Triboelectric Charging

Four types of particulates filtration mechanisms. The representative PM filtration mechanisms: impaction, interception, diffusion, electrostatic attraction.
Intensifying air pollution has engendered growing public health concerns due to its broad and adverse effects on humanity. As a result, the development of air filtration technologies has received increased attention as a practical and promising solution. Till now, many efforts have sought to advance air filtration technologies to overcome the trade-off relationship between filtration efficiency and pressure drop.
