We extract water treatment gravel filtration media from Saudi Arabian purest quartz Gravel mines and manufactured through an active processing control program monitoring material by the process of washing, drying, and grading as per stringent specifications standard of ANSI/AWWA B100-09 and ASTM E11 test sieve standards.

Properties and Layers

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 an extremely effective filter media because of its ability to hold back precipitates containing impurities. Filter sand size, angularity and hardness are the important filter sand characteristics to ensure proper filtering. In slow sand filters, the gravel is normally on the bottom layer. We use them as channels for filtered water to make it to the outlet lines. Sand will often plug the holes in the outlet pipe and the gravel helps prevent that.

The primary role of the gravel in the bio-sand filter is to prevent clogging of the PVC pipe with sand. The first layer is sufficiently deep to cover the inlet to the pipe. It should be large enough to keep the openings in the filter bottom free for the flow of water out of the filter and the upper layer fine enough that the overlying filter sand will not sink into its pores.

We use sand and gravel for road construction, mixing with asphalt. Additionally, we use it as construction fill and in the production of construction materials like concrete blocks, bricks, and pipes. We also them to make roofing shingles. We use them on icy roads in the winter, for railroad ballast, and water filtration. The quarry is often where we excavate our gravel and other aggregates and where we crush rocks such as sandstone and basalt down to size.
