Remediation of groundwater and wastewater
with innovative ironoxide particles
The technology
Our innovation is based on the unique properties of the ColFerroX iron oxide nanoparticles. In aqueous suspension, they behave perfectly colloidal and can thus be injected into aquifers like a liquid over a radius of several meters.
Due to the subsequent contact with the groundwater and the sediment, the particles precipitate within a few days. The surface of the sediment is thus coated with iron oxides and the particles remain in the aquifer; they form a permeable barrier which adsorbs pollutant such as heavy metals (As, Zn, Ni, Pd, Cd, Cr, Cu, …) or cyanide.
