FILTER MEDIA - FILTER SAND & GRAVEL

This type of sand and gravel are graded specifically for water filtration plants. Filter sand can be used in municipal, industrial or residential applications.

The spherical shape of uncrushed gravel promotes good flow and even distribution. Low soluble impurities limit undesirable mineral leaching into the process stream.
