StormwateRx LLC designed and supplied stormwater treatment BMPs for two main outfalls of a 25 megawatt biomass-fired power plant located on a 50-acre industrial site near Sacramento, California.
After qualifying other technologies and systems on the basis of performance, cost, and installation base, the plant was retrofit in 2009 with a StormwateRx LLC Clara® 90CP plug flow separator system and an Aquip® 210SBI stormwater filtration system to reduce stormwater pollutants from the main plant outfall. The systems were retrofit to an existing outfall in a treatment train configuration with Clara followed by Aquip.
A second outfall draining runoff from the biomass feedstock stockpile area has been retrofit with a low profile Aquip® 200CIL stormwater filtration system. The Clara plug flow separator and Aquip filtration systems work in tandem to remove pollutants by gravity separation and filtration, respectively. The Aquip SBI filtration system includes an internal passive mineral buffering process to condition the stormwater and promote more effective removal of oil, organics and metals through the inert filtration media bed. The Aquip CIL filtration system promotes infiltration of runoff before filtration of excess runoff prior to discharge.
After qualifying other technologies the plant was retrofit with a state-of-the-art stormwater treatment system from StormwateRx LLC.
In conjunction with other source control BMPs, the StormwateRx treatment system reduces discharges of stormwater pollutants including total suspended solids (TSS), specific conductance, oil and grease or total organic carbon (TOC), biochemical oxygen demand (BOD), chemical oxygen demand (COD), copper, iron, lead, zinc, aluminum, arsenic, and chromium. The combination of Clara and Aquip plus other site BMPs qualify as Best Available Technology and Best Conventional Pollution Control Technology (BAT/BCT) for this industry sector.
