What is anthracite?

Anthracite is an excellent filter medium for clarifying water in potable or industrial use, when used in combination with filter sands. It is a mineral carbon, black, shiny, with great hardness, it has a higher carbon content, up to 95%.

Due to the special shape of its grains, it allows the material that is in suspension to be retained in the depth of the filter bed. Compared to a sand filter, this filter media allows for higher flow filter performance, less pressure drop, and better and faster backwash.

The backwash flow is also low. Due to its unique density, anthracite can be used in multimedia or deep bed filters. At a density of 50 lbs / ft, it is hydraulically adequate and will outperform heavier media such as filter sand.
