Title : Neutralization reaction induced by different types of magnetic field
The study investigated the possibility of conducting mixing process in a custom mixing system equipped with a magnetic field generator. Research installation used in this work was created to the needs of research project no. UMO- 2018/31/B/ST8/03170 realised within OPUS 16 competition organised by the National Science Centre (NCN) in Poland.
The aim of presented work was to apply magnetic fields (rotating magnetic field, static magnetic field, pulsating magnetic field and oscillating magnetic field) for intensification of neutralization process. The second step was to use the obtained results to the analysis of magnetic fields. Finally, the results were compilated in the form of mathematical relation and compared with each other.
The process of mixing liquids is usually carried out with the use of various types of mixers equipped with a mechanical agitator. In literature one can find various types of mixers, agitators and alternative ways to proceed mixing process, for example using magnetic fields. In presented work it was demonstrated, that some types of magnetic fields may be used to intensify neutralization process by the force of mixing.
The results showed the differences in hydrodynamic of the liquid exposed to the influence of various types of magnetic fields, what means that one can use some of this types in specific mixing setups. Additionally, it is possible to use ferromagnetic (Fe2O3) as a strengthening factor, thanks to which much better mixing properties may be obtained. This specific mixing system may be used in processes of mixing in biotechnology, where microorganisms are exposed to stress connected with specific process of mixing.
