Application
Laboratory testing and field trials demonstrate that successful well chlorination is achieved with a chlorine concentration of 200 ppm. The following procedures are recommended for using Chlor-Boost chlorine enhancer with chlorine concentrations of 200 ppm.
1. Determine the static volume, the amount of Chlor-Boost and the amount of chlorine product necessary to treat the well. (Consideration should be given to increasing this volume by two to four times to allow sufficient disinfectant solution to reach all areas of the well and borehole that can harbor coliform bacteria or other contaminating organisms.)
2. In a tank on the surface, add the amount of Chlor-Boost to water as estimated from dosage guide. Mix the solution and measure the pH. The pH of the solution should be between 4.5 and 5 before adding the hypochlorite. All mixing should be done in a well-ventilated area. Caution: When chlorine is placed in an acid pH of 5.0 or lower, chlorine gas can be released. When the hypochlorite solution or powder is added, the pH will rise immediately, preventing any further 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 solution throughout the water column
4. Agitate or surge the mixture to ensure good coverage. Let the solution stand in the well for 5 to 12 hours. Additional agitation before removal is beneficial. Chlor-Boost is buffered to hold the pH at the optimal level. However, if additional Chlor Boost is required, blend in a volume equal to 25 percent of the original mixed volume and add carefully so that the pH does not drop below 5.0, resulting in release of chlorine gas.
5. Pump the solution to the surface, neutralize using Chlor-Out NW-500, and discharge in accordance with local rules and regulations.
