Oil-Water Gravity Separation with Clara

Clara (klar-uh) is a patented† oil-water gravity separator for industrial stormwater treatment. This below-ground, standalone system removes dirt, oil and floatables by gravity separation. Clara is recommended when suspended solids are greater than 200 mg/L and oil is greater than 10 mg/L. With the built-in internal high flow bypass, pollutants are trapped in this below-ground structure even during peak runoff events. For more complete pollutant removal, Clara can be installed in a treatment train with Aquip and Purus.

Clara Features

  • Traps pollutants within the system
  • Removes floatable materials, oil and dirt
  • Treatment flow rates of up to 1400 gpm
  • Oil storage capacity of up to 820 gallons
