WaterTectonics was contacted by Schnitzer Steel for assistance in reaching stormwater discharge benchmarks for their 40 acre recycling yard in Portland, OR. They were interested in reducing aluminum, cadmium, chromium, copper, iron, lead, nickel, zinc and total suspended solids (TSS) from their stormwater. A treatability study was completed in 2012 with a pilot taking place in 2013 to further verify the design approach. WaterTectonics designed, delivered, mobilized and commissioned a multi-stage 600gpm WaveIonics treatment system consisting of electrocoagulation, clarification, filtration and carbon polishing. An Automated Operator system incorporated control and adjustment of all system processes to a single touch-screen interface, and a water quality discharge valve was utilized to ensure that all effluent water met operator-defined turbidity and pH standards prior to final discharge.
