ANTHRACITE

Surface water often appears translucent and is turbid in nature. To overcome this turbidity and allied problems like iron content, suspended solids, etc, anthracite serves to be a good option as a filter media. Its high void capacity results in effective and bulk turbidity removal. Low specific gravity contributes to its light weight. The rich angularity and complicated form accelerates the flocculation in voids which contributes in filtration. Moreover, the suspended solids are retained in its intergranular spaces. The long life span is the result of its low uniformity coefficient.


ACURO's high quality anthracite ensures durability, high performance and remedial solution to the water hardness. Its high chemical resistance makes it non-dissoluble in an acidic and alkaline medium. It has a long life and wide temperature ranges. The silica free constituent results in ultra pure water.


FEATURES :

  • Wide temperature ranges and long life span.
  • No chemicals required for maintenance.
  • High chemical resistance.
  • Durable and lower backwash rate.
  • NO silica content.
