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, wastewater, 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
