Water Treatment Systems for Total Fluid
& Dissolved Phase Hydrocarbons

Groundwater treatment technologies rely on physical, chemical, and/or biological processes to reduce contaminant concentrations to acceptable levels. When multiple contaminants are present, some technologies may be excluded as complete solutions, but considered as a pretreatment or polishing step in a 'treatment train'.

Air stripping and granular activated carbon (GAC) units may be used to remove organic compounds from groundwater during aquifer tests. Air stripping is generally more cost-effective than GAC for treating volatile organic compounds when flow rates exceed 3 gpm, but may require additional vapor phase treatment.

Geotech Oil/Water Separators

Oil/Water Separator

Geotech Oil/Water Separators are designed to separate oil, light petroleum products, and oily-coated solids from water with 99.9% efficiency. The separator is comprised of a tank with inlet, separation chamber, sludge chamber, and clean water outlet- all constructed from 12-gauge stainless steel.

  • Professional lined for superior corrosion resistance
  • Marine-grade aluminum vapor control covers
  • Non-clog inlet with diffuser for even distribution across separator chamber
  • Compatible with Geotech positive displacement pump or gravity feed
  • Built in underflow weir to control settled solid from redistributing
  • Meets EPA Method 1664 Rev. A and EU EN 858-1 Standards
