  • MFR - Modified Fenton`s Reagent for In-Situ Chemical Oxidation (ISCO)

    MFR - Modified Fenton`s Reagent for In-Situ Chemical Oxidation (ISCO)

    ISOTEC's modified Fenton's reagent (MFR) is based on the fundamental principles of Fenton's chemistry. H.J.H. Fenton first demonstrated the use of Fenton's chemistry in 1894 by oxidation of tartaric acid using a soluble iron catalyzed decomposition of dilute hydrogen peroxide under acidic conditions. ISOTEC's modified Fenton's reagent was developed with the fundamental goal of enhancing in-situ treatment of soil and groundwater contamination using...

  • Soil Mixing Expertise and Turn-key Environmental Remediation Services

    Soil Mixing Expertise and Turn-key Environmental Remediation Services

    ISOTEC provides soil mixing expertise and turn-key environmental remediation services to treat complex sites with high contaminant concentrations using oxidants (ISCO), reductants (ISCR) and metal stabilization reagents. When applied properly, soil mixing can effectively homogenize site soil and uniformly distribute reagents to targeted treatment zones, despite heterogeneous hydraulically conductive media. Additionally, there are no reagent...

  • In-situ Heavy Metals Treatment

    In-situ Heavy Metals Treatment

    ISOTEC offers in-situ heavy metals treatment via two technologies – calcium polysulfide (CaSx or CAPS) and ISOTEC Fe catalyst (AB24). Additional reagents utilized include FerroBlack®, sodium metabisulfite and sodium thiosulfate. In-situ chemical reduction treatment is a comparatively economical and rapid alternative to pump-and-treat. Furthermore, complex subsurface mixes of heavy metals and organic contaminants (e.g. VOCs, SVOCs) can be...

  • GTR - Gas Thermal Remediation

    GTR - Gas Thermal Remediation

    ISOTEC is now part of the GEO team implementing Gas Thermal Remediation (GTR) for In-Situ Thermal Desorption (ISTD), Ex-Situ Thermal Remediation, Thermal Conductive Heating (TCH), and Thermally-Enhanced Vapor Extraction (TEVES) projects in North America. GTR units heat by natural gas or propane allowing the greatest flexibility in thermal remediation while being reasonably priced compared with current thermal remediation alternatives. The systems...

  • Soil Treatment and Soil Stabilization/solidification

    Soil Treatment and Soil Stabilization/solidification

    ISOTEC provides in-situ soil stabilization (ISS) expertise and turn-key services that include certified laboratory treatability testing, and mixing systems that include innovative binder delivery and single or dual-axis soil mixing equipment to remediate manufactured gas plants (MGP), heavy metals and LNPL & DNAPL concentration contaminated sites. Dust control and odor control are maintained and fuel efficient equipment is utilized.

  • Environmental Remediation Services

    Environmental Remediation Services

    ISOTEC's environmental remediation services include in-situ injection of oxidants (ISCO), reductants (ISCR)and bio-enhancement reagents, in-situ and ex-situ mixing using oxidants, reductants and stabilization reagents, and thermal remediation of soils using natural gas or propane as a fuel source.

  • Activated Persulfate In-Situ Chemical Oxidation (ISCO)

    Activated Persulfate In-Situ Chemical Oxidation (ISCO)

    ISOTEC's persulfate technology uses sodium persulfate catalyzed by our patented modified Fenton's reagent, alkaline reagents (including sodium hydroxide and lime), hydrogen peroxide or our patented chelated iron complex to produce sulfate free radicals that attack contaminants. Persulfate when used as an in-situ chemical oxidation reagent is particularly effective at treating contaminants from aromatics like benzene, toluene, ethylbenzene, xylenes; and...

  • Permanganate In-Situ Chemical Oxidation (ISCO)

    Permanganate In-Situ Chemical Oxidation (ISCO)

    ISOTEC uses either potassium permanganate (KMnO4) or sodium permanganate (NaMnO4) for in-situ chemical oxidation (ISCO) treatment of chlorinated solvents. The reaction mechanism associated with both the permanganates is similar. Permanganate is particularly effective at treating aqueous concentrations of perchloroethene (PCE) and trichloroethene (TCE) in environmental remediation projects.

  • Ex-Situ Thermal Remediation

    Ex-Situ Thermal Remediation

    GTR-E is an evolution of the GTR line of technology specially designed for batch ex-situ thermal desorption of onsite excavated soils. The contaminated soils are excavated and placed in a pile. While building the pile, heater tubes are layered following a 'lasagna' process: a first series of heater tubes are placed atop a first layer of contaminated soil, and then covered by a new layer of contaminated soil, wherein the process is scaled as necessary for...

  • In-Situ Chemical reduction (ISCR)

    In-Situ Chemical reduction (ISCR)

    ISOTEC remediates sites contaminated by hexavalent chrome using reductive reagents that include chelated iron, calcium polysulfide (CAPS), calcium/sodium polysulfide and lactate. Environmental remediation services include laboratory treatability testing, mixing and injection services. Reagents can also be delivered using soil mixing techniques.
