Hydro Anthracite

Water Filtration Application

Hydro-Anthracite can be used alone for water filtration or with various sizes of sand in dual-media filters. Its unique shape and density allow it to filter more efficiently, making it the perfect media for the filtration of drinking water, processed water, pool water, waste water, industrial water, and municipal water.

  • Low dry bulk density and high strength necessary for nano-filtration (suspended solids with SG less than 1)
  • Irregular granule shapes don’t pack down as tightly as filter sand
  • Filters larger particles and coagulated suspended matter more efficiently
  • Will not perform adsorption
  • Longer filter runs than traditional filter sands
  • Less head loss and backwashing than traditional filter sands
  • Angular sediment penetrates deeper into the bed
  • Large volumes of suspended matter and particles can be removed with one multimedia filter (quartz sand and Hydro-Anthracite)
  • Hydraulically classifies at 850kg/m3 and remains above heavier media, providing a pre-filtration layer
  • Lower uniformity coefficient results in a highly uniform bed


  • Carbon content between 79% and 81%
  • 2.75-3 hardness on Mohs scale (higher than other bituminous coals)
  • 1.3-1.4 relative density (higher than other bituminous coals)

General Information

Anthracite was created by the fossilization of dense green vegetation in the Carboniferous Age. It is a very hard variety of coal with the fewest impurities, no fibrous notches, and the highest carbon content available.

The first water filtration systems were made in the 1700s using wool, sponge and anthracite. African Pegmatite’s milled Hydro Anthracite is a South African tailor-made product formulated specifically for today’s demanding water filtration requirements.
