ChromeSorb

ChromeSorb is a range of modified E-Clays specifically designed to chemically immobilise Chromium VI contamination. These products offer significant advantages over many existing technologies

ChromeSorb is a single stage process for the treatment of both chrome VI and chrome III, which can be ideally used / applied within our reactive permeable groundwater barriers, as well as for stabilisation applications.

The ChromeSorb E-Clay was developed to simultaneously chemically immobilise both the cationic (chromium III) and anionic (chromium VI) forms, both of which commonly occur at contaminated sites together.

Partially pillared modified clay showing inclusion of cationic (trivalent Cr & other metals) and anionic (hexavalent Cr) heavy metals

ChromeSorb can be applied as an additive in a stabilisation approach to control leachate and / or can be incorporated into a reactive groundwater barrier to treat contaminated groundwater. In both instances the treatment is a one step treatment operation.

Extensive testing and several remediation applications have demonstrated the efficacy of this process.
