Provectus Solid ISCR Amendments
… safer, modern, most effective, field proven
circa March, 2004 (San Diego, CA): during a discussion between scientists now at Provectus and Dr. Dick Brown (retired) regarding the emerging concept of injecting ZVI + fermentable carbon into an aquifer (see abstract AEHS, 2004), Dr. Brown coined the term “ISCR (the dark side of ISCO)” to describe the concept of creating conditions for in situ chemical reduction. Since this time, the ISCR acronym has been used more broadly than our original intent (see Brown et al 2009; see Dolfing et al 2007). And a variety of “ISCR-type” remedial amendments that combine myriad types of fermentable carbon + a range of reduced metals have entered the remedial marketplace.
Selecting an ISCR amendment in today’s marketplace can be confusing, but the choice can be greatly simplified. Provectus controls six USA patents (additional patents pending) covering our ISCR technologies and processes. And we uniquely provide Provect-IR® and Provect-IRM® antimethanogenic ISCR amendments to actively manage methanogenesis during the treatment process (see Mueller/Booth paper).
Proven effective, with numerous international case studies
Treats a wide range of contaminants
Multiple hydrophilic, nutrient rich organic carbon sources
Various particle size ZVI
Chemical oxygen scavenger
Made in the USA, Europe and Taiwan
Provect-ir® and Provect-irm® for Soils Conventional ISCR Amendment
Similarly, Provect-ir for Soils is a specially formulated amendment for surface applications via soil mixing and land-farming to treat nitrogenous energetics and organochlorine pesticides in soils (see here for technical paper, or see here for comparative study); Contact us for a competitive price quotation.
PROVECT-IR® Solid Antimethanogenic ISCR Amendment
PROVECT-IRM® Solid, Antimethanogenic Reagent for ISCR and Heavy Metal Stabilization
POTENTIAL ADVANTAGES OF USING PROVECT-IR®ANTIMETHANOGENIC ISCR TECHNOLOGY
- More Efficient: Hydrogen yield calculations have shown that by minimizing waste of hydrogen by controlling excessive methanogenesis one can elicit the same response by using ca. 30% less organic amendment. Since it takes less time and resource to inject less amendment this can significantly lower overall project cost.
