Anthracite for water filters
Anthracite is the highest rank of coal. It is a very hard and lustrous coal, also called “hard coal”, containing a high percentage of fixed carbon and a low percentage of volatile matter. In water treatment it is only used as a filter medium for suspended solids. Due to its hardness and characteristics, it is very difficult to activate in order to produce activated carbon.

What is anthracite?
Anthracite is an excellent filtration medium for water clarification in potable or industrial use, when used in combination with filter sands. It is a mineral coal, black in color, 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 in suspension to be retained in the depth of the filter bed. Compared to a sand filter, this media allows for higher flow performance in the filter, less pressure drop and better and faster backwashing.
It is reduced. 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 suitable and will outperform heavier media such as filter sand.
