ANTHRACITE
ANTHRACITE
The Anthracite is a highly specialized filtration medium produced from high-grade, deep-mined anthracite coal. It is specifically selected for its high carbon content, low volatile matter, and exceptional structural hardness.
Unlike standard coal, filtration-grade anthracite is crushed and hydraulically classified to achieve a highly angular shape and a specific uniform particle size, making it ideal for trapping suspended solids.
Applications
- Dual-media filtration: Its lower specific gravity allows it to remain on top during filtration, effectively capturing larger particles and reducing turbidity.
- Multimedia filters: Can be combined with other filter media, such as sand, to create a multi-layered filter bed that enhances water clarity and efficiency.
- Industrial and drinking water: Suitable for various water clarification processes, including industrial and potable water production.
