Nu-Well 410 Chlorine Enhancer

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 Nu-Well 410 chlorine enhancer with chlorine concentrations of 200 ppm.

Insights

  1. Determine the static volume, the amount of Nu-Well 410 chlorine enhancer and the amount of chlorine product necessary to treat the well according (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 Nu-Well 410 chlorine enhancer 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. Nu-Well 410 chlorine enhancer is buffered to hold the pH at the optimal level. However, if additional Nu-Well 410 chlorine enhancer 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 Nu-Well 500 Chlorout, and discharge in accordance with local rules and regulations.

Nu-Well 140 Dosage Guide

  1. Determine static height (TD - SWL).
  2. Multiply amount of chlorine enhancer from table by static height
  3. Determine amount of hypochlorite product from table 
  4. Surface batch = water + Nu-Well 410 chlorine enhancer + hypochlorite


Example

Disinfect a 16 in. well, TD = 300 ft, 

SWL = 50 ft. with calcium hypochlorite 65 percent active

Step 1 Static height = (300 ft. - 50 ft.) = 250 ft.

Step 2 Amount enhancer = 250 ft. x 0.042 qt./ft. = 11 qt.

Step 3 Amount hypochlorite = 250 ft. x 0.027 lb./ft. = 6.8 lbs.     

Step 4 Batch: 250 ft. x 10.47 gal./ft.= 2,618 gal. water (2,618 gal. + 11 qt. + 6.8 lbs.)

Note: Amounts based on application of 200 ppm chlorine concentration into well water with alkalinity of 100 ppm.

If well water alkalinity or the recommended chlorine dosage level is greater than the standard values in the above table, adjust the amount of chlorine enhancer and the amount
of hypochlorite concentrations as shown below

Nu-Well 410 Chlorine Enhancer

Hypochlorite

Amount above x (Alk/100)

Amount above x (recommended concentration/200)

Tip: Optimal results are obtained when the surface solution is two to four times the well volume, providing sufficient hypochlorite ions to disperse into the gravel pack and immediate surrounding formation where coliform organisms exist. For large wells, this may not be practical and multiple batches, with proportions of chemistry, may be required to achieve desired results
