QM-ZviER-media is made by a unique physico-chemical combined process. Compared with the traditional iron powder, our micron iron powder has the characteristics of large specific surface area, low redox potential (ORP), high chemical activity and long-lasting effect. It can greatly improve the removal efficiency of chlorinated pollutants in soil and groundwater and greatly reduce the time of environmental remediation. It can be widely used in soil and groundwater remediation, industrial wastewater treatment and other application fields.

QM-ZviER products range in sizes from 5 μm to 2,000 μm and are suitable for any remedial treatment scenario involving reductive chemistry.

Abiotic β-Elimination
Designed to maximize β-elimination, QM-ZviER ZVI limits the production of harmful daughter products from hydrogenolysis. Hydrogenolysis is the sequential replacement of chloride ions with hydrogen, forming compounds like cis-DCE and VC, which are more toxic and can be rate-limiting during degradation. In β-elimination, two chlorine atoms are replaced with a triple bond between the carbons, forming an acetylene group. Chlorinated acetylenes will undergo rapid degradation with ZVI to form harmless ethene or ethane. All QM-ZviER products were designed to minimize the formation of toxic by-products.
