Anthracite Filter Media Overview
The anthracite coal used for filtration is primarily mined in Northeast Pennsylvania. Anthracite is a harder and cleaner than bituminous coal making it an ideal component in filtration configurations. (Bituminous coal is commonly used for the manufacture of activated carbon.)

Features
- Anthracite is seldom used as a singular filtration media. Combined with sand it is in-depth filtration; combined with garnet, sand and gravel it is a multi-media filter.
- Anthracite has no chemical properties which enable it to remove or react with contaminants.
- Anthracite has no temperature limits.
- Use anthracite filter media certified to meet AWWA Standard B-100 and NSF/ANSI Standard 61.
Applications
- Anthracite can be used in place of filter sand in applications sensitive to silica.
- An “anthracite cap” (anthracite which is loaded on top of the greensand) is often used in greensand applications to capture iron and manganese precipitates. Form more information about the anthracite cap listen to this podcast – Is Greensand Green
- Graded anthracite is often used as a sub-fill for industrial softeners and filters. It is not recommended for granular activated carbon (GAC) filters if carbon reactivation is planned.
- Anthracite is commonly used in municipal filtration.
