The Cool-Ox® process is a hydrogen peroxide based technology designed to address a wide variety of remediation challenges presented by organic contaminants in various types of soils (especially clay) and groundwater. Although other hydrogen peroxide technologies may sound similar, only Cool-Ox® is based on a unique chemistry that truly delivers results.


What makes Cool-Ox® different? Unlike Fenton chemistry where liquid hydrogen peroxide is used as the source of the oxidizing radicals, the Cool-Ox® technology uses an aqueous suspension of solid peroxygen compounds. These compounds hydrolyze to generate hydrogen peroxide in the proximity of the contaminants. A key to the success of the technology is that the relative insolubility of these compounds allows the oxidizers to be produced over an extended period of time (up to three months). This long term production of oxidizer greatly enhances the probability of the oxidizing compounds contacting the contaminants as well as providing an ongoing source of molecular oxygen for the enhancement of aerobic microbial proliferation. 


The Cool-Ox®-R (Cool-Ox Reduction) process converts halogenated organic compounds directly to carbon dioxide and free chloride ion employing chemically reductive mechanisms. These reductive mechanisms, discovered by Sir Christopher Ingold and scientifically published in the late 1930s, are, nucleophilic substitution (SN1 & SN2) reactions, not chemical oxidation as is currently postulated by the establishment. During World War II, this mechanism was exploited to produce synthetic alcohol for the chemical industry and the Allied war effort. The process begins by breaking the olefinic double bond in an alkene with chlorine (Cl2) thus, converting the hydrocarbon to a chlorinated molecule. In a second reactor, the chloride ion is displaced by a (hydroxide ion (OH-) the nucleophile) thus, forming the alcohol. 

By adopting the mechanism to remediation of halide contaminates, DTI has successfully exploited the reactions as a most efficient remedial tool to destroy halogenated (chlorinated) contaminants. How? When chlorinated solvents are the target contaminants, the chloride ions are quickly replaced by hydroxide ions. These compounds (unstable in nature) are quickly converted to carbon dioxide. Some alcohols may be created but, these non-toxic compounds are quickly and easily mineralized by biological processes. No toxic intermediates (VC, DCE, DCA, etc.) are produced! And, if they are present, as a result of anaerobic dehalogenation, they are also quickly destroyed along with the parent compounds. Since these abiotic dehalogenation reactions are irreversible, no rebound is possible.



"I want to thank you for an excellent job on the RS project. The crew did excellent work each day and worked efficiently.  The equipment functions well and the operation of it is very efficient. James is an excellent crew chief and showed excellent leadership and excellent communication with us.  I appreciate his careful decisions and recommendations. There was good reactivity with the Cool-Ox® and after two years of groundwater monitoring, there has been no rebound."

URS and Dow

"URS’ Dow Business Unit was tasked with performing Dense Non-Aqueous Phase Liquid remediation at a former chemical plant.

The scope of work included collecting soil and groundwater samples, and completing pilot testing in advance of In-Situ Chemical Oxidation for mass reduction of the constituents of concern. The team used air-rotary drilling to clear underground obstructions, resulting in 2,072 injection points. This set the stage for ground treatment. Each injection point was then treated with Cool-Ox®, a calcium peroxide-based agent that was injected into the remediation target zone of subsurface soil. During these field activities, an unmarked underground storage tank was discovered and remediated. The Cool-Ox® treatment removed ~311,000 lbs. of COCs (67%).


The project team was acknowledged for working safely for 9,020 hours over five months—one of the coldest periods in Philadelphia’s history. Carl Coker, Dow Remediation Leader, formally recognized the exemplary safety effort: “Thank you all for your hard work and attention to safety during this major project at the Philadelphia plant. We were all committed to making this project a very safe and productive one [and] we succeeded because of the close cooperation of Deep Earth Technologies, Inc.
