Return to What is Industrial Sand?

Filtration and Water Production

Industrial sand is used in the filtration of drinking water, the processing of wastewater and the production of water from wells.  Uniform grain shapes and grain size distributions produce efficient filtration bed operation in removal of contaminants in both potable water and wastewater.  Chemically inert, silica will not degrade or react when it comes in contact with acids, contaminants, volatile organics or solvents.  Silica gravel is used as packing material in deep-water wells to increase yield from the aquifer by expanding the permeable zone around the well screen and preventing the infiltration of fine particles from the formation.
