Anthracite Filter Media

Anthracite is an organic metamorphic rock formed from ancient vegetation and consolidated between other rock strata to form coal seams. Anthracite filter media is produced by crushing, drying, sieving and packing Anthracite rocks.

Anthracite is washed, dried, and sieved to standard grain sizes that meet or exceed international standards such as AWWA B100 and / or EN12909.

Anthracite is used in mono media filters or as an upper layer of dual / multimedia filters, its relative low density ensures good layers separation and higher solid retention within upper layers of filter media.

  • We offer both low density and regular density Anthracite filter media. 
  • Acid Solubility is tested in 10% HCl solution for 24 hours. 
  • Attrition loss is calculated on basis of 100 hours of backwash

  • The lower the density is, the higher the bed expansion, and the lower the UC value the greater the part of the bed that expands, thus ensures best cleaning. 

  • ENSYAB supply superior quality, low-density (~750 kg/m3), low UC (<1.3) Anthracite filter media beside regular density anthracite.
