1. 6. Shaft stability analysis of the RBR S5 : Stabilitetsanalys av axel tillhörande RBR S5

   Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Simon Lindgren; [2019]
   Nyckelord :;

   Sammanfattning : This bachelor’s thesis work completed for Spinchem intend to calculate and simulate the deflectionof a rotating shaft belonging to the rotating bed reactor S5, RBR S5. The shaft is the part thattransfers the torsion to the RBR S5 and is the part that will behave as a spring due to the rotationalvelocity. LÄS MER

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

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Alexander Berggren; [2019]
   Nyckelord :Water treatment; Mobile reactor; Autopilot; Rotating Bed Reactor;

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

   Författare :Pär Alapää; [2018]
   Nyckelord :Groundwater Remediation; Competitive Sorption; SpinChem;

   Sammanfattning : 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

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Jonathan Jonsson; [2018]
   Nyckelord :computational fluid dynamics; fluid mechanics; cfd;

   Sammanfattning : 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. LÄS MER

7. 10. Developing a measurement system of fluid velocities in rotating bed reactors

   Master-uppsats, Umeå universitet/Institutionen för fysik

   Författare :Måns Sterner Boström; [2016]
   Nyckelord :fluid measurement; hot-wire constant temperature anemometer; CTA; constant temperature anemometer;

   Sammanfattning : SpinChem AB's rotating bed reactor (RBR) is a small cylindrical centrifuge that allowsfor eective convective reactions between chemical substances. The aim of my master'sdissertation was to develop a measurement system that could estimate the uid velocity insidethe RBR. LÄS MER
