Riley Equipment Company supplies high-quality anthracite filter media designed for use in water treatment systems and industrial filtration processes. Sourced from superior-grade coal and processed under tightly controlled conditions, our anthracite filter media delivers excellent filtration efficiency and long service life. With a higher service flow rate compared to many other filter media types, anthracite is a reliable solution for both rapid, high rate and multi-media filtration applications. This media is a type of Liquid Phase Carbon Media.
As a trusted anthracite filter media supplier, RECO provides consistent, unactivated coal-based media ideal for liquid-phase filtration. Its uniform hardness and angular shape make it highly resistant to breakdown, which results in lower pressure drop, reduced backwash frequency, and greater operational efficiency.
Features & Benefits of Anthracite Coal Filter Media
Anthracite media is known for its durability, high carbon content, and superior filtration performance. It plays a critical role in removing turbidity, suspended solids, and other particulates from raw water, wastewater, and process liquids.
Key advantages include:
- High flow capacity and low head loss
- Extended media life with minimal attrition
- Chemical resistance in varied pH environments
- Effective solids retention and turbidity reduction
- Suitable for use in gravity or pressure filters
Thanks to its physical strength and natural filtering ability, anthracite coal filter media is a preferred option for operators seeking a low-maintenance, high-performance solution.

Applications for Anthracite Filter Media
Riley’s anthracite media is widely used in municipal and industrial water treatment systems. It serves as a coarse filtration layer in rapid sand filters and multi-media filters, helping remove large solids and protecting downstream filtration stages such as activated carbon.
Common applications include:
- Potable water treatment
- Wastewater clarification
- Pre-filtration before activated carbon beds
- Industrial process water purification
- Cooling tower filtration systems
Outside of water filtration, anthracite media is valued in power generation and heating applications for its high fixed carbon content and combustion properties.
Anthracite Media vs. Activated Carbon
While both anthracite and activated carbon are carbon-based filtration materials, their functions differ significantly. Activated carbon is used for adsorbing dissolved organic compounds and chemicals. Anthracite media, on the other hand, provides physical filtration of suspended particles. The two are often used in sequence—anthracite first for particulate removal, followed by activated carbon for chemical polishing.
Anthracite media for water filtration is a cost-effective and proven choice for systems where efficient sediment removal is essential before chemical treatment.
