Filtration Media 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.

Certified to NSF/ANSI/CAN Std. 61
  Larger particle size creates less pressure loss, higher sediment loading, and longer filter runs  
  Light weight provides lower backwash rates and better bed expansion  
  High sediment reduction capacity  
  High service rates result in lower equipment costs  
  Certified to NSF/ANSI/CAN Standard 61
