  1. 6. Conflict, narratives, and forest fires in eastern Turkey : a quantitative perspective with remote sensing and GIS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aiman Shahpurwala; [2019]
    Keywords : geography; burned area; Turkey; warfare ecology; spatial analysis; GEM; Earth and Environmental Sciences;

    Abstract : Within Turkey, claims of an increasing number of forest fires ignited by the Turkish military to ‘strategically degrade the environment’ broke out after the Turkish-Kurdish peace process ended in 2015. These claims are built on little evidence, and fire occurrences are not well documented. READ MORE

  3. 7. Development of a Mobile Reactor for Large Scale Water Treatment

    University essay from Umeå universitet/Institutionen för fysik

    Author : Alexander Berggren; [2019]
    Keywords : Water treatment; Mobile reactor; Autopilot; Rotating Bed Reactor;

    Abstract : Water pollution is one of many environmental problems that currently exists and inadequate treatment of industrial wastewater is contributing to further pollution. SpinChem AB's Rotating Bed Reactor (RBR) technology offers the possibility of water treatment by carrying out reactions between a solution and a solid phase. READ MORE

  4. 8. Remediation of Contaminated Groundwater Using a SpinChem® Rotating Bed Reactor : Competitive Sorption of Metal(loid)s in Complex Solutions under Varying Geochemical Conditions

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Pär Alapää; [2018]
    Keywords : Groundwater Remediation; Competitive Sorption; SpinChem;

    Abstract : The potential of utilizing a new form of chemical processing technology called SpinChem® Rotating Bed Reactor (RBR), in combination with different reactive materials, for the purpose of remediating multi-contaminated aquifers under changing environmental conditions, was investigated using laboratory studies and geochemical models. Four different reactive materials, or combinations thereof, were tested: heat-treated peat powder combined with zero-valent iron (ZVI); IronPeat, which consists of peat powder coated with a ferriferous hydrosol (FFH); and a powdered steel waste product.

  5. 9. Modelling adsorption rate in a rotating bed reactor

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonathan Jonsson; [2018]
    Keywords : computational fluid dynamics; fluid mechanics; cfd;

    Abstract : SpinChem AB designs rotating bed reactors (RBR:s) that are used to conduct reactions between solid and liquid phase. In this work a model have been developed that predicts the performance of the S2 RBR. Coupled with simulations the model could be used to improve current and future RBR designs. READ MORE

  6. 10. Development of a CFD Model for a Rotating Bed Reactor in Large Volumes

    University essay from Umeå universitet/Institutionen för fysik

    Author : Karl Lundberg; [2017]
    Keywords : computational fluid dynamics; fluid mechanics; cfd;

    Abstract : Den roterande bäddreaktornSpinChem® RBR S2 kan fyllas med solida partiklar och sänkas ned och roteras ien vätska. Detta gör att kemiska reaktioner mellan vätskan och partiklarna iRBR:en kan äga rum.Flödet från en RBR S2 i en 76 dm3 stor vattentank undersöktes med hjälp avsimuleringar i ANSYS Fluent 18.0.
