The paper examines the importance of size distribution of the influent suspension on the performance of deep bed filters and its significance with regard to modelling. Experiments were carried out under a variety of conditions using suspensions which were identical in every respect apart from their size distribution. The results indicate that the presence of coarse particles does increase the removal of fine particles. Deposition of fine particles leads to a greater headloss than deposition of large particles. Changes in size distribution with time and depth play an important role in determining the behaviour of a filter, and models of both removal and headloss development must take account of this.

Size Distribution Of Particles

The particle size distribution and the reflectance properties of silvered glass mirrors exposed in an outdoor environment have been measured to determine the separate effects of natural soiling and natural cleaning (wind and rain). The wavelength dependent diffuse reflectance was correlated with the particle size distribution function for mirrors exposed to increasing periods of outdoor exposure. These measurements have indicated the significant role of small particles (radii ≲ 5 μm) in the soiling of exposed mirrors and in the subsequent reflectance loss over the solar spectrum.

Abstract The particle size distribution of the rubber globules in Hevea latex has been studied by means of electron microscopy. Most of the particles, even in concentrated latex, are less than 0.2 micron in diameter and are, consequently, not visible in the light microscope. These small particles have considerable influence on the specific interface, but they contain only a few per cent of the rubber present.
