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

Zero Valent Iron

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

Our Zero Valent Iron powder is manufactured either from 100% sponge iron ore or 100% recycled virgin iron material from trusted OEM manufacturers. Our iron content is available at purities of up to 99.5%. We use high quality raw materials and proprietary grinding and pulverizing technology to produce many thousands of tons per year of ZVI powder with no appreciable surface oxides.

Zero Valent Iron
