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.

CIVL 1101 - Introduction to Water Filtration
The use of a single-medium coarse-sand filter is practiced in Europe. For example, sand with a size range of 0.9-1.5 mm and about 1.0 m depth has been used in surface-water treatment plants. These filters are scoured with concurrent air and water at nonfluidizing velocity followed by a brief wash at high velocity with water alone.

Slow sand filters are similar to the rapid granular filters, except that water flows through the filter at a much slower rate, 0.05–0.15 gal min −1 per square foot of surface area, and pretreatment (coagulation, flocculation, and sedimentation) is often omitted. Removal occurs primarily in the upper portion of the sand, by straining ...
Filtration - MRWA
Filter Sand . The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.

Slow Sand Filtration for Water Treatment
Slow sand filtration relies on both physical and biological activity in controlling plant pathogens. In a slow sand filter, the filter bed is constructed of a medium with high surface area which can be colonized by suppressive micro-organisms. This fine media also presents a physical barrier to the passage of spores of plant pathogens.
