Filter Ag
Filter Ag is a very efficient filter medium for the removal of suspended material and turbidity. Less pressure loss and finer filtration is possible because of its light weight and irregular surface characteristics.

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.
