Pollutants addressed include bacteria, TSS, nutrients, oil & grease, phosphorus, metals, as well as other pollutants. In addition, the plants in this system remove pollutants from stormwater by adsorption. FocalPoint High Performance Modular Biofiltration System – This high-flow biofiltration system acts as a pretreatment LID chamber, reducing pollutants from discharges before entering the Navy’s structural BMP.Gabion Barrier – This prevents larger debris from entering the system’s filter media beds.The FocalPointEMR system is comprised of three main parts: This system combines technologies to meet stringent water quality standards while also reducing the processing times, footprint, and cost required for treatment. To help solve this challenge, US Navy engineers spent 10 years and tested dozens of optional media options to develop FocalPointEMR, a LID/BMP hybrid system that decreases the concentration of toxic contaminants to meet National Pollutant Discharge Elimination System (NPDES) permit requirements.įocalPointEMR is a modular system that combines several types of filtration media to remove pollutants from NPDES stormwater discharges. Facilities are challenged due to intense operations with heavy equipment, multiple pollutant sources, nonporous paved surfaces and buildings, storage areas, and aging drainage and stormwater management technologies. Most industrial facilities are under increasing pressure from regulators and local communities to protect harbors, bays, lakes, and streams by reducing the elevated concentrations of environmental pollutants commonly found within their facility’s stormwater runoff. Developed by the US Navy, FocalPointEMR is a green stormwater infrastructure system that eliminates harmful metals, nutrients, TSS, oil, and grease from industrial site runoff.
