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.)
- 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.
- 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.
- 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.
