t � <br /> REGENESIS <br /> 8) In some cases, introduction of a large column of air prior to RegenOxTm application <br /> may be problematic because the air can block water flow to the treatment area. This is <br /> particularly the case in deep injections (>50 ft) with large diameter rods (>1.5-inch <br /> O.D.). To prevent the injection of air into the aquifer during RegenOxTm application, <br /> as well as to prevent problems associated with heaving sands, fill the drive rods with <br /> water, or the RegenOxTM mixture prior dropping the expendable tip or exposing the <br /> injection tool. <br /> 9) The RegenOxTM percent of the oxidizer in solution should range between 3%to 5%. <br /> Although solutions up to 8%may be used, this will likely increase the difficulty of <br /> injection due to reactivity. Solutions with greater than 8% oxidizer in solution will <br /> result in excess reaction and flocculation prior to injection and are not typically <br /> recommended <br /> Measure the appropriate quantity of RegenOxTM Oxidizer for one to four vertical foot <br /> of injection into a 55 gallon drum or mixing tank. The volume of water per injection <br /> location can be calculated from the following formula: <br /> RegenOx Oxidizer lbs/foot <br /> g [1—(%RegenOx_Oxidizer solids)] <br /> (8.34 lbs/gal waterX%RegenOx_Oxidizer solids) <br /> Tighter formations (clays and silts), and even some fine sand formations will likely <br /> require higher oxidant percentages since less volume can be injected per location. <br /> The following are guides to various RegenoXTM mixing ratios based on the above <br /> equation. <br /> • to make a roughly 3% oxidant solution for every 10 lbs of oxidant and 10 lbs <br /> of activator(20 lbs total RegenOxTM), use 38 gallons of water. <br /> • to make a roughly 4% oxidant solution for every 10 lbs of oxidant and 10 lbs <br /> of activator(20 lbs total RegenOxTM), use 28 gallons of water. <br /> • to make a roughly 5% oxidant solution for every 10 lbs of oxidant and 10 lbs <br /> of activator(20 lbs total RegenOxTM), use 22 gallons of water. �. <br /> Zo <br /> 10) Pour the pre-measured quantity of RegenOxTM Oxidizer into the pre-measured <br /> volume of water to make the desired target% oxidant in solution. NOTE: always <br /> pour the Oxidizer into water, do not pour water into the Oxidizer. Mix the water <br /> and oxidant with a power drill and paint stirrer or other mechanical mixing device <br /> to ensure that the Oxidizer has dissolved in the water. <br /> RegenOx Direct-Push Step-by-Step I www.regenesis.com 1949-366-8000 <br />
