Buy Premium Anthracite Filter Media in Kenya | Phynetech Water Filtration Solutions
Product Overview
Anthracite Filter Media is a high-purity, crushed hard coal specifically selected and graded for water purification. Recognized for its unique angular shape and high carbon content, anthracite is the “smart choice” for high-performance filtration systems. Unlike traditional sand, anthracite’s jagged structure creates larger voids within the filter bed, allowing it to trap significantly more debris deep within the media rather than just on the surface. It is the perfect filter media for this job.
In modern water treatment, anthracite is typically used as the top layer in dual-media or multi-media filters. Because it is lighter (lower density) than sand, it naturally stays at the top during backwashing. This layering creates a “coarse-to-fine” filtration gradient, where larger particles are caught by the anthracite at the top and finer particles are captured by the sand below. This setup results in longer filter runs, higher flow rates, and crystal-clear water.
Applications in Kenya
Anthracite is the preferred choice for Kenyan industries and municipalities facing high-turbidity water challenges.
- Municipal Water Treatment: Extensively used in large-scale plants across Nairobi and Kiambu to clarify surface water from dams and rivers.
- Borehole Water Polishing: Effectively removes the fine silt and suspended solids common in boreholes across the Rift Valley and Kajiado.
- Reverse Osmosis (RO) Pretreatment: A critical stage for industrial RO plants to prevent premature membrane fouling, extending the life of your equipment.
- Swimming Pool Filtration: Ideal for commercial pools in hotels and schools, providing superior clarity and reducing the frequency of backwashing.
- Wastewater & Effluent Treatment: Used as a final polishing stage to remove residual organic matter and insoluble contaminants before discharge.
How to Choose the Right Anthracite Media

To maximize efficiency, the media must meet strict technical standards:
- Fixed Carbon Content: Look for high fixed carbon (typically 80%–90%) to ensure chemical stability and resistance to degradation.
- Effective Size (ES): Choose a size that complements your sand layer. Common sizes include 0.8–1.6mm and 1.2–2.4mm.
- Uniformity Coefficient (UC): A UC of 1.7 or lower ensures a uniform bed that prevents “channeling” and ensures consistent filtration across the entire surface.
- Hardness: High-quality anthracite must be abrasion-resistant to withstand the high-pressure turbulence of repeated backwashing cycles.

Anthracite Media: Frequently Asked Questions
- Q: Why is anthracite better than sand alone? A: Anthracite has a larger dirt-holding capacity. In a dual-media filter, it allows for higher filtration speeds and longer periods between backwashes compared to a sand-only filter.
- Q: Does anthracite remove chemicals from water? A: While it is a carbon material, anthracite is used for physical filtration (turbidity removal) rather than chemical adsorption. For chemical removal (like chlorine), Activated Carbon is required.
- Q: How long does anthracite media last? A: Due to its high mechanical strength, anthracite typically lasts between 5 to 10 years with proper maintenance and backwashing.
- Q: What happens during backwashing? A: Because anthracite is lighter than sand, the backwash water lifts and expands the anthracite layer, flushing out trapped dirt while ensuring the anthracite stays on top as the bed resettles.
- Q: Can I use anthracite in a standard sand filter tank? A: Yes, you can convert a single-media sand filter to a dual-media filter by replacing the top third of the sand with the appropriate grade of anthracite.
