A mineral analysis of some common sands and …
The detailed mineralogic analyses show: (1) The percentage of silica in the heavy mineral portion is fairly regularly inversely proportional to the percentage of heavy minerals in the sands. (2) The abundance of grains of the different minerals in the various grain sizes varies regularly with some minerals and irregularly with others. Some minerals, e.g., zircon, are markedly confined to ...

Sand / Media Specifications
Media with small grain size slow the water movement and increase the chance of clogging. The effective size (D 10) and uniformity coefficient (Uc) are the principal characteristics of granular media treatment systems. 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 ...

calculating the hydraulic conductivity of uniform sands using effective grain size. The term "effective grain", used for grain diameters in both formulae, could lead to confusion (Mavis and Wilsey, 1936). However, Hazen's formula uses D 10 (soil particle diameter where 10% of all soil particles are ﬁner (smaller) by weight), and Slichter proposes using the mean diameter. This confusion ...
