Activated Glass Filtration Media (AGFM)
Activated Glass Filtration Media replaces traditional sand media in all filtration applications. It is manufactured from a specific glass type and processed to obtain the optimum particle size and shape, and then activated to increase the surface area by 300 times over crushed glass or sand. The high surface area is negatively charged (zeta potential) to electro-statically attract organics and small particles. It also has permanent metal oxide catalysts, creating a high redox potential, to make AGFM self-sterilizing.
Main Benefits
- Over 30% lower running costs vs sand
- Over 50% lower chlorine consumption and lower disinfection by-products vs sand
- Filtration down to several microns at 100% efficiency without filtration aids
- More than 4 times longer lifecycle than sand Specifically engineered product, targeted for an efficient removal of priority metal oxides and other target constitutes
- Guaranteed prevention of channeling & biological fouling on the AGFM surface

How to use AGFM
AGFM is a direct replacement for sand in your media filters. Our media has a 15% lower density than sand by weight. This means you will require less of our media by weight than the equivalent sand.
