Basis of Soil Classification

Sand, which is influenced more by particle size, is subdivided into four categories – fine, medium, coarse, and very coarse. A new soil category, Mo, has been introduced that has a particle size of 0.02-0.1 mm and is finer than sand and coarser than silt. Silt and

Particle Size Distribution

This section discusses particle distribution. The finer sizes are called fine earth (smaller than 2 mm diameter) as distinct from rock fragments (pebbles, cobbles, stones, and boulders). Particle-size distribution of fine earth or less than 2 mm is determined in the field mainly by feel. The content of rock fragments is determined by estimating the proportion of the soil volume that they occupy.

Sand Filter

Sand filters use either graded sand (fine to coarse or heterogeneous) or coarse monograde sand (uniform size or homogeneous). No single media specification (size and depth) can be applied universally for all waters; the choice depends on the water quality and upstream processes, filtered water quality objectives, cleaning method, filtration rate and length of filter runs.
