What is Anthracite Filter Media?

Anthracite is lighter and coarser than sand, so it sits on top after backwashing. Solids are captured through the depth of the bed rather than only at the surface, which extends the time between backwashes.

Where anthracite is used

  • Multigrade filters before RO
  • Raw water and tertiary effluent filtration

How to use anthracite

  1. Layer anthracite above sand.
  2. Backwash to restratify the bed.
  3. Top up any losses from backwashing.

Frequently asked questions

Why add anthracite to a sand filter?
