It is interesting to discuss the debate generated to explain the presence of atypical anthracite in some regions, identified as lacking groupings of traceability; between two major currents of thought evolutionists and creationists these past defending the idea of a natural disaster of epic proportions, (deluge) determine the transport of trees of a region in which were not originating in another (where encountered them) as well as the presence of marine fossils embedded this mineral, in regions where the adjacent material does not have the same origin. The degree of a mineral coal measures according to the range (purity) is interpreted that those with greater range have concentrations of coal larger per unit volume, by determining first, as already stated to the anthracite, which among other things has no volatile which requires a special effort to cause ignition and generates little smokeas well as one called Blue small, the low volatile bituminous relocated to second place in this classification after the anthracite with a heat capacity close to 30 MJ / Kg, that is why the coal and the anthracite are very attractive in metallurgical applications used in filters multi-Media. due to its density relatively average, will remain on heavier mediums such as sand or Garnet that provides an excellent layer of pre-filtration. Anthracite media are a qualified crushed coal selected specifically for the treatment of water is one of the most commonly used media, is basically crushed and sifted with granule activated carbon ranging from 0. 5 m to 3 m. It is a good complement for filters of multiple media, in the company of manganese green sand or sand.

Anthracite filtering materials are selected specifically for deep mines which have the highest percentage of carbon. Drinking water filtration sand materials are hydraulically classified to reduce the presence of foreign minerals and ash content. Water filtration media are then filtered and washed to ensure its suitability for the purposes of filtering water. The anthracite is characterized by producing reliable improvements in the removal of turbidity, mainly thanks to its greater ability to retain solids. In addition, the media with low uniformity coefficients enhance flow rates. Andec S. a.
