Although anthricite is coal and predominantly carbon, it is not activate carbon. Because it has not gone through the activation process, it is not porous and it will not perform adsorption. It does not filter bacterial size particles, like diatomaceous earth.
Anthracite is commonly used in industrial and municipal water filters. It is not as common in the swimming pool industry where silica sand is the predominant media.
If you are looking for a replacement for anthracite sand, the closest material I can think of are the light-weight sands that are processed from volcanic pumas. One of these products is a product sold under the trade name "Filter-AG" sand. Agiean sand and Zeolite sand are others. However, these products are a good deal more expensive than anthracite.

The anthracite is not necessarily needed; but, it can help.

You can count on one hand the instances of anthracite coal usage as a topping for sand filtration in the swimming pool market......it's simply not needed given the routinely low level solids requiring removal from pool water, easily handled and disposed of by periodic backwashing of the filter to waste.
