Descale Heavy NuWell 130 Liquid Acid
- SKU:
- 10000317631
Descale Heavy is an aggressive acid for use in wells with heavy accumulation of calcium carbonate and
calcium sulfate scale. Descale Heavy is a NSF certified hydrochloric acid that effectively removes calcium
carbonate, calcium sulfate and other mineral deposits found in wells. When combined with Bio Dispersant
NW-310, Descale Heavy offers inhibition of the acid against metals in the well.
Application
When possible, obtain information on construction and performance history and submit water samples for
laboratory analysis before application to determine if dosage modifications are warranted.
1. Descale Heavy should be mixed into a tank containing a volume of water equal to 40% of the total treatment
volume. Use the dosage table to calculate the recommended dosage for general well cleaning. In wells with
longer screened intervals over 100 ft it is recommended to use 1.5 times the treatment volume to account for
the filter pack.
2. This mixture should be placed evenly across the well screens.
Placement methods should ensure contact with affected regions at
the desired concentration. Agitation of the acid into the plugged
area will greatly enhance the effectiveness of the cleaning.
3. The acid solution should remain in contact for a period of 12 to 48
hours, depending on the nature of the plugging.
4. Monitor the pH during the treatment, keep to below 3.0 for effective
cleaning. If pH level rises above 3.0, add additional acid solution of
approximately 20% of original volume. The amount of acid used will
depend on the degree of mineral scaling.
5. Discharge the acid solution from the well, neutralize on the
surface with Neutralizer NW-600 and dispose in accordance with
government regulations
