Recently Completed Remediation Projects
Seattle, Washington:
Completed: October 2007
Our design: Dual Phase System using a high-vacuum rotary claw blower, treat the water with an oil/water separator and air stripper, and treat the off-gas with vapor phase carbon.
Restrictions: Located in downtown Seattle, Washington, required very strict space limits and noise constraints.
Solution: The design needed to be quiet and compact; we built up instead of out. Seneca fabricated a steel skid on the top of a 10-foot cargo container with an OSHA ladder and railing. This design allowed the carbon drums and control panel to be safely mounted on top of the building. Noise reduction was very important. The walls of the container were insulated with spray foam, sound board and two-inch noise foam. The rotary claw blower was noise protected with a sound enclosure with cooling fan and the heat exchanger ductwork was insulated.
Kansas City, Kansas:
Completed: October 2007
Our design: The 12-foot by 36-foot metal-sided building houses an SVE and Air Sparge system. The 150 horsepower SVE blower is designed to do 2,500 scfm @ 10” HG vacuum, while the 75 horsepower rotary screw air compressor does 375 cfm. We are also treating the off-gas with a thermal oxidizer.
