Anthracite Kt Coal For Water Treatment, Color : Black

Anthracite is an excellent filter media for water clarification in drinking or industrial use, when used in combination with filtering sands. It is one of the most used filtering media. It is a good complement for the mixed filters, in company of sand or green manganese sand. Due to the special shape of its grains, it allows the suspended particles to be retained in the depth of the filtering bed. Compared to a sand filter, this filtering medium allows a higher flow, less pressure drop and a better and faster backwash.
