Become an AFM Expert with these Water Treatment Webinar Series

The AFM® Webinar Series presents and discusses the Activated Filter Media – AFM® with it’s unique surface properties and benefits providing for a superior filtration performance. These webinars will significantly increase your knowledge in media filtration using AFM® in water treatment.

AFM® – Activate Filter Media

  • Direct replacement for sand in any type of sand filter.
  • Doubles the filtration performance of a sand filter by way of simple media change
  • AFM® will remove sediment down to 1 micron at 97% efficiency as well as dissolved organic components, heavy metals, hydrocarbons and microplastics.
  • Bio-resistant, will not support bacterial growth => no biofilm formation on AFM® surface.
  • Up to 50% reduction in backwash water consumption
  • Manufactured to a precise specification under ISO-9001-2015
  • NSF-61 certified for use in drinking water treatment
  • AFM® market proven performance >15 years without media replacement.
  • AFM® is a highly engineered product manufactured from a specific glass type to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to become self-sterilizing to offer superior adsorption properties.
