SAGWELL has more than 20 years experience in micro & nano metal powder materials, our core business is the supply of micro & nano iron powder, copper powder and pre-alloyed powder. SAGWELL`s metal powder can be widely used in powder metallurgy, chemistry, diamond tools, environmental remediation, electronic components and other industries. For Groundwater & Soil Remediation (ZVI), we supply 4 materials, like superfine iron powder, zero valent iron, bimetal material and spherical parous iron powder. Our superfine iron powders have been introduced into America since 2004, we have become a major supplier of m-ZVI products for the preparation of emulsified zero valent iron (EZVI).
Our micron iron powder (m-ZVI) 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 aging property. It can significantly 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 and industrial wastewater treatment and other fields.
Our powders have been introduced into America since 2004, we have become a major supplier of m-ZVI products for the preparation of emulsified zero valent iron (EZVI) (for the remediation of soil and groundwater chlorinated pollutants).
• Approximately spherical particles
• 0.5~10μm particles, precise control of particle size distribution
• High specific surface area, strong reducibility, high chemical activity, high adsorption performance
• Significantly reduce the time required for the remediation of pollution
• Environmentally friendly
In recent years, zero valent iron (ZVI) has been widely used in soil, groundwater and industrial wastewater treatment. Our zero valent iron (ZVI) is made by a unique physico chemical combined process with particle size up to 10~100μm.
Compared with the traditional zero valent iron, our zero valent iron has the characteristics of high purity (not containing harmful heavy metals), strong reducibility (low redox potential ORP) and long aging property.It can significantly improve the removal efficiency of chlorinated solvents in soil and groundwater, six valent chromium and so on, and greatly reduce the time of environmental remediation.
• 10~100μm fine particles, can be customized according to the application direction / site.
• Large specific surface area, can maintain strong reduction ability for a long time.
• High chemical activity and good adsorption performance.
• The duration of the effect is long and the number of injections is reduced.
• Significantly reduce the time required for the remediation of pollution.
• Environmentally friendly
Through the unique preparation process, we have developed a special wastewater treatment material, that is, bimetal material, which can be used to deal with printing and dyeing wastewater, chemical wastewater, electroplating wastewater and so on.
We provide a variety of bimetal materials with different components. Here we introduce one of the bimetal materials, Ni/Fe bimetal material.
The bimetallic elements in the material are evenly distributed and have good stability. The formation of micro batteries between Fe and Ni promotes the rapid degradation of pollutants, and has higher catalytic activity, which can greatly improve the efficiency of sewage treatment. Ni in the material is used as a catalyst and can be recovered at the end of the wastewater treatment process
If you want to know more information about bimetal materials, please feel free to contact us.
According to the market demand, through the unique preparation process, we developed a new type of spherical porous iron powder (particle size 10~3000μm), which has good service life, suitable for long-term repair projects, at the same time reducing the number of injection and reducing cost; high porosity, large specific surface area, high reactive activity, and Strong reducibility (low ORP) ) and other characteristics can significantly improve the treatment efficiency of pollutants.
High permeability can not only be used in conventional soil and groundwater pollution repair process (in situ injection), but also used as active filler in the permeable reaction wall (PRB); higher adsorption capacity makes it have a wide range of applications. According to customer needs, it can be customized according to the application direction / venue.
