Sept. 21, 2009 -- Imbrium announced today that its innovative stormwater treatment product, SorbtiveFILTER, has received approval from the Maryland Department of the Environment (MDE) for stand-alone stormwater quality treatment throughout the state, including in the environmentally-vulnerable Chesapeake Bay region.
SorbtiveFILTER incorporates Imbrium's oxide-coated SorbtiveMEDIA to provide stormwater treatment with unprecedented phosphorus removal capabilities -- including dissolved phosphorus, a major cause of the algae blooms and reduced dissolved oxygen that threatens the Chesapeake Bay watershed.
The MDE performed an extensive review of SorbtiveFILTER and SorbtiveMEDIA's performance, including analysis of field and lab testing results, approving SorbtiveFILTER as a stand-alone device in addition to use in pretreatment, redevelopment and retrofit projects.
Rigorous field testing shows that SorbtiveFILTER captures 89% of sediment, 78% of total phosphorus, and an unprecedented 44% of dissolved phosphorus from stormwater runoff. It provides an excellent tool for addressing the stringent requirements in the current phosphorus-based Total Maximum Daily Loads (TMDLs), including the needed phosphorus load reductions to protect the Chesapeake Bay Watershed.
Other Key Approvals
SorbtiveFILTER and SorbtiveMEDIA have received other key reviews and approvals, including an in-depth review from the Massachusetts Stormwater Evaluation Project (www.mastep.net) and numerous other approvals in Virginia, where phosphorus is the primary pollutant of concern.
