Intrasorp®

Specialized Colloidal Activated Carbon

Intrasorp® AC is a suspension that contains specialized activated carbon colloids. Its was developed and patented at one of Europe's leading environmental research centres. With Intrasorp® AC, we can create in situ adsorption barriers in aquifers to quickly prevent the spreading of plumes or delimit the leaching of source zones with respect to a broad range of organic contaminants.

The Intrasorp® AC suspension shows a superior subsurface mobility during its injection, an irreversible deposition at the target zone with the use of our mobility agent and a pronounced adsorption capacity for organic contaminants like petroleum hydrocarbon chlorinated solvent, pesticides and explosive residual.

• Adsorption of BTEX, PAH, mineral oil hydrocarbons for long-term immobilization of contaminants in groundwater plumes or source zones.
• Effective adsorption of a wide variety of further organic contaminants.
• Can be Injected into the aquifers as colloidally stabilized suspension via direct push or via existing monitoring wells.
• Irreversible deposition after injection of the AC colloids at the aquifer matrix; no uncontrolled remobilization from the in-situ adsorption barrier, minimizing renegade carbon contaminating, immediate cutoff of contamination plumes.
• Extends the operational lifetime of the in situ adsorption barrier to decades with no additional energy cost.
• Proven in practice during multiple full-scale remediation applications at field-scale.
• Drinking-water quality - Made in Germany and scientifically validated.
• Can be enhanced through the addition of nutrients and microorganisms, wherein the nutrients act as electron acceptors, significantly enhancing microbial degradation of sorbed organic contaminants under both oxic and anoxic conditions and extending the intrasorp capture capacity.
