Research of biosorbents with natural ferrimagnetic properties for water purification
The aim of the project is to substantiate and develop theoretical and experimental scientific principles of technology of natural and artificial magnetic labeling of microorganisms and fungi from BMN for water purification. As a result of the research, potential producers of BMN were identified among microorganisms from BMN (bacteria, microalgae) and fungi used for water purification. Systematized microorganisms from BMN (bacteria, microalgae) and fungi, in the presence or absence of crystal structure and localization of BMN formations. A method of processing biosorbents in external electric and magnetic fields with natural ferrimagnetic properties for wastewater, natural and drinking water treatment has been developed. Drawings of a laboratory installation for the manufacture of biosorbents with weak natural ferrimagnetic properties have been developed. Experimental data on the efficiency of extraction of spent biosorbent with natural ferrimagnetic properties using VGMS with VGFN were obtained. The model of magnetodipole interaction that occurs between BMN of microorganisms (bacteria, microalgae) and fungi used for water purification and artificial magnetic nanoparticles during their magnetocomposition is calculated; model of magnetohydrodynamic effects, calculation of magnetostatic scattering fields by ferromagnetic samples; model of the process of capture of magnetically controlled biosorbent by single-level and multilevel (dendritic) ferromagnetic nozzle in magnetic field. Experimental data on the magnetic properties of microorganisms from BMN (bacteria, microalgae), fungi and artificially magnetized microorganisms from BMN (bacteria, microalgae) and fungi were obtained, their sorption abilities were determined and the efficiency parameters of homogeneous magnetism were established.
