High Affinity. Our HCAP adsorbents gain their strong binding affinity from cyclodextrin inclusion complexes, which are optimally sized for the attraction and removal of micropollutants at the molecular level.
State-of-the-Art Technology. Unparalleled Performance.
Our High-Affinity Cyclodextrin Polymer (HACP) adsorbents represent a leap forward in the safe, rapid, and cost-effective removal of toxic micropollutants from water. The novelty of our technology is to organize naturally “sticky” cyclodextrins into highly adsorbent networks with porous, crosslinked pathways through which micropollutants are drawn in and trapped within cyclodextrins. The result is the world's first high-surface area, high-affinity cyclodextrin adsorbents.

Polymer Adsorbents
CycloPure CD-MP
CD-MP achieves full removal of micropollutants such as Bisphenol-A (BPA)  in seconds as compared to minutes for activated carbon.
CD-MP is more effective than Coconut Coir Activated Carbon (CCAC) in the removal of hundreds of common micropollutants.
β Cyclodextrin
CD-MP
Effective against hundreds of industrial compounds, pharmaceuticals, pesticides, and other organic micropollutants. CD-MP is available in a variety of powder and granular particle sizes to meet filtration and water flow requirements of virtually any water treatment application.
CD-PFAS
Fluorine selective HACP for the rapid removal of PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate). Available in multiple powder and granular particle sizes.

Superior removal compared to activated carbon demonstrated in simulated groundwater, AFFF solution, and actual groundwater collected from contamination sites.

Ten times the affinity to PFOA/PFAS compared to activated carbon allowing lower dosages to achieve non-detect or advisory level concentrations.
β Cyclodextrin
CycloPure CD-PFAS
CycloPure CD-PFAS can reduce PFOA levels in groundwater to meet 2016 EPA and New Jersey limits.
Cyclopure CD-PFAS is far more effective than FS600 activated carbon in the removal of PFOA, PFOS, and other per/poly fluoroalkyl compounds.
