ANTHRACITE
ANTHRACITE is filter media for water purification
made of broken and sifted natural anthracite
coal. Abrasive-resistant grains are characterized
by their sharp edged structure and a splintery
shape of grain. It is produced from highest quality
anthracite available to ensure the physical
characteristics of hardness, durability and
performance. ANTHRACITE is used mainly as
an upper layer of materials in dual media filters
or multi media filters
F eatures
• combine with fine grain
materials as a lower material
layer to cause improved and
stable filtrate quality
• extension of filter runs
• reduction of backwashing
water consumption
