Anthracite is filter material for water purification, produced by crushing and sieving natural anthracite coal. The abrasion-resistant material grains are characterized by their sharp-edged surface structure and a chipped grain form.

A wide selection of anthracite is available; at different grain sizes, depending on the water treatment processes, i.e. Pre-treatment/Filtration, Precipitation/Iron and Manganese Removal, Softening/Decarbonisation and Neutralisation.

Pre-filtration Media:

This product is proposed as an alternative to the commonly installed anthracite filtration media.

The advantages include:

  • Less than half the density of normal anthracite which translates to significantly reduced backwash rates
  • Lower backwash rates which requires smaller pumps and less backwash water
  • High capacity for ion removal
High-Purity Anthracite:
  • High purity
  • Mined from very deep mines which translates to a very hard product
  • Low ash contact
  • Drinking water approved

With over 35 years of experience, UDEC is the innovative industry leader and specialist in process materials, speciality chemicals and adsorbents.
