ADVANTAGES
There is less pressure loss through a bed of Filter-Ag® than through most other filter medias

Light weight requires lower backwash rates than those required for other filter medias

High service rates result in lower equipment costs and a savings in space

High sediment reduction capacity results in longer filter runs, with a substantial savings in backwash water and time out of service

Reduced shipping cost due to light weight/cu.ft.

Replacement of sand with Filter-Ag® in existing installations may increase filter capacity 100% or more. (Caution should be taken upon start-up that the lightweight Filter-Ag® is not washed to drain.)
