Ding Long Minerals products a full range of grades of anthracite filter media. These are produced from the anthracite mined in China, and are sold throughout the world.


Anthracite Filter is often used to produce a multi-media filter.This has several advantages over a single media filter.


* Increased filtration rates

* Longer filter run times

* Reduced backwash water consumption The bed of anthracite placed on top of the sand layer provides the filter with.

* Larger grain particles on the surface of the filter which delays the pressure drop across the filter.

* A larger reservoir in which the floc may be held before backwashing.

* A prefilter for sand filter below.


The grade of anthracite filter media is chosen so that it has a similar backwash expansion as the sand below it. This is important to prevent losses of anthracite during backwashing.
