is often performed. LÄS MER

  3. 3. Delamination in APS applied thermal barrier coatings : life modelling

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Magnus Jinnestrand; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Thermal barrier coatings, TBCs, are used in gas turbines as a thermal shield resulting in lower temperature in coated components. The decrease of temperature allows higher gas temperatures in the turbine, which increase the efficiency. LÄS MER

  4. 4. Closing the Loop by Combining UASB Reactor and Reactive Bed Filetr Technology for wastewater Treatment Modelling and Practical Approaches

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

    Författare :Raúl Rodríguez-Gómez; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bench-scale experiment; Modelling; Polonite; Sorbulite; UASB; Wastewater; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : A laboratory-scale upflow anaerobic sludge blanket (UASB) reactor followed by a packed bed reactor (PBR) filled with Sorbulite® in the lower part and Polonite® in the upper part was used to treat household wastewater in a 50-week experiment. A model was developed to describe the performance of the UASB reactor, including mass transfer through the film around anaerobic granules, intra-particle diffusion and bioconversion of the substrate.
