Colloid Environmental Technologies Company (CETCO)

- Organic Adsorption Media for Environmental Remediation Applications



The ORGANOCLAY product line is a range of proprietary adsorption media that is highly effective in removing oils, greases and other high molecular weight, low solubility organic compounds from aqueous streams. The ORGANOCLAY products are specialty sorbents, altered to an organophilic state making them attractive to organic molecules.

The CETCO ORGANOCLAY products can prevent organic contaminant transport into waterways when used in sediment remediation applications. Their adsorptive capacity reduces the required cap thickness compared to in-situ sand caps. The product’s adsorptive capability provides a sub-aqueous chemical isolation of contaminated sediment mitigating organic contaminant transport into the waterway. ORGANOCLAY products have a high capacity for low-soluble organic compounds such as NAPL, PAHs or PCBs allowing for extended cap design life and reduced overall costs.

CETCO ORGANOCLAY products can be used as flow-through media for treating groundwater and leachate. They can be used in fixed bed vessels, disposable cartridges or in-situ in permeable reactive barrier applications. ORGANOCLAY products can be used as a pre-treatment to GAC filtration to increase overall efficiency by preventing surface pores in the GAC from blinding caused by oils, greases and other less water soluble organics.
