Abstract

On filtering particles of silica or iron oxide from water with filter paper, or a cartridge built of rayon fibers, the filtration efficiency, E, of 1 to 10 μm particles changed from 0.4 to 0.999 with changes in temperature, viscosity, and liquid flow rate. Variations in temperature and in viscosity changed the Brownian diffusivity, D, of the particles. Correlations are shown between D and log R, where R = 1/(1 - E). The results indicate the importance of specifying these variables in any referenced filtration test.

Keywords:
liquid filtration, Brownian diffusivity, liquid flow rate
