    Sammanfattning : The legal requirements for wastewater discharge into environment, especially to zones exposed to eutrophication, lately became stricter. Nowadays wastewater treatment plants have to manage with the new rules and assure better biogenic elements’ removal, in comparison with the past. LÄS MER

  4. 23. Diagnostic Methods for Composite Insulators with Biological Growth

    Författare :Andreas Dernfalk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; algae; composite insulators; Hough transform; biological contamination; outdoor insulation; digital image analysis; laser-induced fluorescence LIF ; fungi; diagnostic methods;

    Sammanfattning : Composite insulators have a number of advantages compared to conventional insulators, but the fact that they are more prone to aging is a major drawback. For instance, biological growths, like algae and fungi, have been found to colonize composite insulators, and possibly effecting the insulation performance. LÄS MER

  5. 24. Residual Stresses and Fatigue of Shot Peened Cast Iron

    Författare :Mattias Lundberg; Lin Peng Ru; Sten Johansson; Taina Vuoristo; Daniel Bäckström; Maqsood Ahmad; Jens Bergström; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The complex geometry of cylinder head in heavy-duty diesel engine makes grey cast iron or compact graphite iron a perfect material choice due to its castability, thermal conductivity and damping capacity. To increase the efficiency of the engine, the fatigue property of the material needs to be improved. LÄS MER
