Abstract

This paper presents the mechanisms of nanoparticles retention on nonwoven filter media during depth aerosol filtration and the influence of parameters such as particle size, linear velocity and gas temperature, fibre diameter and packing density and surface charge of particles and fibres on retention efficiency of particles according to the classic filtration theory. Based on a review of literature sources, a comparison of filtration efficiency results obtained on the basis of classic filtration theory and experimental results is presented.
