Products Description
Anthracite Coal Filter Media is a high-strength filter medium used in industrial and municipal water treatment. It features strong dirt-holding capacity, fast flow rate, and low backwashing requirements, which can significantly improve filtration stability and operating efficiency.
High filtration efficiency: The rough particle surface and large specific surface area (350–450 m²/g) result in strong retention capacity, effectively controlling effluent turbidity to <1 NTU.
Low backwashing frequency: Moderate density (1.4–1.6 g/cm³) and hard, non-breakable particles reduce backwash water consumption by 20–30%.
High abrasion resistance: Utilizes high-purity anthracite with a fixed carbon content of 85–90%, resulting in high hardness and low abrasion rate.
Raw Materials and Production Process
Raw Materials: High-purity anthracite coal from deep mining areas, with fixed carbon ≥85%, low ash content, and few impurities, ensuring stable filtration performance.
Process: Complete processing from crushing to fine screening, washing, drying, and magnetic separation; particle size control accuracy up to ±0.2 mm, ensuring uniform laminar flow.
Equipment: Automatic screening system, drying furnace, magnetic separator, and dust removal equipment, supporting stable large-scale production.
Testing: Particle size, density, abrasion rate, and mud content are tested according to AWWA B100 and NSF/ANSI standards, ensuring batch stability and traceability.
Packaging and Storage
Packaging: 5kg bags / 500–1000kg ton bags, customizable.
Storage: Store in a dry, well-ventilated place, avoiding moisture.
Transportation: For sea freight, an inner moisture-proof bag can be added to maintain granule strength and cleanliness.
FAQ
Q: What are the standard particle sizes?
A: 0.6–1.2mm, 1.2–2.5mm, 2.5–5mm; custom sizes are available upon request.
Q: Which industries are suitable for?
A: Drinking water, deep wastewater treatment, power generation, chemical industry, and industrial circulating water filtration systems.
Q: What is the service life?
A: Under normal conditions, it can last 3–5 years. Due to its high hardness, it is not easily pulverized.
Q: What is the supply capacity?
A: Monthly production capacity is 3000–5000 tons. We support engineering projects and long-term wholesale supply.
Q: Are there any testing and certifications?
A: AWWA B100, NSF/ANSI standards, and third-party testing reports are available.
Q: Will it absorb moisture during transportation?
A: The ton bag is film-coated, and an optional moisture-proof liner ensures stability during long-term sea transportation.
