  • A primary rigid strainer constructed of a perforated material with surface area that accommodates flows rated at 125% of the flow of the basin prior to installation. 

  • Absorptive media section incorporates a flexible open mesh fabric envelope containing a specialized media blend. This envelope is suspended from the support assembly and fitted into the basin so all influent passes through it before exiting the filtration unit and entering the downstream conduit. The combination of gross solids removal via the strainer and the absorption / filtration function of the media section reduce TSS and other pollutants.

  • The support structure is a one piece pan that installs between the grate and the concrete or steel grate frame. The pan provides support for the filter element and the rigid  strainer and ensures all water passes through the strainer and filter.

  • With the unique, easy access sampling port, it’s easy to check system performance any time.
