Filter Ag granules have irregular surface characteristics affording maximum removal of suspended matter throughout the filter bed. Filter-Ag can be applied to systems designed for either pressure or gravity flow.

Filter-Ag has many outstanding advantages over the more common granular filter media used for suspended solids removal. A substantial savings can be realized with Filter Ag because equipment can be smaller, requiring less square footage. Filter-Ag is a lightweight substance which means additional savings in backwash rates. Filter-Ag typically removes the normal suspended solids, down to 20-40 micron range.

Advantages	Physical Properties	Conditions for operation
There is less pressure loss through a bed of Filter-Ag than through most other filter media. Light weight requires lower backwash rates than those required for other filter media. High service rates result in lower equipment costs and a savings in space. High dirt removal capacity results in longer filter runs, with a substantial saving in labor cost, backwash water and time out service. Reduced shipping cost due to light weight/cu.ft. Replacement of sand with Filter-Ag in existing installations often increases filter capacity 100% or more.
