Description 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 and is used 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 and 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. Sand and gravel are used for road construction, for mixing with asphalt, as construction fill, and in the production of construction materials like concrete blocks, bricks, and pipes. It is also used to make roofing shingles, used on icy roads in the winter, for railroad ballast, and water filtration. The quarry is often where our gravel and other aggregates are excavated and where rocks such as sandstone and basalt are crushed down to size.
