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.

Roughness Control

Austenitic stainless steel filters are mostly used when there is an aggressive environment condition, especially when good corrosion and mechanical resistance at relatively high temperature are required. These filters are usually obtained from non-spherical, mostly atomized powders by cold pressing and sintering. In order to achieve an adequate performance concerning permeability, powders with a narrow range of particle size should be used. However, besides particle size distribution, apparent density of the selected powder, which can be adjusted by the particle size, shape and distribution, affects the performance of the final product. Particle size distribution, particle shape and particle surface roughness control apparent density. This work presents some results on the evaluation of such effect.
