swtwater.com Filter-Ag® Filtration Media
Particulate Reduction Media
Filter-Ag (P/N 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 the 20 to 40 micron range.
