Stormwater BMP Products has a catch basin insert that now makes it possible to deploy either BiocharBASIC™ or BiocharPEAT™ filter medias for heavy metals removal in your catch basin. The uniquely designed ADSORB-it Catch Basin Filters are made from a hi-strength stainless steel frame attached to a heavy-duty screen basket with hi-flow ADSORB-it filtration fabric material that allows storm water to flow through the fabric material for extended periods while capturing sediments, oils, oily sheen and oil-borne contaminants.
Custom built to fit your catch basin, they are long-lasting, easy to clean, and easily replace the filter media for heavy metals as needed. Our filter medias are organic, easy to maintain and affordable.
Manufactured by Stormwater BMP Products, the Catch Basin Screen Basket Filters to collect and filter out large amounts of trash, debris and heavy sediment buildup for use in Industrial Facilities, construction sites and timber production yards that typically generate large amounts of solids and debris.
The Filter Screen Basket has a heavy-duty stainless steel frame and the steel screen basket section is vinyl coated for anti-corrosion. Now with the addition of either filter media you can easily reduce heavy metals at the catch basin.
Options available include ADSORBIT® Filter Liner, test port and Sediment Inlet Filter Cap.

"We got our first test results back last week. First time ever, we PASSED !!
The Zinc is what we have never passed. December was .209 mg/L and with new filter we had .049 mg/L. Way below state standard."

"Wanted to thank you for your help. Our Site passed its turbidity test with flying colors.
Our consultant said it was easy to sample and was impressed. Turbidity was only 11.5 NTU!"
(Results were after installing a custom catch basin insert.)
