iSOC® Passive Gas Infusion System

Tersus Environmental represents the inVentures Technologies Incorporated line of passive gas infusion technologies.  iSOC®, in situ Submerged Oxygen Curtain, is an oxygen delivery technology that when suspended in existing monitoring wells infuses high levels of oxygen into groundwater. The proprietary structured polymer used in iSOC® contains hydrophobic microporous hollow fiber. These fibers provide approximately 7,000 square feet of interface area per cubic feet of fiber for the mass transfer of oxygen into groundwater. 

iSOC® Passive Gas Infusion System

Most conventional technologies, however, waste most of their oxygen because the bubbles rise to the top of the groundwater table and escape before they have a chance to dissolve or to be utilized by naturally occurring hydrocarbon degraders.

Major Applications

  • Hydrocarbons
  • Vinyl Chloride
  • Ammonia
  • 1,4 Dioxane

Features and Benefits

 iSOC® Advantages:

  • Delivers 40-200 PPM DO depending on groundwater characteristics and iSOC® depth;
  • Uses existing 2-inch monitoring wells for installation;
  • Connects to standard oxygen cylinder;
  • No power, off-gases, pumps, hazardous by-products, or permit; and
  • Small, simple, efficient, predictable, easy to use, and very low maintenance.


  • Use to treat source, polish off sites or to stop off-site migration;
  • Will infuse any gas (oxygen, propane, methane, hydrogen and ethane); and
  • Can be used for cometabolic treatment (with alkane gases).


  • No moving parts and no electricity; and
  • Easily moved to a new injection point or new site.


  • Annual cost of oxygen for 3- iSOC®s is less than $250.00 a year;
  • Lowest annual O & M of any competitive technology;
  • True pay-for-performance technology for cleaning up sites; and
  • Installs in a few hours and is extremely easy to use.
