Sand Filter an overview ScienceDirect Topics

The homogeneous sand filter has a 0.9–1 m deep bed and typically of 0.85–1.7 mm of sand (effective size 0.9 mm) placed on a 50 mm layer of 4–8 mm or 75 mm of 6.7–13.2 mm gravel. Homogeneous sand of effective size up to 1.3 mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.

What is a Sand Filter? (with pictures) wiseGEEK

Over time, the sand loses its rough edges and is less effective. Thus, the system has to spend more time running in order to filter as well as it did when the sand was new. This can shorten the life of the sand filter.
