Effective control of pollutant plumes

Intrasorp® is the suspension that contains our specialized activated carbon colloids. In 2004, it was developed and patented at one of Europe’s leading environmental research centers – UFZ Leipzig – and is exclusively distributed by Intrapore. With Intrasorp®, we can create in situ adsorption barriers to quickly prevent the spreading of plumes or limit the leaching of source zones with respect to a wide variety of organic contaminants.

The Intrasorp® suspension shows a superior subsurface mobility during injection, a irreversible deposition at the target zone and a vast adsorption capacity.

It has been proven successfully in multiple remediation projects at multiple sites, with injection permissions by local water authorities.

Field-proven: Successful full-scale applications

  • Adsorption of BTEX, PAH, mineral oil hydrocarbons for the long-term immobilization of contaminants in groundwater plumes or source zones.
  • Effective adsorption of a wide variety of further organic contaminants.
  • Can be injected into the aquifers as colloidally stabilized suspension via direct push or via existing measuring wells.
  • Irreversible deposition after injection, no uncontrolled mobility of “renegade” AC colloids.
  • Immediate cutoff of contamination plumes.
  • Sustained lifetimes of the in situ adsorption barrier
  • Field-proven full-scale remediation applications.
  • Superior, drinking-water quality – Made in Germany and scientifically validated.
  • Can be boosted by our patented Intrablue® additive: colloidal iron oxides will be mixed into the Intrasorp® suspension. The iron oxide colloids serve as electron acceptors for anaerobic microorganisms, greatly enhancing the microbial degradation of contaminants under anoxic conditions.

    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.
