Cost and Pollutant Reduction Benefit for and Industrial Stormwater Treatment System
This technical presentation will describe full scale implementation of four advanced treatment systems for industrial storm water from a 7-acre industrial facility. The four systems each treat between 400 and 800 gallons per minute using flow balancing, grit/oil separation, biopolymer flocculent addition, solids settling, and sand filtration. Two years of operating data show >95% pollutant reduction in over 5 million gallons of storm water and 100% compliance with numeric action levels contained 2014 Industrial General Permit. The presentation will focus on describing when active treatment is appropriate, regulatory approvals, treatment efficiency in terms of dollar-cost per pound of pollutant removed, and construction and operational challenges associated with large-scale, active industrial storm water treatment.
