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 never needs to be
recharged or replaced.
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 increase
its surface area by up to 300 times for superior mechanical and electro-static filtration performance.
The activated surface of AFM® is self-sterilizing which prevents bacteria mud-balling, coagulation
and channeling of unfiltered water through the filter bed. Activation increases the surface area
by up to 300 times for catalysis and adsorption reactions. Similar to activated carbon, the surface
nano-structure adsorbs pollutants from the water but unlike carbon, AFM® is recharged by just
back-washing with water.
