As an eco-friendly and efficient reducing material, zero valent iron powder (ZVI) is widely applied in modern environmental remediation projects, covering contaminated soil restoration, groundwater purification and industrial wastewater disposal. Sagwell provides a full range of professional environmental remediation iron powder products, including ultra-fine iron powder, standard zero valent iron powder, spherical porous iron powder and Fe-Ni bimetallic composite powder. These diversified products can adapt to various site conditions and construction techniques to meet personalized pollution treatment demands.
Distinct from traditional remediation materials, high-quality ZVI powder eliminates pollutants through three core mechanisms: chemical reduction, physical adsorption and co-precipitation. It can also combine with biological remediation technologies to greatly enhance overall treatment efficiency.
Adopting advanced chemical synthesis processes, our zero valent iron powder features a particle size range of 2μm to 250μm. Boasting a larger specific surface area, its reaction activity is 50 times higher than conventional ZVI products. With pure composition free of harmful heavy metals, it effectively removes chlorinated solvents, hexavalent chromium and other stubborn pollutants, greatly shortening the entire remediation cycle.
The product lineup includes multiple customized models for different scenarios. The UIF ultra-fine iron powder (0.5-5μm) has served the international environmental remediation market and matched EZVI emulsified ZVI technology with stable performance since 2004.
The EG series spherical porous iron powder (50-250μm) has high porosity and permeability with low consumption, ideal for soil mixing, in-situ injection and PRB systems. Independently developed in 2019, the Fe-Ni bimetallic powder is specialized for complex printing, chemical and electroplating wastewater. Custom UH, HH and other tailored ZVI products are also available for diverse construction needs.
With mature production technology and long-term overseas project experience, Sagwell’s high-performance zero valent iron powder and environmental remediation iron powder deliver stable, safe and cost-effective material support for global environmental remediation engineering.
