Anthracite

Anthracite is a hard, compact variety of mineral coal which is highly lustrous. It has the highest carbon content, the fewest impurities, and the highest calorific content of all types of coal, including bituminous and lignite coal. Anthracite is the most metamorphosed type of coal, wherein the carbon content ranges from 92.1% to 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. Anthracite is categorized into standard grade, which is used mainly in power generation. High Grade (HG) and Ultra High Grade (UHG), the principal uses of which are in the metallurgy sector.

FAQs About Anthracite

1. What is anthracite used for?
Anthracite is primarily used in water treatment processes as a filtration medium due to its high density, hardness, and ability to remove suspended solids from water.
2. How is anthracite different from other filtration media?
Anthracite has a higher carbon content and harder structure compared to other media, providing longer-lasting performance and more efficient filtration.
3. Can anthracite be used in combination with other filtration materials?
Yes, anthracite is often used in multi-media filtration systems alongside other materials like sand or gravel for improved filtration performance.
4. Is anthracite environmentally friendly?
Yes, anthracite is a natural filtration material and is often considered environmentally friendly because it can be recycled and reused in many applications.
5. How long does anthracite last in a filtration system?
The lifespan of anthracite depends on the application, but it typically lasts longer than other media, especially in high-flow or heavy-duty filtration systems.

Anthracite is a high-carbon, hard coal used as a filtration medium for water treatment systems. Its dense and hard nature makes it ideal for removing suspended solids from water, offering excellent mechanical strength and longevity. When used in multi-media filtration systems, anthracite can effectively trap larger particles, while the other filtration media remove finer particles. Anthracite is often combined with sand and gravel in a multi-layered filtration system to enhance performance and prolong the life of the system. With its environmentally friendly properties and durability, anthracite is the preferred choice for high-performance filtration. Western Chemical’s premium anthracite ensures reliable filtration in both industrial and municipal water treatment applications.
