CleanER iZVI is a colloidal zero valent iron for chlorinated solvent remediation, but can also be applied to hazardous metals and herbicides/pesticides. It is manufactured exclusively for Cascade by Hoganas Environmental Solutions, the leading provider of engineered ZVI products across the world. CleanER iZVI primarily targets contaminants in transmissive zones down gradient of the source or in barrier applications, but can also be used in to treat less contaminated source areas to treat contaminants through via chemical reduction.
CleanER iZVI is a precisely blended liquid-suspension concentrate that is injected, via DPT or injection wells, to address chlorinated volatile organic compounds (CVOCs) and heavy metal contaminants, such as hexavalent chromium, arsenic, and selenium.
The unique formulation promotes broad dispersion in the subsurface at low and below fracture injection pressures, which optimizes distribution and contact. Through the process known as reductive dechlorination for solvents and chemical reduction for metals, the contaminants are degraded upon contact with the ZVI, and the byproducts are broken down into ethene and less hazardous forms of the target metals.
Can also treat less contaminated source areas.
