� . r7 <br /> µy <br /> Re <br /> gen <br /> m <br /> CHEMICAL OXIDATION REDEFINED . . . <br /> RegenOx" is an advanced in situ chemical oxidation technology* designed to treat organic <br /> contaminants including high concentration source areas in the saturated and vadose zones <br /> PRODUCT FEATURES: <br /> ® Rapid and sustained oxidation of target compounds <br /> 40 Easily applied with readily available equipment <br /> • Destroys a broad range of contaminants <br /> ® More efficient than other solid oxidants <br /> 0 Enhances subsequent bioremediation 41 <br /> 41 Avoids detrimental impacts to groundwater aquifers <br /> RegenOx product application <br /> HOW IT WORKS: <br /> RegenOx maximizes in situ performance using a solid alkaline oxidant that employs a sodium percarbonate complex with <br /> a multi-part catalytic formula. The product is delivered as two parts that are combined and injected into the subsurface using <br /> common drilling or direct-push equipment. Once in the subsurface, the combined product produces an effective oxidation <br /> reaction comparable to that of Fenton's Reagent without a violent exothermic reaction. RegenOx safely, effectively and rapidly <br /> destroys a wide range of contaminants in both soil and groundwater(Table 1). <br /> ACHIEVES RAPID OXIDATION VIA A NUMBER OF MECHANISMS <br /> RegenOx directly oxidizes contaminants while its unique catalytic complex generates a suite of highly charged,oxidative free <br /> radicals that are responsible for the rapid destruction of contaminants.The mechanisms by which RegenOx operates are: <br /> 0 Surface- Mediated Oxidation: (see Figure 1 and description below) <br /> 0 Direct Oxidation: C,Ck+ 2 NazCO3 • 3 H2Oz + 2 H20 � 2CO2 +4 NaCl +4 H20 + 2 HzCO, <br /> 0 Free Radical Oxidation: <br /> —Perhydroxyl Radical (H02-) Figure 1.
