Anthracite filter
Overview
Anthracite filter media is a premium, coal-derived filtration material sourced from high-quality anthracite coal deposits. It serves as an essential component in water and wastewater treatment systems, effectively removing suspended solids, turbidity, and organic matter. With its angular structure and high density, it provides superior filtration efficiency while maintaining compliance with international standards such as AWWA B100 and NSF/ANSI 61. Ideal for B2B buyers in municipal, industrial, and commercial sectors, this media enhances water clarity and purity without the need for excessive chemical additives.
Key Features
- High Carbon Content: Typically exceeding 90%, ensuring durability and resistance to breakdown during extended use.
- Low Uniformity Coefficient: Ranging from 1.3 to 1.7, promoting a uniform bed for consistent flow and reduced channeling.
- Angular Particle Shape: Enhances particle retention and minimizes dust, contributing to cleaner operations.
- Chemical Stability: Low solubility in acids and alkalis (<1%), making it suitable for varied water conditions.
- Certification-Ready: Conforms to global benchmarks for safety and performance in potable water systems.

Applications
Anthracite filter media is versatile for:
- Potable water treatment in municipal plants, where it aids in clarifying drinking water by capturing fine particles.
- Wastewater clarification in industrial settings, reducing turbidity and suspended solids.
- Pre-filtration before activated carbon or other advanced treatments.
- Multi-media filter beds for enhanced efficiency in high-flow systems. It performs well in regions with stringent water quality regulations, such as North America and Europe, adapting to local needs like corrosion resistance in acidic waters.
Advantages
- Operational Efficiency: Offers higher service flow rates (up to 5 gpm/sq. ft.) and longer runs between backwashes compared to sand filters, potentially reducing water usage by 20-40%.
- Cost Savings: Durable structure extends media lifespan, minimizing replacement frequency and maintenance costs.
- Environmental Benefits: Low dust generation and efficient particle capture support sustainable water management practices.
- Customization Potential: Available in various sizes to meet specific project requirements, enhancing buyer decision-making. While advantages are evident in standard applications, outcomes can vary based on system design and water source quality.
