Dissolved Phase and
Total Fluid Hydrocarbon
Remediation Equipment

Dissolved Phase Contaminants — The part of (VOCs-hydrocarbon) contamination which has dissolved/partitioned into a body of water (In our case – groundwater and typically petroleum based compounds).

When hydrocarbon product is present in the dissolved phase in groundwater extraction wells, the contaminated groundwater must be treated. Geotech has the equipment for pump-and-treat systems. Pump and treat is a common method for cleaning up groundwater contaminated with dissolved chemicals, including industrial solvents, metals, and fuel oil.

Total Fluids Extraction – The removal/recovery of groundwater (usually contaminated with dissolved phase contaminants) along with any free phase product; such as gasoline and groundwater contaminated with gasoline that has portioned into it. Chlorinated solvents could also fall into this category.

Total fluids recovery systems generally require LNAPL/water separation which may be difficult due to emulsification. Emulsification problems can be minimized by proper pump selection.

Pneumatic Remediation Pumps Pneumatic Remediation Pumps

Pneumatic remediation pumps that pump to the surface dissolved hydrocarbons, leachate and condensate. They are built to withstand highly corrosive fluids in harsh down-well environments.

Advantages for using pneumatic remediation pumps:

  • Intrinsically safe for hazardous environments
  • Controller-less pumps available
  • Systems can be solar-powered

Pneumatic Pump Controls Transducers and Control Panel

Geotech offers a variety of pressure transducers and controllers for groundwater monitoring, remediation pump control, landfill pump control, and many other applications.

Water Treatment Systems Oil-Water Separator

Treatment systems for the separation and removal of dissolved phase hydrocarbons from groundwater at the surface.

Electric Submersible Remediation Pumps Electric Submersible Pump

Electric pumps that pump polluted water to the surface for treatment.

Advantages for using electric submersible pumps:

  • Users have the capability to change the pump performance while the pump is installed in the well
  • Efficient remediation to depths of 524 feet (160 m)
  • Flow rates of up to 45 GPM (170 LPM)
  • Ideal for continuous operation in remediation applications

Top-Head Drive Piston Pumps Blackhawk Atlas Pumps

Blackhawk Piston Pumps

Blackhawk positive-displacement reciprocating-piston pumps are powered by electricity, pneumatic air or solar panels.

The all-weather drive motors and stuffing boxes are cleanly and safely outside the well or sump. Because motors and mechanicals can be roughly two-thirds of a pump's cost, the principal investment is secure from downhole loss.
