  1. 16. A small scale wastewater treatment system adapted to nutrient recovery in cold climate : performance and possible sorbents

    Författare :Lea Rastas Amofah; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Waterbodies are impaired by, among other things, discharge from onsite small- scale wastewater (WW) treatment systems. Hence, these systems need to be updated to improve the effluent quality and the reuse of nutrients within society. LÄS MER

  3. 17. Factors affecting MFI membrane quality

    Författare :Charlotte Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Zeolites are crystalline aluminosilicates with molecular sieving properties and are widely used in industrial applications such as catalysis, sorption and ion-exchange. Zeolite membranes are highly interesting due to their capability to continuously separate molecules under severe conditions. LÄS MER

  4. 18. Succinic acid production using metabolically engineered Escherichia coli

    Författare :Christian Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : The prospects of peak oil, climate change and the dependency of fossil carbon have urged research and development of production methods for the manufacture of fuels and chemicals from renewable resources (biomass). To date, the primary emphasis has been placed on the replacement of oil for transportation fuels. LÄS MER

  5. 19. Product innovation processes : conceptual and methodological considerations

    Författare :Sven Andersson; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Redovisning och styrning; Accounting and Control;

    Sammanfattning : This thesis addresses the social dimension of individuals engaging in the product innovation process in order to develop and choose techniques for knowledge creation about the social evolvement of a product innovation. The social dimensions of product innovation processes are particular interesting, since many firms today organize their processes by combining individuals from different functions and knowledge areas.

  7. 20. Analysis of 3D surface data for on-line determination of the size distribution of iron ore pellet piles on conveyor belt

    Författare :Tobias Andersson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Size measurement of iron ore pellets in industry is usually performed by manual sampling and sieving techniques. The manual sampling is performed infrequently and is inconsistent, invasive and time-consuming. Iron ore pellet's sizes are critical to the efficiency of the blast furnace process in the production of steel. LÄS MER
