Osram Sylvania is a leading manufacturer of lighting products for industrial, entertainment, medical applications, smart buildings, and more.
The Versailles, KY construction site generated approximately 160,000 gallons of stormwater runoff that contained elevated levels of lead (Pb) contamination. The stormwater was stored in temporary storage containers for processing. Local stormwater regulations dictated a discharge limit of <15 ppb Pb, and the client further imposed an internal limit of 10 ppb to ensure compliance.
The RO membranes initially used were quickly fouled and needed replacement, due to the high amount of total dissolved solids (TDS), and higher than expected lead concentration (>150 ppb) in the stored wastewater. Total costs for operating the RO system through the life of the project would have been cost-prohibitive, in excess of $100,000. Contracting for offsite disposal was also found to be cost-prohibitive, many times more than the aforementioned onsite treatment.
Solution: The ElectraMet™ System
SystemOsram Sylvania, KarSare, and the ElectraMet™ team worked quickly to deliver a fully automated 7 gpm ElectraMet system to replace the existing RO system in just one week. Over the course of the project, the system treated 160,000 gallons of stormwater runoff meeting all stormwater discharge requirements.
