From Redox Tech Solutions
Redox Tech also offers ABC+, which includes the original ABC formula as well as ZVI. With the additional ZVI, ABC+ has a much quicker effect on contamination, and additional hydrogen from ZVI also provides nutrients to bacteria in the groundwater.
Originally, ABC+ was created to reduce source area concentrations, due to the rapid creation of hydrogen from ZVI corrosion in the treatment process, but the use of the solution has expanded to include in reactive barriers, metals and nitroaromatic treatments.
Another advantage of ABC and ABC+ is its ability to be used in low-permeability environments, including silt and clay.
