ZVI MicroMetal Suspension

Biochemical Remediation Fast & Easy!

In Situ Chemical Reduction (ISCR) is an innovative environmental remediation technique used for soil and/or groundwater remediation to reduce the concentrations of targeted environmental contaminants to acceptable levels.  ISCR combines biological processes and zero valent iron (ZVI) particle-driven abiotic pathways to chemically reduce persistent organic compounds such as chlorinated solvents, pesticides and energetic compounds into harmless end products. The incorporation of ZVI enhances remediation by enabling various chemical reduction pathways and limits the formation of undesirable chlorinated ethene breakdown products such as Cis-DCE and vinyl chloride.

ZVI MicroMetal Suspension is engineered to accomplish the rapid and sustained degradation of chlorinated hydrocarbons and other toxic groundwater contaminants. With 40% two to three micrometers (2-3 μm) ZVI in a water-based system with glycerol and biodegradable food grade biopolymer, no other ZVI product provides the unique combination of small particle size, ease of use, and reactivity with many common groundwater contaminants.

Product Overview

ZVI MicroMetal Suspension contains reactive metal particles suspended in an organic carrier. The average particle size is approximately 2-3 μm. This is the optimum size for in situ remediation and provides a unique combination of rapid reactivity and mobility through groundwater.

Tech Brief

Suggested Application Instructions

Easy to Use

ZVI MicroMetal Suspension (~3,000 cP; 14 lbs./gallon) is very easy to mix and inject into contaminated groundwater. The fluid is pumped or poured into mixing tanks containing water and optionally, other remediation amendments. The resulting aqueous suspension is then pumped directly into the contaminated groundwater at pressures that are often below 20 psi.

No other zero valent metal products can be injected with such a diverse set of equipment including pneumatic diaphragm pumps, progressing cavity pumps, and centrifugal pumps. A unique feature ZVI MicroMetal Suspension is the ability to be injected through horizontal and vertical screened wells as well as sampler screens via DPT.
