For a given sand number, crushed silica retains smaller particles than does sand. The recommended design filter flow rate depends on the amount of suspended material in the water. For dirty water (100 ppm or more of suspended material), an acceptable filter flow rate is about 15 gallons per minute per square foot of filter area.
The recommended filter media are crushed basalt, crushed silica, quartz sand, AFM/Pep Active, and other catalytic media. The varying sizes of the media cause the water to flow through a maze of passages on its way through the media bed, from the inlet to the outlet of the filter.

Crushed glass filtration media generally removes finer particles from water than silica sand of an equivalent grade, and is comparable to properly configured ZEOlite. Weak negative surface charge holds fine particles and positively charged iron and manganese ions that are easily released upon backwashing for
Silica sand was first used as a water filtering media in 1804, by John Gibb. The use of this media took over two decades to polish to perfection. The United Kingdom currently uses four ranks of silica sand for its water filtration processes. Silica sands that are appropriate for filtration have a sub-angular or round shape.
Crushed silica filters better than sand because the angular particles of the crushed material fit together more closely. Sand media filters are cleaned by back-flushing. These filters must be installed in banks of two units or more as during back-flushing water flow is reversed through one filter at a
A media filter consists of a pressurised tank containing the filtration medium, which is generally a crushed basalt or a graded silica sand. Media filtration, like disc filtration, is multi-layered and offers depth filtration.
Glenellas fine sand is highly suitable for use in the manufacturing of concrete blocks and pavers. The grading is also supplied in bulk for use in landscaping, sports surfaces, block manufacturing, filtration and golf course bunkers. Course sand is used in many different applications due to its large particle size and silica content.
In order for the filter to be effective, each grain of sand must be roughly the same size, generally 0.4 to 0.6 millimeters.
