Four grades of silica sand are used for water filtration in the UK today, these are 6/14, 8/16, 14/25 and 16/30. The silica sand is usually laid on top of a supporting layer of gravel within the filter vessel. The incoming water enters the filter and migrates through the silica sand, successfully removing any solids or debris from the water.
Highrate sand filters use a special filter sand, normally .45 to .55 mm (also known as pool grade #20 silica sand), because it has sharp edges that separate particles, allowing filtration to take place. They operate on the basis of "depth" filtration where dirt is driven through the sand bed and trapped in the spaces between the sand ...
