Water Treatment Gravel Filter Media is extracted from the purest mines in Saudi Arabia and is manufactured to sieving standards that monitor material manufacturing through washing, drying, and grading processes according to strict specification standards tested to ANSI/AWWA B100-09 and ASTM E11.
Gravel is used in Water Filtration with water treatment Filtration products Silica Sand, Anthracite, Activated Carbon, Birm, Pumice and Garnet in portable water treatment, surface water treatment, swimming pool water treatment, R.O. reverse Osmosis treatment plant and wastewater treatment also in conventional water treatment filters. Filter Gravel is a very effective filter medium because it stops sediment from containing impurities. Sand size, angularity, and hardness are important sand characteristics to ensure proper filtration. The quarry excavates our aggregates and crushes the rocks such as sandstone and basalt to size.
Gravel is divided into particle size groups, ranging from granules to boulder-sized chunks. Gravel is divided into granular gravel (2–4 mm or 0.079–0.157 in) and pebble gravel (4–64 mm or 0.2–2.5 in) on the Udden-Wentworth scale. Gravels are classified as fine, medium, or coarse according to ISO 14688, with sizes ranging from 2–6.3 mm to 20–63 mm. Gravel normally weighs around 1,800 kg per cubic meter (or a cubic yard weighs about 3,000 lb).
