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 centers. 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,m 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.
• Sustains lifetimes of the in situ adsorption barrier in the range of decades at 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 boosted nutrients and microorganism. The nutrients serve as electron acceptors for the micro-organisms greatly enhancing the microbial degradation of the sorbed organic contaminants under both oxic or anoxic conditions to extend the intrasorp capture capacity.
