• Dislodges biofilm masses associated with iron oxidizing, sulfate-reducing and more prevalent slime forming bacteria, which are not removed by mineral acids alone
• Sequesters iron and inhibits corrosion on metal surfaces. Iron sequestering allows the chemical solution to remove heavy accumulation of iron compounds, often the cause of fouling water systems
• Protects all forms of metal in the system and will not attack plastic, neoprene or other synthetic materials, eliminating the need for acid inhibitors
• Provides passivation of metals when used with phosphoric acid
• NSF approved for cleaning potable water wells, pipelines and filter systems

Application

Nu-Well 310 bioacid dispersant is designed for mixing with acid solutions to improve the acid cleaning reaction. Standard dosage is 3 percent (1 to 2 percent for maintenance). Dosage of Nu-Well 310 bioacid dispersant can range from 0.5 to 5 percent (by weight) of treatment volume.

Optimal concentration depends on the type and severity of the deposit. It is recommended that well construction and performance history be submitted, along with water samples for lab analysis, to properly determine dosage on large municipal and industrial wells.

1. Surface prepare a solution of water, acid and Nu-Well 310 bioacid dispersant equal to approximately 40 percent of the total static volume into a vessel of appropriate size. First add water, then acid, then Nu-Well 310 biocacid dispersant. (Note: NEVER add water to acid! DO NOT mix Nu-Well 310 bioacid dispersant directly to commercial concentrations of liquid acid, as polymer destruction may occur.)
2. Place the surface-solution evenly across the intake zone, ensuring contact with affected areas at the recommended concentration. Agitate the cleaning solution to enhance the effectiveness of cleaning
3. The solution should remain in contact for 18 to 48 hours, depending on the nature of the deposit. Monitor the pH and keep it below 3.0 during treatment. If additional acid is needed (to lower pH), add an amount equal to approximately 20 percent of the initial amount of acid applied
4. Discharge the acid solution from the well, neutralize at the surface and dispose in accordance with local regulations
