Coal can be produced in the form of powder, granules or cylindrical pellets.
The powder is only applied in the purification of liquids; the carbon is dosed into a tank with agitation and then separated from the liquid by means of a filter suitable for retaining small particles (such as a filter press).
In the case of granular coal, it is produced in different particle size ranges, which are specified based on particle size or mesh number. A 4 mesh, for example, is one that has four holes in each linear inch. They are applied both in the purification of liquids and gases.
Pellets are used in gas treatment, since their cylindrical shape produces a lower pressure drop.
In the case that a granular coal or pellet is desired, if the raw material is not hard enough, it can be reagglomerated with a binding agent that imparts hardness to prevent it from breaking when the fluid passes through.
