Cool-Ox - Environmental Site Remediation ISCO / ISCR Reagent

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.
