About Carbo Iron®

Carbo-lron® is a patented, micron-sized composite material composed of zerovalent iron and activated carbon. Pollutants are quickly adsorbed by the activated carbon, thereby withdrawn from the groundwater flow and at the same time permanently attached to the reactive zero-valent iron cores. Carbo-lron® is non-pyrophoric during onsite handling, shows outstanding migration distances through porous media during its injection, also adsorbs free pollutant phase, and facilitates a complete and VC-free dehalogenation.

This superior material, developed by the Helmholtz Center for Environmental Research – UFZ in Leipzig, opens up completely new, highly effective ways for CHC source remediation and the establishment of reactive zones within the groundwater flow.

For reductive in situ dehalgenation of PCE/TCE

  • Microscale, zero-valued iron, embedded in an activated carbon composite structure
  • Injected as liquid suspension, mobility controlled by coatings, up to 20 m
  • Complete, abiotic, VC-free reductive dehalogenation
  • Works also for some pesticides and explosives  residue components.
  • Penetrates the pollutant phase, adsorbs the pollutant.
  • Non-pyrophoric during on-site handling.
  • Corrosion-stabilized, effective over the long term.
  • Scientifically validated.
  • Field-tested and approved under water regulations

    Rapid and sustained in situ immobilzation of organic contaminants

    On a sustainable basis: Intrasorp® can be precisely adapted to the different adsorption behaviour of the respective pollutants. MOHCs, BTEX, PAH and many other organic pollutants can thus be quickly and permanently immobilised and removed from the downstream groundwater flow.

    Unique and patented in situ immobilization of heavy metals

    Effective remediation of groundwater: Aquaferrox® enables the permanent binding of heavy metals and metalloids in groundwater. The dissolved ions are safely immobilised by adsorption. Aquaferrox® is characterised by high adsorption capacity, thermodynamic stability and ecotoxicological safety. Easy to apply with standard direct-push systems.

    For the treatment of persistent pollutants

    With TrapOx®, combined adsorption and reaction zones can be created in which especially persistent pollutants can be enriched and degraded on a successive basis.

    The preferred areas of application include effluent plumes of persistent organic pollutants such as phenols, large PAH molecules, halogenated hydrocarbons such as dichloromethane and chlorobenzene, or MTBE.

    Rapid and sustained in situ PFAS immobilization

    PFAS remediation places the highest demands on the in situ materials. With Intraplex® activated carbon, Intrapore offers a colloidally stabilized suspension that is injected directly into the contaminated aquifer, where it rapidly and permanently immobilizes PFAS.
