Only the Eljen GSF
Pretreats Effluent with a
Patented Two-Stage Bio-Matt™
When your installation requires extra
capacity in less space, the Eljen GSF delivers.
While conventional systems rely on a single biomat
forming at the soil interface, the Eljen GSF adds a second,
primary biomat layer on the surface of its unique Bio-Matt™ Fabric.
