What characteristic makes Anthracite particularly useful in water treatment?

• A. Its ability to dissolve contaminants
• B. Its high carbon content and low volatile matter
• C. Its affordability and availability
• D. Its thermal conductivity

Answer: (B)

Anthracite is particularly useful in water treatment primarily due to its high carbon content and low volatile matter. This characteristic allows anthracite to serve effectively as a filtration medium. The high carbon content provides a large surface area for adsorption, which is crucial for capturing and retaining impurities, including organic matter and other contaminants in water. Additionally, the low volatile matter means that anthracite burns cleanly and produces minimal ash, which can affect filtration efficiency and maintenance of the filtration system.

The effectiveness of anthracite as a filtration material contributes significantly to improving water quality by reducing turbidity and removing particulates. Its performance in water treatment applications is enhanced by its physical properties, such as its durability and ability to maintain a stable bed structure in filtration systems.
