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.
