DescriptionUsed with hypochlorite to increase effectiveness of chlorinationMaintains pH in well at 6.5 during chlorination, increasing hypochlorus acidIncreases bacteriological activity by more than 100 times that of hypochloriteContains a penetrant to allow deeper and more complete disinfectionControls calcium in hard water to increase the effectiveness of calcium hypochloriteNSF certified for potable water well use ApplicationNu-Well 410 is a unique chemistry that improves the biocidal capabilities ofchlorine while increasing the treatment area and providing secondary cleaning– significantly enhancing traditional chlorination efforts. Nu-Well 410 is appliedbased on the water chemistry and chlorine concentrations, maximizing chlorineeffectiveness, specific to your well.Laboratory testing and field trials demonstrate that successful well chlorination is achieved with a chlorine concentration of200 ppm. The following procedures are recommended for using Nu-Well 410 chlorine enhancer with chlorine concentrations of 200 ppm. 1. Determine the static volume, the amount of Nu-Well 410 chlorine enhancer and the amount of chlorine product necessaryto treat the well according (Consideration should be given to increasing this volume by two to four times to allow sufficientdisinfectant solution to reach all areas of the well and borehole that can harbor coliform bacteria or other contaminatingorganisms.)2. In a tank on the surface, add the amount of Nu-Well 410 chlorine enhancer to water as estimated from dosage guide. Mixthe solution; and measure the pH. The pH of the solution should be between 4.5 and 5 before adding the hypochlorite. Allmixing should be done in a well-ventilated area. Caution: When chlorine is placed in an acid pH of 5.0 or lower, chlorinegas can be released. When the hypochlorite solution or powder is added, the pH will rise immediately, preventing anyfurther chlorine release, but you should add the hypochlorite quickly and move away until the pH rises.3. Place the chlorine solution in the well, evenly washing down the upper levels of the well before you place the solutionthroughout the water column4. Agitate or surge the mixture to ensure good coverage. Let the solution stand in the well for 5 to 12 hours. Additionalagitation before removal is beneficial.Nu-Well 410 chlorine enhancer is buffered to hold the pH at the optimal level. However, if additional Nu-Well 410 chlorineenhancer is required, blend in a volume equal to 25 percent of the original mixed volume and add carefully so that thepH does not drop below 5.0, resulting in release of chlorine gas.5. Pump the solution to the surface, neutralize using Nu-Well 500 Chlorout, and discharge in accordance with local rules andregulations.
