Effective control of pollutant plumes

Intrasorp® is our colloidal liquid activated carbon suspension. It was developed and patented in 2004 at one of Europe’s leading environmental research centres (Helmholtz UFZ Leipzig) and is applied exclusively by Intrapore on a field scale and distributed throughout Europe. With Intrasorp® we can create sorption barriers for almost all organic pollutants in order to prevent the spread of pollutant plumes or permanently immobilise source zones.

The Intrasorp® suspension is characterised by outstanding mobility in the subsoil during injection, permanent deposition within the target zone and a high adsorption capacity for an wide range of organic pollutants.

The product has already proven itself at many sites: The water authorities’ injection permits have been granted without any problems, and the application itself can be carried out reliably even under complex conditions (with ongoing operations on the site, dense pipe networks, restricted working area, etc.).

Field-proven: Successful full-scale applications

  • Rapid adsorption of BTEX, PAHs and mineral oil hydrocarbons (including halogenated ones) for long-term immobilisation of pollutants in groundwater plumes or source areas
  • Effective adsorption of a wide range of other organic contaminants as well
  • Can be used as a colloidally stabilised suspension in situ, via direct push or via injection into
    existing wells or borehole into the aquifer
  • After injection, permanent deposition of the activated carbon particles on the soil matrix occurs, there is no uncontrolled “renegade” mobility
  • Immediate cutting off of the contaminant plume
  • Long-lasting effectiveness of the in situ adsorption barrier,  with robust planning, exact dosing and proper application: usually in the range of several decades
  • Field-proven remediation applications in large-scale field applications
  • Outstanding product quality – approved for use even in drinking water, made in Germany and scientifically validated
  • Can be boosted by our patented Aquaferrox® additive: Iron oxides serve as an electron acceptor for anaerobic microorganisms and thus improve the degradation of pollutants.

    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 degradation of halogenated pollutants

    CarboIron® is the sustainable and exceptionally effective alternative to conventional iron – and this applies with equal regard to mobility during injection, sustainable reactivity and effectiveness. Organic halogen pollutants such as PCE and TCE are effectively and permanently immobilised, being fully degraded into ethene and ethane.

    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.
