Remediation of groundwater and wastewater

with innovative colloidal particles

Who are we

ColFerroX GmbH is a startup based in the Rhein-Ruhr area, Germany. We develop and offer innovative solutions for groundwater, soil, and wastewater clean up, based on our established colloidal iron oxide particles and other more recent developments.
Our technologies have been verified for both wastewater and groundwater treatment at industrial scales. Together with University partners, ColFerroX GmbH develops innovative and field-approved solutions and offers them to the environmental remediation market. Our aim is to provide sustainable, environmental-friendly solutions for contaminated sites and industrial waste water.

Products

Iron-oxide colloidal particles

Our innovation is based on the unique properties of the ColFerroX iron oxide particles. In aqueous suspension, they behave perfectly colloidal with large surface area which make them perfect adsorbents for persistent pollutants such as heavy metals (As, Zn, Ni, Pd, Cd, Cr, Cu, …), cyanide, fluoride. The iron oxide can be added to any wastewater stream to adsorb all pollutants in one single setting, or be injected underground for in situ remediation of large plume.

Advantages of ColFerroX iron oxide

  • Non-toxic (Water Hazard Level Zero – WKG0)
  • Non-corrosive
  • Long-term (>3 months) colloidal stability
  • Very high sorption capacity
  • No H2S production

Silicon-based colloidal particles

Our patented silica-based particles and technology offers a one-for-all containment solution for isolation of any pollution in groundwater systems. Using this product, the source and plume zone can be contained very quickly and spreading of pollutants is minimized, ensuring high safety. The process works for any pollutant regardless of its type and is reversible, so no permanent changes to the environment are made.

Advantages of ColFerroX silica

  • Non-toxic, earth-abundant mineral
  • Non-corrosive
  • Long-term (> 12 months) colloidal stability
  • Reversible process
  • High stability against pressure and temperature
