WaterTectonics worked as part of a multi-vendor team to design and implement this 100gpm WaveIonics electrocoagulation stormwater treatment system for Schnitzer Steel, a global leader in the metals recycling industry, in Woodinville, WA. As part of an extensive site improvement and upgrade plan, WaterTectonics was approached for providing equipment and services related to water treatment at the facility. In addition to two 790gpm oil/water separators, WaterTectonics also provided a 100gpm WaveIonics stormwater treatment system and was included in the design discussions surrounding conveyance, detention, and treatment of all site stormwater. As an active scrap recycling facility, Schnitzer anticipated that treatment measures beyond traditional BMP’s would ultimately be needed in order to meet discharge standards for the Industrial Stormwater General Permit (ISWGP). Further, with activities at the facility expected to ramp up, the client needed a system that could accommodate heavy pollutant loadings in stormwater runoff and be able to perform consistently even when characteristics of stormwater runoff fluctuated. With extensive real-time automation and water quality controls, the WaveIonics system is able to identify and adapt to fluctuating conditions in the influent water stream and still produce a similar quality effluent. The entire process is controlled by a discharge valve that monitors effluent water for pH and turbidity as a final check to ensure that water quality meets all user set parameters prior to discharge.
