Product introduction :
Zero Valent Iron (ZVI) is a green & eco-friendly material, which can be used as a reducing agent in the environment remediation process. ZVI can remove various contaminants by chemical reduction, adsorption and co-precipitation. Furthermore, ZV could also be combined with bioremediation to significantly improve the remediation efficiency.
Our ZVI are made by a unique chemical method, with particle size range of 2 um - 250 um.
Compared with conventional ZVI powder,our ZVI powders have the characteristics of
• large specific surface area
• high reaction activity (>50 times higher than conventional ZVI)
• good adsorption capacity
• high purity (no harmful heavy metals)
• strong reduction property (ORP can reach-400mV)
• good longevity
which could significantly improve the removal efficiency of contaminants such as chlorinated solvent,hexavalent chromium in soil and groundwater,and shorten the environmental remediation time.
Ni/Fe Bimetal

Characteristic:
* Fe is the main component while Ni contained 5~25%,Customizable by application/site
* Higher reactivity compare with ZVI
* Uniform distributed of bimetallic elements with good stability
* Microcell electrolysis, could significantly improve the treatment efficiency of sewage
* Ni is recyclable
