Sand / Media Specifications

The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging. KEYWORDS: sand/ media specifications, filter media, media grain size

Hydraulic Properties :. Aquifer Testing 101

Hydraulic conductivity of selected consolidated and unconsolidated geologic materials (from Heath 1983). Grain Size Relationships. A number of empirical formulas, some dating back over a century, have been proposed which attempt to relate the hydraulic conductivity of an unconsolidated geologic material (granular sediment or soil) to its grain size distribution obtained from sieve analysis.

Sedimentary particles shape: sphericity and …

The shape of a sedimentary particle, or grain (what we called gravel, sand, silt, and clay) is essentially its geometric form. The geometric form of a particle depends on two different concepts: the relative length of the particle intercepts along the three perpendicular axes A, B, and C, corresponding to three orthogonal axes X, Y, and Z (its sphericity )
