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.

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.
Recommended operational parameters
| Parameter | Value |
| Filtration velocity | 1-15 m3/hr/m2 |
| Back Wash velocity | 35-55 m3/hr/m2 |
| Max. operating differential pressure | > 0.4 bar |
| Back Wash Duration | 5 - 10 mins |
| Water pH limits | 3 - 9 |
| Water temperature limits | 1-100 ° C |
IMPORTANT NOTE: Before first use of AGFM backwash the media for 10 – 15 minutes 3 consecutive times with potable water and then rinse it for a further 1 hour.
