AFM
AFM® Activated Filter Media is a direct replacement for sand, doubling the performance of sand filters without the need of additional investments in infrastructure. AFM® resists biofouling, biocoagulation and transient wormhole channeling of unfiltered water and outlasts all other filter media.
✓ AFM® is a highly engineered product manufactured from a specific glass type, processed to obtain the optimum particle size and shape. It is then exposed to a 3-step activation process to become self-sterilising and to acquire superior adsorption properties. During activation, the structure and the chemistry of the glass are modified.
AFM® benefits at a glance
✓ More than doubles the performance of an existing filtration system
✓Is not subject to biodynamic instability and will never allow untreated water to pass
✓Substantially lowers chlorine oxidation demand
✓Lowers backwash water demand by an average of 50%
✓Is expected to last for the life of the filtration system
✓Provides quick return on investment
Self-sterilizing surface
Unique 100% bio-restistant filter media
When in contact with water flowing through the filter, a small amount of free radicals (O and OH) are formed on the surface of the grains. Thanks to their strong oxidation potential, free radicals protect AFM® from colonisation by bacteria and fully prevent the formation of biofilm.
