As one of the global pioneers of environmental remediation, we are dedicated to offering gentle, rapid, and permanent remediation of contaminated soils and groundwater with the latest procedures.
Our method: particle-based in situ remediation. We inject customized suspensions of patented nano- and microparticles for groundwater remediation into contaminated aquifers. The particles react with the pollutants on site, deep within the ground, in order to degrade them.
We assess contaminated sites on a fine scale to determine the type and extent of damage. For the exploration, we use an integrated package of measuring processes to collect all the relevant groundwater data.
We integrate all the data and collate them in the form of a three-dimensional conceptual site model. In this way, we simulate the NMP application and its impact on a targeted and customised basis.
Through the exact coordination of the particle mix, injection medium and injection process, the particles are specifically introduced to the critical areas of the damage in order to provide an intensive treatment.
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® 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.
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® 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.
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.
