DEXSORB achieves its strong binding affinity from cyclodextrin inclusion complexes, that are optimally sized for the attraction and removal of micropollutants at the molecular level.
The highly porous nature of our DEXSORB adsorbents opens pathways for rapid access to the cyclodextrins, imparting rapid uptake kinetics for applications where short contact times and continuous water flow are required.
DEXSORB adsorbents contain cyclodextrin "cups" that are less than one nanometer in diameter, creating size-exclusion that resists fouling by larger inert molecules and naturally occuring organic particulates.
Effective at concentrations of one part per billion and less, DEXSORB adsorbents are uniquely efficient in the removal of micropollutants, requiring lower doses of material to achieve adsorption objectives.
DEXSORB adsorbents are easily regenerated using simple washing techniques allowing reuse for many cycles with unaffected performance.
DEXSORB is available in multiple particle sizes and can be optimized for maximum flow-through performance in any water treatment application.
Our DEXSORB adsorbents offer superior performance against micropollutants compared to activated carbon, a nonselective charcoal introduced over 100 years ago. From dosing requirements to adsorption rates to life cycle costs, DEXSORB is a 21st century technology that solves the pervasive problem of water contamination by harmful chemicals in dilute concentrations of one part per billion and less.
DEXSORB vs Activated Carbon
DEXSORB MP achieves full removal of micropollutants such as Bisphenol-A (BPA) in seconds as compared to minutes for activated carbon.

DEXSORB PFAS can reduce PFOA levels in groundwater to meet 2017 EPA and New Jersey limits.
DEXSORB significantly outperformed FS600 activated carbon in the removal of PFOA and PFOS in high concentration studies with a diluted AFFF solution.
