Anthracite Filter Media
Anthracite filter is a hard, compact variety of mineral coal that has a high luster.
It has the highest carbon count and contains the fewest impurities of all coals, despite its lower calorific content.
Anthracite is the most metamorphosed type of coal (but still represents low-grade metamorphism), in which the carbon content is between 92% and 98%.
Anthracite media is hydraulically classified to reduce foreign mineral matter and to lower ash content.
The water filtration media is then screened and washed to ensure suitability for water filtration purpose .
Anthracite characteristically produces reliable improvements in turbidity removal, mostly due to better solids holding capacity. Additionally, low uniformity coefficient media improves flow rates.
Of all the carbon materials, this black and rather shiny mineral is the hardest of them all. Long used in water filtration applications, the anthracite used for water filtration is usually specially selected from deeper mines, where, due to higher pressures, the carbon content is typically even greater.
