Mobile Dual-Phase Extraction (MDPE)

EE&G, Inc. currently owns and operates a fleet of MDPE trailers. The trailers simultaneously extract liquid and vapor from the subsurface under high vacuum. Upon retrieval from the subsurface, liquid and vapors enter a knockout chamber that separates the two. Liquid is either transferred to storage containers for off-site disposal or routed through EE&G’s water treatment units/trailer for final discharge. Effluent vapors are treated to below applicable permit standards using electric catalytic oxidizers and subsequently discharged to the atmosphere.

Advantages

  • Mobile Units — all units are trailer mounted and can target multiple portions of the contaminant plume(s) during events
  • High Vacuum — negative vacuum pressures can reach as high as 28 inches of mercury, thus promotes VOC recovery from most geological settings
  • Portable Power Source — all trailers run via portable generators
  • Enhanced Vapor Recovery — adds Non-Aqueous Phase Liquid (NAPL) to recovery volumes
  • Natural Attenuation of contaminant plumes
  • Eliminates Long Term, Onsite Maintenance Costs — the all-inclusive mobile unit negates fixed system maintenance costs
  • Eliminates Decommissioning Costs
  • Large Radius of Influence — most geological settings
  • High Efficiency — 300–600 SCFM oxidizers
  • Adjustable Groundwater Production — drawdown can be adjusted to accommodate remediation goals and specific hydrogeological needs
  • Existing Monitoring/Recovery Well Utilization — units can accommodate monitor wells from 2–6 inches in diameter as extraction points
  • Small Footprint with No Disruption of Business — most units require as little as two parking spots to operate; active businesses can remain open and produce revenue during remediation operations
  • Setup Time — MDPE systems can be set up and recovering VOCs in as little as one hour
