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 depositsfound in well, filter bed and water system equipment (iron, manganese, sulfates andcarbonates). A strong liquid acid for use in attacking stubborn mineral scale without risk to screensor casings, NW-120 is a chemically clean acid that won’t harm the well structure. Whencombined with the NW-310, NW-120 offers passivation of corrosion impacted areas, aidingolder well completions. Nu-Well 120 Liquid Acid1. Determine static height of well: SH = TD-SWL2. From table, determine standard dosage value by diameter3. Calculate volume of Nu-Well 120 liquid acid required:SH x Dosage = (gal./l.) Nu-Well 120 Physical properties, shipping and handlingAppearance: Clear colorless liquid, no odorDensity: 13.2 lbs./gal.Solubility in water: 100% in waterFreeze point: 26ºF (-3ºC)pH (as shipped): Aqueous approximately 1.00 to 2.00 – Nu-Well 120 liquid acid is a strong acid base and does not store well with strongalkaline materials or oxidizers– Dust respirators and goggles should be worn where possibility of dust or mistexists– Hazardous Class: 8, UNI 805, PGIII– Can be shipped ground by common carrier DOT Label Corrosive– Additional physical and handling data are available on the product SDS– Available in 15 and 55 gal. containers ExampleTreat 12 in. well, 180 ft. TD, SWL = 40 ft. Step 1Static height = (180 ft. – 40 ft.) = 140 ft. Step 2Dosage Value = 0.5 gal./ft. (12 in. well) Step 3Volume of Nu-Well 120 liquid acid =(140 ft. x 0.5 gal./ft.) = 70 gal.
