Descale Safe Nu-Well 120 Liquid Acid is the optimal basic ingredient for many cleaning applications.

This liquid food grade phosphoric mineral acid effectively removes common mineral deposits
found in well, filter bed and water system equipment (iron, manganese, sulfates and
carbonates).

A strong liquid acid for use in attacking stubborn mineral scale without risk to screens
or casings, NW-120 is a chemically clean acid that won’t harm the well structure. When
combined with the NW-310, NW-120 offers passivation of corrosion impacted areas, aiding
older well completions.

Nu-Well 120 Liquid Acid
1. Determine static height of well: SH = TD-SWL
2. From table, determine standard dosage value by diameter
3. Calculate volume of Nu-Well 120 liquid acid required:
SH x Dosage = (gal./l.) Nu-Well 120

Example
Treat 12 in. well, 180 ft. TD, SWL = 40 ft.

Step 1
Static height = (180 ft. – 40 ft.) = 140 ft.

Step 2
Dosage Value = 0.5 gal./ft. (12 in. well)

Step 3
Volume of Nu-Well 120 liquid acid =
(140 ft. x 0.5 gal./ft.) = 70 gal.
