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 is a lightweight media built from a Perlite base that removes total phosphorus (TP) by adsorbing dissolved-P and filtering particulate-P simultaneously.
Perlite is expanded volcanic rock. Its porous, multi-cellular structure and rough edges make it effective for removing TSS, oil and grease.
A granular organic media created from deciduous leaves, CSF is most effective for removing soluble metals, TSS, oil and neutralizing acid rain. MetalRx, a finer gradation, is used for higher levels of metal removal.
A naturally occurring mineral used in a variety of water filtration applications, is used to remove soluble metals, ammonium, and some organics.
GAC 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.
A proprietary blend of zeolite, perlite, and GAC to improve the performance of perlite and target organics, soluable metals and other pollutants.
