Modulated TersOx™ Liquid

In Situ Chemical Oxidation (ISCO) - Catalyzed Hydrogen Peroxide (CHP)

Looking for a slow release ISCO option?  Modulated TersOx™ Liquid offers potency, stability and persistence of biological polishing. TersOx™ Modulator will slowly and steadily activate TersOx™ Liquid, generate hydroxyl radicals that destroy contaminants.  This powerful and non-selective preliminary reactions can oxidize a wide variety of organic contaminants into non-regulated compounds, yet it is extremely stable to be blended as one product for subsurface injection, above ground for safety, for long-lasting effects below ground, and to allow contact where needed.  

The performance of standard oxygen releasing TersOx™ and TersOx™ Nutrients following a Modulated TersOx™ Liquid event significantly improves, allowing overall project goal to be met sooner and permanently, while keeping costs low. Up-to-date research shows this one-two punch approach give is much more efficient: by targeting just sufficient mass discharge drops, the sum of both steps removes more contaminant mass at less cost than ISCO or Bio as stand-alone approaches.

In Short: TersOx™ family of products are a combination of hydroxyl free radicals, slowly released oxygen and nutrients specially formulated to give you more bang for your buck.


Our exothermic controlled in situ chemical oxidation technology minimizes the amount of heat and pressure that are generated, and it is not pH sensitive like conventional Fenton reaction-based systems.  Advantages include:

  • Slower caloric release when compared to traditional Fenton's reagent (suppresses the exotherm and stays in first order kinetics)
  • Excess pressure buildup is controlled
  • Excess temperature buildup is controlled
  • Formulated for: above-ground blending, long-lasting effects below ground, and to allow contact where needed
  • Chemical daylighting is controlled
  • Does not discolor nearby receptors such as water recovery wells or nearby surface water bodies as is the case with permanganates
  • Does not form insoluble byproducts that could clog the aquifer
  • Compatible with bioremediation
  • Ideal reagent for in situ surfactant and chemical oxidant flushing for complete remediation of contaminants (Tersus assigned U.S. Patent Nos. 6,913,419 B2; 7,021,863 B2; 7,364,386 B2; 7,708,496 B2; and 7,677,836 B2)
  • Permanent, minimizes rebound
