FocalPointEMR Technical Data Sheet
NAVFAC Engineering and Expeditionary Warfare Center (EXWC) engineers developed a hybrid Low Impact Development (LID) / Best Management Practice (BMP) multi-media filter, the FocalPointEMR, to remove heavy metals from industrial site stormwater. Navy industrial sites are under increasing pressure from regulating bodies to reduce stormwater pollution. Industrial activities, roofing and fencing contribute to elevated levels of zinc and copper in local receiving waters. These heavy metals are toxic to marine life at low levels and bio-accumulate, traveling up the food chain from marine organisms to fish to humans in greater and greater concentrations. EXWC evaluated over 25 heavy metal adsorbing media and pre-filtration technologies, selected the most effective ones, and demonstrated and validated a this hybrid system with exceptional metal removal efficiencies.
