Imbrium Systems Introduces SorbTIVE Engineered Media For Stormwater Pollutants

New stormwater pollutant absorption technology paired with versatility

Rockville, MD — Imbrium™ Systems introduces innovative absorptive multimedia for treating critical stormwater pollutants.

SorbTIVE has been engineered to capture and retain dissolved phosphorus and heavy metals such as zinc, cadmium, copper and lead from stormwater runoff through absorption and filtration. Phosphorus in stormwater runoff causes algae blooms, which reduces dissolved oxygen levels in natural water resources, leading to fish kills and degraded ecology. Heavy metals in runoff transport through the aquatic environment and bio-accumulate in natural food chains.

"This oxide-coated engineered media offers unrivalled pollutant removal capability and capacity," said Scott Perry, Imbrium Systems' Product Manager, who noted SorbTIVE's development included rigorous testing over a ten-year period.

"Conventional media used in stormwater treatment has been used to capture these same pollutants, however in a short time period they absorb, then desorb or leach - releasing pollutants," continued Perry. "Based on comparative testing, SorbTIVE has between 100 and 1,000 times the pollutant capacity. It's like comparing the capacity of a small coffee cup to a huge garbage can." And unlike organic or compost-type media such as peat, SorbTIVE does not decompose, so it never releases pollutants over time.

SorbTIVE can be used in various forms and applications. One specialty form is pea-sized, granular particles which give it a high specific surface area, allowing it to capture and retain a large pollutant load.

But that's just the beginning. SorbTIVE can be applied to a wide variety of low impact development applications such as pervious concrete. Or, it can also vastly improve the effectiveness of pre-existing proprietary and non-proprietary structural BMPs, like sand filters.

"This versatility makes SorbTIVE an effective solution for treating urban stormwater runoff, agricultural runoff and critical watershed management areas where the TDMLs (Total Daily Maximum Load) are administered, because of SorbTIVE's ability to deliver consistent effluent levels. This patented technology will raise the bar for improving stormwater quality."
