Anthracite coal (anthracite coal) is one of the many types of coal, it has the highest metamorphism. It is a hard, low impurity coal with the highest carbon and energy content of any coal. Anthracite is a sediment from the remains of ferns, primitive animal remains buried in swamps since prehistoric times, and cannot decompose in the air.

Characteristics of anthracite coal

• Physical properties: coal has relatively high strength, is brittle, hard, less likely to be broken during transportation

• Chemical properties: coal is less prone to change and the impact of some chemicals. Due to the hollow structure, the use of anthracite coal is often used to filter alum water, well water, and industrial wastewater.

• Charcoal appearance is black, metallic (sometimes multicolored due to light reflection)

• Anthracite coal is difficult to burn, does not self-ignite, so it can keep a large volume for a long time

• The ability to generate heat is many times greater than other coal lines

Application of anthracite coal

• After answering "is anthracite coal not coal", people have learned and applied in the mechanism of water purification, wastewater purification and for industries that need high calorific fuel.

• Has the ability to prevent clogging when bacteria Synedra, Mekocytin,… form.

• As a raw material for cement production, but due to low production (accounting for 1% of all types of sediments exploited) it is rarely used.

• Anthracite water purification model

• Anthracite coal water filter column
