Performance assessment of a bench scale hybrid filter in the collection of nanoparticles

Hybrid filtration of sinter dust: An alternative for air pollution control in steel industries

“…The pvalues in these cases were higher than 0.05, indicating that the three values of each block were statistically equal to each other. This result differs from those obtained by Feng et al (2016) and De Castro et al (2021), which showed that the increase in the electric voltage applied to the ESP increased the collection efficiency of the FF of the hybrid system. There are three reasons for this apparent divergence.…”

“…Secondly, the diameter ranges of the evaluated particles were very different. Feng et al (2016) evaluated the collection efficiency of particles with diameters in the range of 0.5-2.5 μm, and De Castro et al (2021), of particles in the range of 0.01-0.3 μm. In both cases, there was a considerable portion of particles with diameters in the range in which the mechanical collection mechanisms -Brownian diffusion, interception and inertialare ineffective.…”

Use of hybrid filters to optimize the process of the filtration in cement particles

“…Consequently, in addition to the mechanical mechanisms of particle collection by the fibers of the filter medium, there was also the action of the electrostatic mechanism. If the fibers of the filter media did not contain electrical charges, the electrostatic attraction occurred through the action of the image force, generated by the polarization of the fibers due to the presence of electrical charges in the particles [ 18 , 27 ].…”
