This study deals with the experimental evaluation of some relevant ash samples collected from the flue gas filters of a hazardous waste incinerator plant. The experimental analysis focuses on size, distribution and dielectric properties of the samples. The reported results reveal the presence of nanoparticles in the samples and the possibility to use dielectrophoresis for their handling. The study exploits also numerical simulations in order to investigate the behavior of nanoparticles with size range from 50 to 150 nm, which is fructified as a micro channel – working unit used as a particulate trap. Based on the experimental data and a proposed mathematical model, the concentration profile of nanoparticles suspension inside a micro fluidic separation device is calculated and the performance of the device is analyzed in terms of three new specific quantities of separation process, called Recovery, Purity and Separation Efficiency.
