C.E.R.E.S. Zero Valent Iron

Zero Valent Iron (ZVI)

Zero Valent Iron – High quality and purity micro scale iron powder and granules for water treatment or conditioning, permeable reactive barriers, and other soil and groundwater remediation applications.

Our Zero Valent Iron (ZVI) powder is manufactured either from 100% iron ore including sponge iron ore from Sweden. Our iron content is available at up to 99.5% purity. Our ZVI is produced with high quality proprietary grinding and pulverizing technology to produce many thousands of tons per year of ZVI powder with no appreciable surface oxides.

Zero Valent Iron (ZVI)

Benefits Include

  • Proven remediation technology since the 1970’s
  • ​Applicable in soil piles and in-situ applications for groundwater treatment
  • Economical solution for chlorinated solvent and hexavalent chromium remediation applications
  • ​Easily applied by soil mixing or injection
  • Can be injected with low pressure (10 micron or smaller ZVI)
  • Can combine with MTS for mixed contaminant plumes of heavy metals and organics.

Proven Field Applications

  • Permeable reactive barriers (PRBs) and Funnel & Gate Design
  • Trenching and aggregate size ZVI particles for PRB design
  • Deep Soil Mixing generally uses aggregate scale size
  • Source area grid injection or soil mixing
  • Direct push injection (generally <200 micron) or permanent injection wells (<10micron only)
  • Low pressure injection (10 micron or smaller ZVI),
  • Moderate pressure injection (10-44 micron ZVI)
  • Hydraulic fracking and higher pressure injection (greater than 44 micron ZVI)
