REGENESIS Regen • <br /> CHEMICAL OXIDATION REDEFINED <br /> RegenOxTM In Situ Chemical Oxidation Application Instructions <br /> Using Direct-Push Injection (Step-by-Step Procedures) <br /> RegenOxTM is the new generation of chemical oxidation. RegenOxTM is a proprietary <br /> (patent-applied-for) in situ chemical oxidation process using a solid oxidant complex <br /> (sodium percarbonate/catalytic formulation) and an activator complex(a composition of <br /> ferrous salt embedded in a micro-scale catalyst gel). RegenOxTM with its catalytic system <br /> has very high activity, capable of treating a very broad range of soil and groundwater <br /> contaminants including both petroleum hydrocarbons and chlorinated solvents. <br /> Instructions <br /> 1) Prior to the installation of RegenOxTM, any surface or overhead impediments should <br /> be identified as well as the location of all underground structures. Underground <br /> structures include but are not limited to utility lines; tanks; distribution piping; <br /> sewers; drains; and landscape irrigation systems. The planned installation locations <br /> should be adjusted to account for all impediments and obstacles. These <br /> considerations should be part of the SSHP or HASP. <br /> 2) Pre-mark the installation locations, noting any points that may have different vertical <br /> application requirements or total depth. <br /> 3) Set up the direct push unit over each point and follow the manufacturer standard <br /> operating procedures (SOP) for the direct push equipment. Care should be taken to <br /> assure that probe holes remain in the vertical. <br /> 4) For most applications, Regenesis suggests using 1.5-inch O.D./0.625-inch I.D drive <br /> rods. However, some applications may require the use of 2.125-inch O.D./1.5-inch <br /> I.D. or larger drive rods. <br /> 5) Advance drive rods through the surface pavement, as necessary, following SOP. <br /> 6) Push the drive rod assembly with an expendable tip to the desired maximum depth. <br /> Regenesis suggests pre-counting the number of drive rods needed to reach depth prior <br /> to starting injection activities. <br /> 7) After the drive rods have been pushed to the desired depth,the rod assembly should <br /> be withdrawn three to six inches. Then the expendable tip can be dropped from the <br /> drive rods, following SOP. If an injection tool was used instead of an expendable tip, <br /> the application of material can take place without any preliminary withdrawal of the <br /> rods. <br /> RegenOx Direct-Push Step-by-Step I www.regenesis.com 1949-366-8000 <br />
