Nano Ferromagnetic Fluid Filter of Micro Particles on The Traffic Road

Abstract
Particle matter (PM) of different dimensions and shapes are present in large quantities on a daily basis, especially above the city's roads. The sources of these particles are mainly motor vehicles, in particular diesel vehicles, tire wear, wear of cylinder motors and brake discs. Particle matter larger than 10 µm can not pass through the mucous membrane of the respiratory organs, while particle matter penetrates less 0.5 µm deeply into the bloodstream. These particles are porous structures and carcinogenic substances can accumulate within them. In this way, particles below 0.5 µm become indirect causes of carcinogenic diseases. The nano ferromagnetic fluid filter (NFFF) is an innovative solution that can be installed on every motor vehicle. This filter uses magnetic nanoparticles to separate the solid particles below 0.5 µm . This paper analyzes the efficiency of the NFFF system of the motor vehicles located above city roads.Nano ferromagnetic particles are not consumed during the separation of solid particles from the air, but are continuously circulated through this filter system. The dispersion of the nano ferromagnetic particles in a separate magnetic chamber is carried out by volume capture of solid microparticles and extraction from the air. In this way, motor vehicles with the installed NFFF system separate the existing microparticles above the city's roads before they are dispersed in the environment. Using the described NFFF system, the function of motor vehicles has been extended to improve the health of people in urban environments.
