Anthracite

Anthracite filter media for dual-media and multi-grade filters.

What is it?

Low-ash anthracite coal media used as the upper layer in dual-media filters. Its lower density and angular shape let it sit above sand after backwash, providing coarse-to-fine depth filtration, longer runs and lower pressure drop.

FAQ

Anthracite — FAQ

Why use anthracite over sand alone?

A properly designed anthracite-over-sand bed filters coarse-to-fine, which increases solids-holding capacity, extends filter runs and reduces backwash frequency compared with sand alone.
