Anthracite is a hard, compact assortment of mineral coal. It has a high gloss finish. It also has the most elevated carbon content, the least pollutions, and the most astounding calorific substance of a wide range of coal, which likewise incorporate bituminous coal and lignite.

Anthracite coal is utilized broadly in water filtration and in water treatment as a result of its incredible filtration properties. Anthracite coal is a top quality coal that comprises of hard, tough coal particles that come in different sizes. Anthracite is utilized alongside silica sand (double media framework) or with silica sand and channel shake (blended media framework) or by itself (mono media framework).

2. Filter Garnet

Garnet sand is utilized as a bolster layer in a multi-media filtration framework. Garnet occurs naturally and is a gem mineral with uniform physical, synthetic, hardness, friability and smaller scale structure qualities, which give the basic properties to water and mechanical concoction filtration forms. Applications for garnet sand go from little, single-media channels to advanced commercial systems. Garnet sand helps to expel suspended particles from chemical as well as water filtration process.

In light of its hardness, high gravity and the pounds per cubic foot, garnet sand, when used correctly, remains in its own particular layer holding down the layers underneath amid discharge. The layers over the garnet sand are lighter in weight (per cubic foot) and accordingly they lift during backwash and discharge the “floc” cleaning of the filter media. The Garnet sand is not used to replace silica sand but rather to support it. Garnet sand is so sturdy and substantial that the layers above will be renewed or replaced well before the garnet and filter rock layers are replaced. In this manner, time and cash are spared by utilizing garnet sand in a filtering framework.
