Filter Media Options

Our filtration products can be customized using different filter media to target site-specific pollutants. A combination of media is often recommended to maximize pollutant removal. More information is available in the StormFilter Configuration Guide.

PhosphoSorb®

PhosphosorbPhosphoSorb is a lightweight media built from a Perlite base that removes total phosphorus (TP) by adsorbing dissolved-P and filtering particulate-P simultaneously.

Zeolite

ZeoliteA naturally occurring mineral used in a variety of water filtration applications, is used to remove soluble metals, ammonium, and some organics.

Granular Activated Carbon (GAC)

Granular Activated CarbonGAC has a micro-porous structure with an extensive surface area to provide high levels of adsorption. It is primarily used to remove oil and grease and organics such as herbicides and pesticides.

ZPG™

ZPG MediaA proprietary blend of zeolite, perlite, and GAC to improve the performance of perlite and target organics, soluable metals and other pollutants.
