Main Applications

  • Suitable for BTEX, PAHs and mineral oil hydrocarbon contaminations
  • Direct chemical oxidation of contaminated source zones
  • Long lasting bioremediation of BTEX and PAHs plumes
  • Patented, field-proven, and ecosafe application

Target contaminants

Organic hydrocarbons such as BTEX or PAHs are common pollutants found in groundwater resulting from petroleum processing, refining, storage, and other industrial activities. Typically, these carcinogenic compounds accumulate in low-permeability sediments and sustain contaminant plumes extending for hundreds of meters along the groundwater flow path.

 

Benefits

intrablue® is an innovative and field-proven nanomaterial to effectively remediate BTEX or PAHs source areas and groundwater contaminant plumes. Our nanomaterial deposits in the highly contaminated areas and then acts as a reagent for the oxidation of organic pollutants. intrablue® is also employed for the treatment of persistent low-concentration plumes.

For this purpose, reactive biobarriers are created in the aquifer to stimulate bioremediation, which in turn enhance natural attenuation processes.

intrablue®

For the oxidative decomposition of mineral oil pollutants

The typical contamination profiles in the petrochemical, oil and gas industries mostly consist of BTEX, PAH, MOH and MTBE – as a highly concentrated source contamination with free NAPL or highly mobile contaminant plume. With intrablue® we are able to adapt our remediation strategy to such scenarios on a flexible basis.

intrablack®

For the degradation of halogenated pollutants

intrablack® is the sustainable and exceptionally effective alternative to conventional iron – and this applies with equal regard to mobility during injection, sustainable reactivity and effectiveness as well as to CHC damage of every scope. Organic halogen pollutants such as PCE and TCE are effectively and permanently immobilised, being degraded into ethylene and ethane.

intragreen®

For the rapid, effective adsorption of pollutants

And on a sustainable basis: intragreen® can be precisely adapted to the different adsorption behaviour of the respective pollutants. For organic pollutants, intragreen® is used on the basis of highly efficient activated carbon.

For heavy metals and semi-metals such as zinc, nickel, lead or arsenic, we use colloidal organo-iron oxides which have a high specific surface area.

intrared®

For the highly effective precipitation of heavy metals

intrared® is a highly effective process for the precipitation of redox-sensitive heavy metals such as chromium, uranium or technetium. intrared® forms stable, redox-active precipitation zones in which the previously dissolved pollutants are deposited in the form of largely insoluble solids. In this way, the further displacement of the highly toxic pollutant in the effluent is prevented on a permanent basis. The deposit effect of the injections also prevents the rebound of the pollutant concentration.

intrawhite®

For the treatment of persistent pollutants

With intrawhite®, 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 (starting from 3-ring PAH), halogenated hydrocarbons such as dichloromethane and chlorobenzene, or MTBE.
