Application Descale Plus is used in well cleaning operations as a granular product mixed in a tank with water to dissolved and then pumped into the well as a liquid. 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 Plus should be mixed into a tank of water equal to 40% of the total treatment volume. The attached table provides the recommended dosage for general well cleaning. In wells with over 100 ft. of screened intervals it is recommended to use 1.5 times the treatment volume to account for the filter pack.

2. The 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. Product has limited use where heavy deposits of gypsum are suspected (add Bio Dispersant NW-310 in this situation).

4. Monitor pH often during treatment and keep below 3.0 for effective cleaning. If pH rises above 3.0 add additional acid solution of approximately 20% of original volume. The amount of acid consumed 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 the appropriate regulations.
