Chemical Oxidation


PersulfOx is an advanced in situ chemical oxidation (ISCO) reagent that destroys organic contaminants found in groundwater and soil through abiotic chemical oxidation reactions. It is an all-in-one product with a built-in catalyst which activates the sodium persulfate component and generates contaminant-destroying free radicals without the costly and potentially hazardous addition of a separate activator. The patented catalyst enhances the oxidative destruction of both petroleum hydrocarbons and chlorinated contaminants in the subsurface.


RegenOx in situ chemical oxidation (ISCO) directly oxidizes contaminants while its unique catalytic component generates a range of highly oxidizing free radicals that rapidly and effectively destroy a range of target contaminants including both petroleum hydrocarbons and chlorinated compounds. RegenOx is an injectable, two-part ISCO reagent that combines a solid sodium percarbonate based alkaline oxidant (Part A), with a liquid mixture of sodium silicates, silica gel and ferrous sulfate (Part B), resulting in a powerful contaminant destroying technology.


Pump and treat. Pump and treat technology involves the removal of groundwater from the aquifer and treatment of the various pollutants. Treatment can consist of a variety of technologies, including bioreactors, filtration, and oxidation systems.

Hydrogen peroxide is used in a number of pump and treat systems, including iron removal systems and Advanced Oxidation Processes (AOPs), such as UV/ H2O2, and 03 /H2O2 as well as bioreactor systems.

Peroxidation. Peroxidation technology is the direct oxidation of organic contaminants in the soil. This treatment occurs either in-situ or ex-situ, with peroxide alone or catalyzed with Fenton’s Reagent.

Biological treatment. Biological treatment can take a number of different forms, including landfarming, pump and treat bioreactor systems and in-situ bioremediation.

Landfarming. Landfarming consists of plowing the appropriate microorganisms, nutrients and sometimes additional wastes into the soil to form a compost. This mixture provides the appropriate environment for the microorganisms to degrade the contaminants.

Bioreactor systems. Bioreactor systems, used in pump and treat systems, represent an efficient and inexpensive approach for treating halogenated aliphatics.

In situ bioremediation. In nature, biodegradation occurs slowly because of the low population of microorganisms with degradation ability. Degradation is also hindered because of environmental conditions, such as nutrient levels. Stimulating the environment will speed up this process.


Potassium Persulphate is a very strong oxidant with a wide range of applications. Prominent among these is its use in the oxidation of organic contaminants especially hydrocarbons in the environment.
