How does it work?
It's angular to sub-angular particle shape provides a 30% improvement in turbidity removal over silica sand. It's non-porous composition means its less likely to clump or channel than silica sand. less susceptible to bio-fouling as unlike silica sand, EGFM's particles have a smooth surface area, so bacteria can't get trapped in any cracks or flaws. This translates to less remedial action and again less chemical treatment to kill pollutants.
