Chemical Effects in Particulate Filtration. 2. Observations on Particle Loss.

Abstract

As part of a program of filter testing, monodisperse aerosols ranging in size from 0.01 to 0.30 micrometers were prepared from seventeen materials. With particles of a few hundredths of a micron diameter, losses in the test system lines were frequently much larger than expected, and varied greatly from one material to another. There was no obvious correlation between the magnitude of the effect and the chemical nature of the aerosol. These abnormal losses were greatly reduced or eliminated when the aerosol was passed through a neutralizer, which removed most of the particle charge in this size range. A more systematic study of the phenomenon should be made, with a system designed expressly for the purpose.
