Groundwater Remediation

Highly efficient in removal of

• Inorganic compounds like Arsenic, Barium, Chromium, Selenium, Uranium, Copper, Lead, Cadmium, Mercury, Nickel (and many other heavy metals), sulphates, nitrates,perchlorates, etc.
• Organic compounds like polychlorinated methanes, ethanes, ethenes, benzenes, etc

Properties of fe⁰ nanoparticles

• High redox potential (electron donor)
• High surface area (20-25 m²/g)
• Narrow particle size distribution (average of 50 nm) allowing the particles to migrate in groundwater conditions
• Pyrophoric or air-stable character (powder or aqueous dispersion)
• Magnetically separable
• High-reactivity and long-term performance
• Possibility to combine various properties in composite materials
• Ideal for remediation of large areas or for construction of permeable reactive barriers
• Environmentally friendly material
• Low cost comparing to conventional technologies

NANOFER 25P

• Fe⁰ nanoparticles (powder) without surface modification
• Highly reactive and pyrophoric Fe⁰ nanoparticles

NANOFER 25S

• Aqueous dispersion of Fe⁰ nanoparticles modified by biodegradable organic stabilizer
• Highly reactive with large scale of pollutants
• Excellent migration properties

NANOFER STAR

• Surface-stabilized Fe⁰ nanoparticles (powder)
• Safe storage, transport, handling and applications compared to non-stabilized Fe⁰ nanoparticles
• When activated, the Fe⁰ nanoparticles are highly reactive with reducible pollutants
• Possibility to combine with biodegradable organic stabilizer for better migration performance

Fe⁰-based composites

• Micro-Fe⁰ & nano-Fe⁰ composite material combining long-term reactivity of microparticles with rapid effect of nanoparticles
• Nano-Fe⁰ & carbon composite material combining reductive/magnetic properties of Fe⁰ nanoparticles with sorption properties of carbon (active carbon, carbon black, nanotubes, biochar etc.)
