Activated carbon media supplies for water treatment

Hydro-Anthracite Media N 0.6 – 1.6 mm 25kg

£52.00

Hydro-anthracite works as a physical filtration medium. It removes impurities from water mainly by straining and depth filtration, not by chemical reactions.

  • Water flows through a deep, porous bed, water enters the filter and flows downward through a packed bed of hydro-anthracite grains. These grains are hard, irregular in shape and relatively large compared to sand. This creates lots of void spaces between particles.
  • Particles get trapped, as water moves through the bed larger particles get trapped near the top and smaller particles penetrate deeper and get caught further down. This is called depth filtration, and it’s why hydro-anthracite can hold more dirt before clogging compared to fine sand.
  • Low density equals solids are captured more effectively. Hydro-anthracite has a lower density than sand, which means, it sits on top in multimedia filters and it allows higher filtration rates, solids distribute throughout the bed instead of forming a surface cake. Resulting in longer filter runs and less pressure drop.
  • Minimal chemical interaction. Hydro-anthracite is chemically inert and very low in ash and impurities, so it doesn’t leach contaminants into the water. It’s removing solids physically, not absorbing chemicals like activated carbon does.
  • Backwashing cleans and resets the bed. When the filter gets dirty water (sometimes air + water) flows upward, the bed expands and fluidizes, trapped solids are released and flushed away

Features

  • Superior filtration performance
    Its high carbon content and angular grains trap suspended solids very efficiently, reducing turbidity.

  • High porosity = higher flow rates
    Water passes through more easily than sand, allowing higher filtration rates with less pressure drop.

  • Longer filter runs
    It can hold more dirt before clogging, so filters operate longer between backwashing cycles.

  • Excellent backwash characteristics
    Lower density than sand means it expands well during backwash, cleaning thoroughly and evenly.

  • Very durable material
    High hardness and low attrition prevent breakdown, giving it a long operational life.

  • Chemically inert
    Stable in a wide pH range and resistant to chemicals commonly used in water treatment.

  • Ideal for multi-media filtration
    Works perfectly in dual-media or multimedia filters (often layered above sand or garnet).

  • Improves overall water quality
    Helps remove turbidity, suspended solids, colour, and particulate contaminants.

  • Steel Production: Hydro anthracites serve as a clean, high-energy fuel in blast furnaces, improving efficiency and reducing emissions. For example, steel manufacturers use them to achieve higher purity in their processes.
  • Water Filtration: Due to their porous surface and high purity, hydro anthracites are used as filtration media in water treatment plants, removing contaminants effectively and sustainably.
  • Activated Carbon Production: Their high carbon content makes hydro anthracites ideal raw materials for producing activated carbon, which is used in air purification and chemical processing.
  • Energy Generation: Some industries utilize hydro anthracites as a cleaner alternative to traditional coal in thermal power plants, aiming to reduce environmental impact.
